TV antennas have compromises built in.. All of this it tied together and the efficiency is greatly compromised. Also, there is no elements cut for the 3-meter FM broadcast band. You must rely on the VHF-lo elements, which are designed for Mc. This has directional selectivity limitations: Because the wavelength of the signal is too small for the VHF-lo elements, the antenna’s front to back ratio it’s ability to select signals directly in front of it, but reject signals from behind is very poor to nonexistent. TV antennas tend to have many lobes, scattered around the azimuth plane, looking sort of like a starfish pattern, at Mc. The behavie psuedo omni-directionally at these frequencies. You’ll pick up lots of stations in a metro area or suburb, but you’ll also have a lot of non-local stations with co-channel interference from other non-local stations. For instance, you might be trying to receive a station in Patterson, NY, 23 miles away, but receive interference from a New London, CT station on the same frequency, 72 miles away off the back of the antenna beam.
Connecting an Antenna to Multiple TVs
If turning these items OFF is not practical, consider moving your radio away from as many of these noise-generating electronics as you can. Concrete, brick and steel are enemies of radio signal. Naturally, if you have a radio in the center of a building made from these materials, radio reception will suffer. In general, get your radio near a window. For best results, place your radio near a window facing this direction.
Using trees for antenna supports is a double edged sword. At their very best, trees are frustrating. On a calm day, with your antenna strung from the very top limbs of a couple of well placed, very tall trees, trees are wonderful.
It is the private noncommercial use of designated radio frequencies. Ham radio can be used for socializing, experimenting with wireless communication, emergency communication, and more. Ham radio is an incredibly diverse world. Her year-old son may also be a ham enthusiast. Ham radio operators communicate through many different means. While voice is obviously most common, they may also use Morse code, radio teletype, packet, PSK, and even pictures.
Ham Radio Benefits Why is ham radio exciting? Here are some of the top reasons cited by ham enthusiasts: It is a fascinating hobby if you are interested in radio and communication technology. You can communicate from literally anywhere in the world, even the peak of a mountain or the middle of a desert. Ham radio is incredibly useful during emergencies. Ham radio operators can coordinate rescue and supply missions when other communications fail.
You get to join a community of more than two million users around the globe. Licensing Requirements Licensing is a requirement for Ham radio, but the process has been streamlined over recent years.
FM antenna? Can I use TV’s?
Antennas Home-made antennas can greatly improve the performance of AM and FM radios, short-wave receivers, and scanners. If you are a talk-radio fan then experiment with the AM band antennas and you will be able to hear shows from all over the country with surprising clarity. Short-wave receivers are always coping with weak signals and they must have a good antenna to perform adequately.
Scanners can pick up local police and two-way radio with the little telescoping antenna provided but with good antennas a scanner becomes an amazing ear on the world nearby. No pre-amp, filter or other receiver refinement offers anywhere near the level of performance improvement t that a well-designed antenna offers. The results can be quite satisfying, leaving no doubt that the project was well worth the effort.
Anyone who wants a cheap and easy way to get HD programming from major and local networks should give an indoor TV antenna a try. TV antennas are perfect for people who are fed up with expensive cable TV subscriptions and get most of their viewing fix from online streaming services such as Netflix, Hulu, Amazon, and Sling TV.
Weather What type of feedline coax should I use for my antenna A common question that I receive is what type of coax cable should I use for my J-Pole antenna. This is a great question, as the coax you select can make a dramatic difference on the performance and range of your antenna system. There is a wide variety and choices of coaxial cable available and each type serves a different purpose. All coaxial feedline cables will exhibit signal loss.
The amount of loss is dependent on three factors, the construction of the cable, the frequency of the signal, and the feedline length. Balancing these variables is crucial in getting a solid signal out of your antenna system. It is reasonably affordable and easy to work with. If your cable run is going to be longer than feet, or you are installing a UHF antenna for 70cm amateur radio, public safety, or GMRS; then I would recommend a low loss cable like LMR , Belden , or similar shielded low loss cables.
These cables have a heavier center conductor and an additional layer of shielding to better carry high frequencies with minimal loss. What about RG or RG-6 cables?

Introduction The purpose of this section is to provide the information necessary to make rational decisions on products, with the goal being to connect to the Internet from your RV. The idea is to make sure that all of your local devices – computers, tablets, wireless printers, TV, DVR, etc. In a home environment meaning a “fixed” environment only one method is typically used to connect to the Internet – often that is DSL or Cable.
I am going to mount it on the is a magnetic base.I would like to know the best route for the cable and how to install it on this radio unit will be located just below the am/fm radio.
Not open for further replies. If you’re in need of a great, directional FM indoor antenna and don’t want to bother doing the “right” thing that is Many Walmart’s have them and also many BestBuys. This makes it easy to “try” one to see if it works well in your environment. Why I bought one: I had one of these hooked as an over-the-air antenna to my TV set while I was in Chicago on assignment last year. Just as an experiment: I was sure that most of it’s directionality the more directional an antenna is, the more “signal reception” abilities it has was optimized for the TV UHF band and that directionality on VHF especially at frequencies as low as the FM band would have been mediocre at best.
I hooked it to the FM tuner with about 25 feet of RG-6 coax so I could move it around my listening room. I was shocked to hear that stations were flooding in from as far away as Grand Rapids miles , Kalamazoo 75 miles , Chicago 95 miles , and Fort Wayne 85 miles. Turning the antenna around to different positions would null out a station from one direction and bring in another station from a different direction on the same frequency.
How to Connect a Stereo System
Dipoles work OK when the signal is adequate, but when multipath is stronger than the direct signal AND the tuner has inadequate alternate channel selectivity, it’s time to forget about clear reception and that’s what I have here- as I wrote, I’m very close to an antenna farm and that’s not good for someone who likes to listen to a college station that’s weaker than all of the others.
Here’s a photo of the kind I’m referring to. It’s possible that some are two wires, but many aren’t and I have seen several that had been cut.
Connecting Your Receiver to the Antenna Joseph J. Carr fancy way of saying a single wire downlead. The ground terminal is also seen in Fig. 4. “A2” terminal is strapped to the “G” terminal with a short piece of hook-up wire (some receivers use a small metal link that must be removed before a balanced antenna is used).
Share27 Shares I was at the playground watching my kid play on the ground when I struck up my favourite conversation with my friend Nadine. We chatted about cutting cable television. The conversation may have gone something like this: That math totally works. I use an HDTV antenna to watch cable channels for free. I get two channels. I either love you or not.
Both DIY TV antennas worked perfectly well, as long as Carl held it while I leaned out the window with a raised hand and a bent knee that either resembled a sad pink flamingo or a poor interpretation of that 80s Bangles hit, Walk like an Egyptian. Both attempts made the option of just paying for cable television look a lot less ridiculous.

This is how my antenna replacement worked for me and my SR5 4 cyl 4×4, your truck may vary! If in doubt, head to the dealer and ask for your specific diagram! As I couldn’t find any good pictures before I attempted this myself, I thought I would type them up to assist anyone else out there. What follows is how to replace your Antenna the part in your fender with a OEM replacement.
Here is what you will need:
The stock antenna, while functional in most situations, can struggle with weak radio signals. Using an amplified antenna can improve reception in these situations. You can use any FM antenna, as long as it uses a 75 ohm, F-type connector.
Counterpoises Technically a true “longwire” needs to be at least one wavelength long, but Hams commonly call any end-fed wire a longwire or random wire antenna. Long wire or random wire antennas are very simple antennas. They can come close to half wave antennas in efficiency, although efficiency decreases as they are made very long or installed closer to earth. Like every antenna that exists, random or long wires have advantages and disadvantages.
Advantages no heavy expensive coaxial feed line hanging from the span single wire “feeder” and “ground lead” radiate very simple to install and construct can be a problem for lightning excellent stealth antennas single wire feed line can be burn or shock hazard inexpensive require a tuner or matching system Because the radiating area is often brought into or near the operating position, longwires often create RF interference to consumer goods or RF in the operating room.
The easy installation part comes from generally needing only two supports, and not having a heavy feed line hanging from mid-span like a dipole. The long expensive feed cable normally associated with a doublet or dipole is not needed, the antenna wire itself serving as a “feed line”. The antenna itself works just as well as any other wire of similar height and length.
Any or all problems are in the counterpoise and feed system. The difficult problems associated with random wire or longwire antennas are caused by ground currents and radiation from the single wire feeder. End-fed antennas, or antennas with the single wire feeder brought into the shack, come with a little misconception. One commonly repeated myth or “theory” is that half-wave antennas, being resonant, do not require a counterpoise , or that some magical length of antenna will prevent RF in the shack.
The Best Indoor HDTV Antenna
Long wire or random length antennas, built the way most people do it, are very poor antennas. Here are a few reasons why. Most people just connect a long piece of wire to a tuner and that’s it. That is half an antenna, the other half is your house wiring. This picks up lots of noise and is very inefficient at radiating. What radiation that is done goes directly into TV cables, computer cables, power wiring, etc.
String up an antenna wire outside and bring the end inside. You can either place it near the radio, attach it to the radio antenna, or wrap a loop of it around the radio and ground the end.
Untitled Document Tips for improving tuner signal reception: Radio signal quality can be influenced by several factors when operating a tuner inside of a building. If you are having trouble receiving FM radio transmissions, you can try some of the following steps: Ensure that the FM antenna is connected. It is a length of grey wire with a plug on one end.
Stretch the antenna out to its full length.
While this is tolerable in some situations, if the place that you’re not getting good reception is in your home or office, then that becomes a problem that you really need to fix, otherwise you risk missing important calls, dropping a call during a critical conversation or not having reception during an emergency. In this guide, we’re going to discuss what causes a weak cell phone signal, poor reception, and dropped calls.
Then we discuss what a cell phone antenna booster is and how one can be used to amplify your cell phone signal, improve reception, and eliminate dropped calls.
Most of the better FM radios and home stereos have some provision for an external antenna hook-up, and/or a built-in antenna rod or wire. The rod or wire may not be the prettiest thing, but, moving them around and/or stretching them out to their fullest often gives significant reception improvement.
The RF amplifiers use a combination of tuned grid input and tuned plate output using a three-section ganged tuning capacitor. The antenna switch allows the user to select which receiver will be connected to the antenna – either the AR or an emergency receiver. The audio output can drive the panel mounted loud speaker or headsets either simultaneously or, using the Loudspeaker switch, the panel speaker can be turned off.
The receiver requires a separate power source of which many types were available. These functioned on ships that provided vdc or vdc power. If vac was to be used then the RM Rectifier power supply was used. The AR requires 6. Top of the chassis showing the antenna connections far left front of chassis and the power input connections far right back of chassis. The tuning condenser is under the central cover.

One of the ohm teminals may also be marked 75 ohm, with a line or some sort of marking “linking” it to the ground terminal. The ordinary cheap “T” FM antenna would connect to the 2 terminals marked ohm. Your speaker wire might make do til you can scrounge or buy a “T” antenna. Just take a 6 foot length or so and separate one end of it so the two ends are ” apart when spread out to the shape of a “T”. Separate the opposite end a few inches, strip the ends and attach to the ohm terminals.
If you need to hook up a wire antenna to a FM Loop and repeat YouTube videos, repeat any part or the whole YouTube video, play YouTube videos continuously with VideoInfinite Your videos will automatically start looping from beginning to end, and you can arrange the loop time via slider below the video.
I have tried all kinds of wires, antennas, even trying to use the garage itself as the antenna with no avail. I have heard before that most home style radios don’t have enough “antenna power” to run real long wires to roof antennas and whatnot. I get a few stations but the one I really want doesn’t come in at all. I could not agree more. I got tired of the two local corn dog stations playing either gangster rap or Barry Manilow type diarrhea all day long and went the internet radio route as well.
I had a cheap computer out in the shop anyway with a wi-fi internet connection so that was an easy choice. You may still have to run a cable if the wi-fi won’t penetrate, but you will end up with a virtually unlimited number of stations in any genre you can think of. Thousands of stations and crystal clear reception, what’s not to like? So tell me, is this basically “streaming” audio from a website? Willy So tell me, is this basically “streaming” audio from a website?
You can search for a particular radio station that has streaming internet audio, as most do, or you can access internet radio portals. Do a Google for internet radio stations and you will be inundated by the number of options, same goes for the number on the portals. Have a look, this is only a very small sample:
