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.

Visually survey your property and find out exactly where your right to put up antennas and your neighbor’s right to tear them down ends. This sets your limits. If there is an XYL involved, the available space may be artificially restricted even further. If you are fortunate, you may have a neighbor who will permit you to use one of his trees to support an end of your antenna. Unfortunately, most neighborhoods seem to want an unobstructed view of utility poles, power lines and other people’s houses, so they cut down most of the trees.
Using trees for antenna supports is a double edged sword.
Jul 19, · The desire was to hook up an in-attic antenna for FM reception. I was gifted a fairly large HDTV antenna a few years ago and had not put it to any use so I figured I would hook that up as it had to be better than any set of rabbit ears I could pick up.
Rating This little bugger far exceeded my expectations! I was amazed at the number of stations available and the quality of the reception. Directions were easy to follow and set up was a breeze. I highly recommend it. We live twenty-five miles from the tv stations in a rural setting. I got the basic leaf and it works great. I got a second because the first did so well.
Now I have almost a couple hundred dollars worth of antennas that might as well be recycled compared to the Leaf. This was by far the best of the group – all the rest were returned. I am in los angeles and was using radio shack rabbit ears one but that antenna needs to be in higher position and you can’t fix that one on the wall. While this one just like a paper one and stick to the wall and looks nice. Got all the channels in once without adjusting antenna.
I am using regular this one without amplifier one and getting all the channels.
Build a DIY Recycled Antenna (To Get Free T.V!)
How to combine antennas that point in the same direction As described on the previous page, when a 2-way splitter is used as a combiner, 1. But something different happens when both antennas point at the same station Superposition Superposition is the technique for analyzing circuits that have multiple sources:
However, the antenna tuner, if it is installed at the output of the transceiver, will only keep the transceiver happy, but it will do nothing for the coaxial cable going to the antenna. The best place for a tuner is at the antenna feed point.
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.
FM antenna? Can I use TV’s?
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:
Connect #8 gauge wire to a copper clad ground rod driving it at least 4 feet into the ground. We would also recommend checking your local electrical codes to make sure you are in compliance or even look into having a professional electrician advise and/or install for you.
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. There are lots of good vintage FM tuners on eBay. However I do note your Public radio service is very limited compared to what we enjoy. That pretty much has you covered.
What cable/connectors to use between my radio and antenna?
Approximately how many feet above ground level will the antenna be installed?: Will the antenna be installed outside above the roof line or in the attic, other: Outside below the roof line 5. If the antenna will be installed in the attic what kind of building materials will the TV signal have to penetrate to reach the antenna in the attic?: How many TV locations within your home will the antenna supply? In other words, will a signal splitter be in use and if so how many times will the splitter divide the TV signal?:
The FM radio band falls between channels 6 and 7 on the VHF band, so a VHF antenna will usually work for FM as well. There are also channel cut antennas. These are antennas specifically designed to .
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. Then, work on the antenna…. Antennas matter, but almost nobody pays attention to them.
FM radio signals travel in a wave about 6 feet wide. Extending the antenna rod or wire out fully will give better results. If that rod or wire is at least 3 feet long, all the better! FM signals mostly travel horizontally, so, positioning the antenna rod or wire horizontally or diagonally will usually give better results than vertically. Here are some economical FM antennas available at your neighborhood Radio Shack stores that are worth trying out:
FM Tuner signal reception tips
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.
While you can watch local TV online, the best way is with an OTA antenna. Connecting one antenna to multiple TVs can sometimes be an ordeal depending on the signal strength in your area. Connecting one antenna to multiple TVs can sometimes be an ordeal depending on the signal strength in your area.
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. Do not coil the antenna. Separate the antenna from the other cables behind the receiver, especially power cables. If possible, try positioning the receiver near a window to reduce interference from building materials If the preceding steps do not sufficiently improve your signal reception, your next option is to use a 3rd party antenna. 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. We have included some pictures of this connection type below: You will find there are many varieties of FM antenna, ranging from indoor antennas, to roof-mounted; some are powered and others are not.
