What do you need to know about over the air antennas?
All About Over-The-Air Antennas (OTA) An off-air antenna is a product people use to receive over-the-air signals from broadcast TV stations. In order to use an antenna, your television must have a built-in TV tuner or you must have an external tuner connected to the antenna and television.
Can a large roll of wire be used to build a radio antenna?
If you plan on building several antennas, you should have no problem with this large roll of wire. What Works with What Current. Regular DC or AC current and voltages travel through the center of the wire, whereas RF runs on the outer portions of the wire. Picture if you will, a wire with the cut portion of the wire pointing at you.
What’s the best way to make an FM antenna?
Cut off one end of the coaxial cable. While you’ll want to leave one end of the coaxial cable intact in order for it to serve as the connector, the other end will need to be removed. You can use your wire cutters or a hacksaw to do this. Strip half of the antenna’s overall length from the end of the coaxial cable.
How big of an antenna do you need for a cell phone?
Cellphones use radio waves too, also traveling at the speed of light, and with a typical frequency of 800 MHz (roughly ten times greater than FM radio). That means their wavelength is about 10 times shorter than FM radio, so they need an antenna roughly one tenth the size.
Where to place a CB radio antenna on a car?
Ideally, keep 2/3 of the antenna above the roof height. Try to keep at least 2/3 of the antenna above the roof of the vehicle for best performance. Mounting a flexible antenna too close to the body can cause it to make contact with the body and can cause SWR and/or performance problems. For single antenna installations, use 50 ohm (RG-58A/U) coax.

Where is the best place to set up a radio antenna?
Look for low hanging power lines, and stay away from them at least by one and a half lengths of the height of your longest pole closest to the power wires. The closer you are to your radio room, the better off you will be. Back yard antennas, right close to your radio room, or radio shack, make it easy to set up and operate.
Is there a problem with the afterrmarket radio harness?
First, if your car is a 1996 or earlier model, don’t bother — the K-Line doesn’t go to the radio harness and there is no possibility that that the car has this problem. If you have a Vag-Saver : Simply turn the ignition ON and plug in the Vag-Saver. Look at the LED. Green is OK, Red is not OK.
