Can I use speaker wire for an AM antenna?
Can I use speaker wire for an AM antenna?
Definately yes. In theory, every metal can be used as antenna with varying results. In order to achieve maximum signal strenght in FM band, opt for a lenght of 28 inches ~(72 cm) of speaker cable (both strings), split it to create a dipole antenna and connect the wires to the “balanced” input of the tuner.
How can I make my AM antenna stronger?
You can get better AM reception by using an external antenna such as a loop antenna, placing your radio near the window with its rear facing outside, or switching off/moving away any electrical appliances that have been proven to interfere with your radio’s reception.
Does a long wire antenna need a counterpoise?
On higher floors you’ll need a counterpoise. A counterpoise is simply a long, insulated wire that attaches to the ground connection on your antenna tuner. That’s a lot of wire at, say, 3.5 MHz, but you can loop the wire around the room and hide it from view.
How long should a long wire antenna be?
It is important to use a counterpoise. A standard recommendation (see QST, March 1936, p. 32, “An Unorthodox Antenna”) is an 84′ long end fed and a 17′ long counterpoise (6.5′ for 20m)….Wire Lengths for Various Band Combinations.

Can a TV antenna be used for AM radio?
The antenna (or lack thereof) will also greatly affect the signal strength. Most radios are designed for FM reception. Unless it’s a high quality radio designed for AM, any external antenna (such as a telescoping antenna) is probably for the FM. Again, there is a lot that can interfere with the signal.
Can insulated wire be used for antenna?
The short answer to the question as to whether or not you can use insulated wire for an antenna is “Yes you can”. Insulated wire will make your antenna appear physically shorter at the resonant point, but the difference is slight (estimated to be about 2%).
How long should an AM antenna be?
if you read the instructions that come with modern radios, like sony and such, they recomend an external antenna of no longer than 30 feet to prevent front end overload.
How can someone make a homemade AM radio antenna?
Have all of the things you need for making a homemade AM radio antenna set up. Have sufficient lengths of insulated wire with a gauge of 22.
How do you make a homemade antenna?
Attach the balun to the frame of the antenna. Connect the coaxial cable to the balun Attach the other PVC pipe to this frame using the PVC angle. Set up the antenna indoors or outdoors as per your requirement. Connect the antenna to the TV using the coaxial cable and tune your settings.
How do you make an AM radio antenna?
Quick Answer. Radio users can make their own homemade AM radio antennae by winding a coil out of single-strand wire, grounding the wire and putting a portable radio near the coil. Important supplies include single-strand wire, cardboard, tape and a wire stripper.
How to make an AM radio antenna?
Nail the two slats of wood together so that they form a cross. Two small nails should be enough to hold them.
