    Homemade TV antenna

    OK let me make it simple. The length of an antenna is determined by the frequency of the signal you want to transmit or receive. The frequencies closes to those that the antenna is tuned to will come in strongest and those farther away from the frequency of the antenna will be weaker. By changing the lengths of the elements of the antenna, you change the frequency it receives. If you change it enough it will no longer receive in the television band.While there is a lot of leeway in the materials, the diameter of the antenna must remain about 26 inches.

    No television is in a different frequency range. Ask your dad to explain it.

    the center conductor of the so239 is soldered to the antenna wire going up. The outer connector of the so239 is where the ground/reflector wire and just passes through a hole to the inside of the mast and hangs down the inside of the mast.http://www.k4icy.com/dipole_connector_so239.jpg

    It just hangs there

    By how big, you could mean the length of the antenna or the height above the ground. The diameter of the antenna is fixed. By changing the lingth of the antenna. you will change the frequency. The more you change the diameter the more the signal will be degraded.As for height above the ground, The higher the antenna. the better it will work However there are restrictions on height in some areas. If you live close to the flight path of an airport, call the airport and tell them where you live and they can advise you on height restrictions. You can also call your city and see if there are any other height restrictions for your area. If you belong to a homeowners association, check with them. Some do not permit antennas or towers. At some point you will be required to have a light on top t...see more »By how big, you could mean the length of the antenna or the height above the ground. The diameter of the antenna is fixed.

At some point you will be required to have a light on top to warn aircraft of it's presence. Pretty much everywhere, you are restricted to 500 feet so it does not interfere with aircraft as they stay above 500 feet except for landing or take off..In most areas you have to have room if it falls, it will stay on your property. In other words, if you have a 200 foot tower it must be at least 200 feet from your property line. A 1 acre piece of property is approximately 200 feet by 200 feet, so you would be limited to 100 feet if it is in the center of the property.
