Amateur Radio Antenna

imsety An amateur antenna must be no higher that 200 feet. This is measured from the ground level at the base of the tower up to the top of the antenna structure.

In this series we#39;ll cover consumer and amateur radio, antenna setup and design. This is just a fun intro into the world of short wave and HAM ...

I am looking into building an antenna that was featured in the December 2008issue of CQ. It calls for 10 or 12 gauge solid copper wire. I did a search through Radio Shack and I am coming up with several types of wire.
What type of wire should I be using for this antenna?
Thanks.

Anybody have any good plans for a all band end fed wire antenna ? limited space and i dont want to upset the niegbours so low visibility would be good.

There is a difference between a long wire antenna and a long piece of wire used as an antenna.

The former is the correct name for an antenna which is several wavelengths long at the frequency of operation.

The latter is simply a piece of wire which you think, subjectively, to be long.

For low visibility, use very thin wire. Enamelled copper (I think it's generally called magnet wire in the 'States) of something like 32 s.w.g. (sorry, don't have tables at hand to give the U.S. equivalent) will be invisible to your neighbours - and to you, so be careful.

Suspend as long a length as you can manage. Erecting it in a zig-zag across you land or yard will allow you to get more length.

I expect that you know you will need an antenna tuner and a good earth connection from the transmitter and receiver for best antenna efficiency.

Best of luck.

Yes, you can lose 75-90% of your radio reception by using sprayed radiant barrier. Even worse, sprayed on radiant barrier doesn't even work well. The aluminum must not be physically touching anything else to reflect heat properly, so only radiant foil stapled to the rafters is effective.
