Second article on the rain gutter antenna.
Gutter loop antenna. Signal reports on 30 and 40 meters my primary bands have been consistently good. First you have to use a tuner.

I built variations of this antenna when i lived in several rental homes on hawaii island shortly after getting my novice class amateur radio license back in 1977. This hoa buster antenna defeats the rules imposed upon amateur ham radio operators by using existing metal gutters as an antenna and enables external tuners to achieve a near perfect match from 10 80 meters.

It is 80 feet long and off center fed as a windom with a single wire lead in to a tuner. Also less interference is created to neighbour s tv etc from cw than ssb. 1 top of mast mount 1 riser 1 eight foot jumper wire with clips 1 alpha match.
