In my restricted area yard about 15 mtrs across by 12 mtrs set up a horizontal loop for 40 metres. The loop consists of 41.84 mtrs of wire suspended from poles at each corner of the yard.
The poles raise the loop about 7 metres high. The loop is fed by 450 ohm ladder line with a 1:1 balun.
A short length of RG213 about 500mm comes in through an opening from the balun to an aerial tuner. Its important to keep this length of coax as short as possible.
The loop will tune 80M, 40M, 30M and 20M, have not really tried any higher bands as have a hex beam for those.
Get very good performance for local VK and plenty of dx on 30M and 40M, not really tried the loop on 20 or 80M for dx as yet.
One great attribute of the loop in a suburban location is it is very quiet as compared to a dipole or a vertical.
