Receiving loop aerial for 1.8 MHz - Bulding notes of a receiving loop antenna for 160 meters band

QM5 Yagi for 2 meters band - The QM5 antenna is a simple 5 elements Yagi with 1.88 m boom length for the lower 144 MHz SSB/MGM band, I used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 9.17 dBd; i.e. 11.3 dB forward gain over the isotropic radiator, while the F/R is about 11.5 dB. Elements

Cheap antenna to make from 160m - 6m  ^pop - The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD
