Best results are on the main Tx aerial into my R5000 but, failing a suitable giant relay, I have to use experimental systems instead. Thanks to GW0NOS in particular I am able to compare results. The latest aerial is a long ferrite rod with high-gain amplifier, end on loss is about 10dB. Due soon is a vertical strip in a tube, I understand height must be the main factor with these. Hugh, M0DSZ
