I have had such an antenna for almost 5 years. About 75 meters long and at a height varying between 5 and 10 meters. It is fixed in five positions, two on my house, and three in trees in my garden. Based on the www.cebik.com simulations, my expectation was also as a local antenna on 80 meters, but it has turned out different: Now I have had QSOs with 65 countries on 80 meters, most of them using QRP CW and with all continents including Australia (... 100 W CW, not QRP!). Probably I have been lucky with special propagation that has helped me, Pedersen rays or what have you. It could also be that I have a stream through my garden which makes the soil especially favorable or some other reason, but anyway I am very happy with the antenna. The concerns regarding mounting on the house, RFI and coupling etc are of course independent of this and will reduce performance. 73 Sverre LA3ZA http://www.qslnet.de/la3za/ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
