A friend is contemplating antenna replacement before this winter, and is considering a HyGain TH11. Does anyone have any data comparing the forward gain and F/B of the TH11 to the TH7 on 20, 15, and 10 meters? We're wondering how much performance was sacrificed to add the WARC bands. Replies here or direct. Thanks Jim AA2JN jrb@rfc.comm.harris.com
