On 80m here in vk we have 3.500 to 3.7 es 3779 to 3.8 dx window. yes it is a jump cw to ssb " but' i switch in a extra matching network at the phasing box, this is not perfect as the phasing line r to short. but a much better method than to try to match at the rig end..i use triangle phase array.. 3 by 1/4 verticals wid 120 radial per vertical..
