Re: Help... down to the last two cables.



For what it's worth, I went for X rather than + because you can build remote
polarisation switchers between vert, horz, LHCP and RHCP with less coax
relays and less loss. There's a very good example of this in both the RSGB
Radio Communication Handbook 7th Edition and the RSGB VHF/UHF handbook.
