re: 8GHz, there's plenty out there in the 7/8 GHz band for FDD... It used to be restricted to AM/FM/VHF and UHF TV broadcasters. Now it's not, in a big part of the US. See:
http://www.comsearch.com/newsletter/WirelessPulse.html Less availability of equipment than the regular 6 and 11 GHz bands, however. 7 through 9 GHz is also used for NATO (X-band) two way satellite stuff, the BUCs are very similar to large C-band BUCs for models in the 20W to 400W range. You thought your EIRP and path loss was high, try putting 400W Tx (consumes about 2400W electrical load) into a 37dB gain dish.
