7/8 has smaller channels though, right?

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.

And all that on the same antenna. Those horns are good from about 3.2GHz up to something like 13GHz IIRC. Amazing stuff for the late 50s / early 60s. Terry has a bunch of that 4GHz rigid rectangular waveguide laying around. No idea why he doesn't scrap it since it's all useless. He just doesn't like letting go of some things.
