It's 6.875 - 7.125 and max bandwidth is 25 MHz. Unfortunately, most congested areas are unavailable. ________________________________________ From: Af [[email protected]] on behalf of Mike Hammett [[email protected]] Sent: Wednesday, September 23, 2015 7:41 AM To: [email protected] Subject: Re: [AFMUG] 4700 MHz band and FAA
7/8 has smaller channels though, right? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ________________________________ From: "Eric Kuhnke" <[email protected]> To: [email protected] Sent: Wednesday, September 23, 2015 1:41:38 AM Subject: Re: [AFMUG] 4700 MHz band and FAA 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.

I've also heard that 8GHz was in use in some places. 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. On 9/22/2015 8:55 PM, Mike Hammett wrote: Didn't Long Lines operate there too? I think there's a commercial licensed band around there too, but no licenses issued in forever. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ________________________________ From: "George Skorup" <[email protected]><mailto:[email protected]> To: [email protected]<mailto:[email protected]> Sent: Tuesday, September 22, 2015 8:16:23 PM Subject: Re: [AFMUG] 4700 MHz band and FAA IIRC, 4.2-4.9GHz is all DoD.
