I really like the 2.4 Ghz band, as it's convenient for WiFi access, I guess I'm a heavy user of VHF bands, listening to radio shows, talking with ATC and traffic while flying, and of course watching TV at our cottage with an homemade Double-Bay Gray-Hoverman antenna, but I guess it's better suited for UHF, still has kick-ass gain on the VHF-HI band... I used to listen a lot to the MF band at night, since I was able to listen to shows from as far as New York or Chicago most nights, but now that I have an XM satellite radio, and of course the fact I use GPSes most of the day, both of which are on UHF, I guess we could say that UHF is really my favorite International Telecom Union radio-frequency band...
Oh but there is one band out there that I really,really despise: terahertz and the legions of doom, ahem I mean the TSA, using it to harass people whose only crime is to freely move around...
