I'm looking for a high gain VHF/UHF outdoor base station antenna so I can hear loud and clear both sided conversations of as many air traffic control (Tower, TRACON, and ARTCC RCAG) communications as possible with very little or no static. I'm mostly interested in the civilian band, but military would be good too. I'm even looking at 2m/70 cm ham radio antennas and can't figure out which one to buy since they have a lot of mixed reviews.
I've given up on Radio Shack base station antennas after several negative experiences, and recently put up a Diamond D-130J, and my airband RX is better but still very weak and mostly static. I have a 30' AGL outdoor chimney mount (2 story flat roof plus 10 foot fence pole) with commercial grade RG-11. My airband capable scanners are a Pro 106, Pro 96 and Maycom AR-108. Also I'm well aware that "higher is better" (I've been listening to scanners for 13 years), but my chimney is over 100 years old and the guy who sold me the mount said with brick chimneys that old, anything over 10 feet will make them topple, so more height is NOT an option unless I were to install a new freestanding tower. (I also have 2 TV antennas on the same mount btw). Also I'm well aware of the "line of site" rule.
Per Google Maps, I'm about 15 miles from KFNT, about 45 miles from KMBS, about 65 miles from KLAN, about 75 miles from KMTC, and about 85 miles from KDTW. I'd like to be able to receive strong both sided communications from all of them and possibly more.
So which antenna should I get? Would a high gain base station antenna alone even fulfill my wishes or would I also need an airband preamp?
I'd appreciate any recommendations and tips.
