...I took the SDS100 in the field today and the results were slightly better in some areas, and not in others. I am at a loss as to why they bothered to include the air band at all. I parked directly across from Teterboro airport in NJ, the nation's busiest private commuter airport and could barely read comms between the tower and aircraft. They were hidden behind a mountain of white noise and hiss...
What antennas did you use besides the REMTronix in "the field"? Was that the REM-810S or REM820S? Or did you not bother buying them (the SDS100 versions) since Amazon doesn't carry them and you couldn't easily return them? Did you use a BNC adapter for the antenna tuned for 700-900MHz?
Did you bother with the stock rubber?
You mention UHF...like the whole 300 MHz - 3 GHz range? Or the aircraft band that spans VHF and UHF?
Where you outside of a vehicle by Teterboro?
I've had to turn off Close Call (eventually removed air) with the stock rubber because the aircraft hits were annoying as hell for me.
The smaller battery was warmer to the touch but the larger battery was barely noticeable for me.
