I've programmed my TD-H3 radio to listen in on the nearby airport. Can be interesting at times. Currently at my house, behind the small hill it's just static. If I put it on my base antenna it's perfect. I can hear the tower and all the airplanes responding.
My shop is 1/2 mile from the airport and I'm in a metal building. I keep the radio in the window using a Nagoya 771G antenna and I can hear the tower and some of the planes. Mostly the planes are just hash and not understandable.
Is getting an antenna tuned to 120MHz really going to do anything for my reception? It would be in the same place, in the window. I keep it there and I can hear the 3 repeaters I use (7, 17, 21 miles away). I find it very interesting being 1/2 mile away from the airport and not able to hear the airplanes where I can hear them at my house which is another 2 miles away.
