I too replaced a BN86 on my 204BA twice and that was before the move to Mississippi. However not all American product is built to low standards. The Hy-Gain Antennas were good for their time and held

The confession of a ham with no ground wire in his shack other than the AC mains follows. The shack is on the second floor and any ground line would be eighteen feet in length minimum. This house is

I use an Isopole on 2 meters and indeed there is a dead short. You can still get the instructions for the Isopole on line from AEA if you Google for them. It is a good antenna for its size and has a

The trouble with LP antennas and some multiband Yagis is that they have a very high wind load. The SteppIR avoids this with fewer elements. SteppIR, maintenance has been a problem for some and not fo
