Hey guys, so I hooked up a new folded dipole antenna on my roof to replace a home-made pvc all band antenna that worked fine but the range wasn’t great. The range on the folded dipole is better.
I’ve noticed something strange now though. On frequencies that are coming from further away and are a bit scratchy, there is a strange interference that I never had before. It sounds like a two-tone beep, high then low, about a second long, always accompanied by something that sounds like helicopter rotors spinning in the background. If the transmission is long enough, this cycle repeats itself. I can always hear the voices over these sounds. This only happens on analog VHF freq’s, not digital.
Here is the set up: Whistler TRX-1, 50’ RG6 to Centerfire folded dipole with 300 to 75 Ohm transformer. The antenna is mounted on the same pole on the roof as a wireless weather station.
Maybe the weather station is the culprit? But it never happened with the old antenna, and now it only happens on frequencies that seem far away, and only analog.
Any thoughts? Not a big deal, but the interference is strange, and I’d like to track it down if possible. Thanks!
