Hi folks
The Waller Flag is a high performance antenna, however the station should be well grounded. Using toroid chokes it is possible to know down common mode noise. N8PR is working hard to clean all the unwanted noise on his station here in Fort Lauderdale. Pete station is very close to 50KW BC AM station. Lots of choke still need to be installed, however the initial results are very interesting. Pete has a magnet loop and on the video I uploaded to YouTube shows some competition between WF vertical and horizontal. One of the last layer of noise removed was common mode noise coming from the rotor cable. Pete demonstrate on the video how the impact of a choke on the rotor cable. If you have other strong noises you won't see the same result because first you need to remove the top layer of common mode noise. I hope you guys enjoy Pete's video. https://www.youtube.com/watch?v=-4os4qcaT08 Regards JC N4IS See you guys at Dayton. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
