Bob you and DB, are  going to really get down on me hard for recounting the following experience I once had with just such a choke as David describes.


The story goes back to when Bob got his original AstroPlane, and I was telling him I had my New Top One up and it was acting bad with RFI here, and I still have it up and working.


At the time I had my feed line outside and flat on the ground, and in the past I swore that doing this before seemed to help mitigate my TVI problems. Well in this case I reported to Bob terrible TVI, and asked him to test for the TVI when he installed his NO A/P. That was in the fall and he said he had to wait until spring before he could get around to doing such testing with the A/P.


Well one day a while back my daughter was going to cut my back yard, so I picked up my feed line and wrapped the excess into a random loop, put a rope around it, and tied it to my antenna P/U pole as shown in the image below.


Later I discovered my TVI was gone and the coax coil in the image below looks very similar to what David shows on your link. Before I did the choke I could not key up but 25 watts now I can do 100 watts with no effects in the station.
