Common Mode Chokes for RX Antennas

Challenged by the QRM picked up by my omni directional active RX vertical when trying to work TL8TT on Topband, I decided it was time for a directional RX antenna pointing south in addition to my N/W and N/E Pennants. I had a transformer and termination resistors collecting dust so I decided to throw out some wire to make a short BOG,

Topband Vertical 2013/2014 season

The top band vertical at SE0X was put in place just in time for CQWW CW. This year the antenna is a little stronger (and longer). The bottom section is now made of a 60 millimeter aluminium tube with 3 millimeter wall thickness and I added a more robust delrin isolator. The total heigh of the
