I've had a Wellbrooke loop for a few years at 20' on a TV rotator. It nulls a single nearby QRN source NW at 300 deg true. EU is about 15-30 deg from here. When 160 or 80 are open over the N Pole, it often helps me hear the weak.
It's less effective on multi-source QRN, but still helps at times if I rotate the loop to null the loudest noise and max the received signals. No room for other receiving antennas, and the loop ignores legal limit transmissions on a 120'x120' lot. What more can I ask? 73, Gary NL7Y > I originated some discussion recently on this list and the guys that had > tried this type of antenna all said that they would not buy one of them > again. > You can search the archives for the comments. > > Dave Harmon > K6XYZ[at]sbcglobal[dot]net > Sperry, Ok. > All good topband ops know how to put up a beverage at night. _________________ Topband Reflector
