Topband: Fwd: Wellbrook receive loop performance

[Gary and Kathleen Pearse]

> 
> I've had a Wellbrook 1530 loop up for a few years on a rotator at about 20' It excels on a small city lot in nulling local noise sources off its sides. Far better than the MFJ and ANC noise nuller boxes and sense antennas I have used on 80 and 160. Legal limit 75' away on 160 hasn't killed it yet. I do have the rotator control cable and coax common-mode suppressed with ferrite cores at both ends. I get no RF feed back in the shack via the device.

> If the desired signal and noise sources coincide (for example there's a powerline 60' away between me and EU), it still provides a better S/N than my Inv-L in that direction.
