Topband: Low frequency RX antenna

[Tim Duffy]

Hello Ed

There is very little interaction between nearby loops. We are studying
interlaced loops that are 90 degrees to each other for four azimuth
coverage. I would keep the loops at least 25 feet away from other radiators.
Also be careful of RX overload from nearby TX.

Thanks Tim.  I assume you have three fixed loops. What, if any, interaction
is there between loops? That is, does the close proximity of one loop
affect the directivity of the other loop? Do you suggest a minimum distance
between loops or other  potentially resonant structures such as towers?
