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.

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?
