Topband: K9AY minimum spacing from TX

Ash,

The answer is "as far as necessary"! There seems to be a lot of variation in the degree of interaction with towers and other antennas. Every QTH is different. 

I suppose 100 feet is a good starting distance. The minimum I've installed the loops at my own QTH is 75 ft from an Inv-L. Had no problem, but I think the Inv-L was at least partly detuned during receive by the T/R switch open circuit and length of coax.

Just try it, then be prepared to do some investigation if it doesn't work out. 

And yes, trees are not a problem.

Hi All,

How far should a K9AY be spaced from resonant antenna? I presume there is
no impact from nearby trees.

Please advise.
