[Antennas] antenna tower separation

Sat Dec 26 17:19:27 EST 2015

I recently bought a 5 acre parcel out in the high desert. The house is 
just about in the middle with a barn towards the back of the property. 
The power line runs down the west side of the place. Nothing else really 
close enough to bother anything i wouldn't think.
Question is, i want to put up at least 2 towers. One for a 20M beam @ 
50 ft as well as holding up a 40M dipole and a 6 mtr beam on top of the 
mast. On the 2nd tower i will have a 5 el yagi @ 25 ft for 15M and 
probably a 4 el 10 mtr beam above that.
I had the same arrangement when ni lived in town with the towers about 
30 or so feet apart and i could tell when one antenna was facing into 
the other. My question is, how far apart would be the minimum distance 
so that the antennas would not be so obvious to each other. I can 
separate them by 100 + feet but the cost of feedlines starts to add up. 
I'd think a minimum of half inch hardline would be used. I don't run 
more than 100W. I just would like to have the towers separated enough 
so that they don't "see" each other, if that's possible.
