Topband: Mixed RF grounds

[Chortek, Robert L.]

I looked into this some years back and was advised NOT to mix ground and elevated radials.  Can’t recall why.

My elevated radials are bent in every possible direction, and cover only about 120 degrees of the compass. Still,  I’ve managed to work 147 countries on 160 and over 200 on 80 from a 11,200 square foot lot in San Jose, CA.  The point being, you can do reasonably well with a compromise set up.  Just do the best you can with what you have to work with and maximize your receive capability.

Good Luck and 73,
