[OKDXA] Mini Tribanders at low heights

Yes, John. Every time I operate without a directional antenna for a 
while, I am always amazed at how much difference it makes, even if you 
have really good dipoles, loops, or verticals. The last time I learned 
that lesson was after I moved to WF about 8 years ago. Was using a 
pretty good collection of low dipoles and verticals and having some 
success. Then I put up a short tower (30 feet...in a rather snobby 
neighborhood and didn't want to rile the neighbors) and a TH3jr and was 
AMAZED at the difference. I really don't know why I was so surprised as 
I had learned the same lesson a dozen times over the years.

I know that is below the real minimium height to get such an antenna to play on 20. So here is my question-is it really worth the expense and effort to put a mini antenna at that height?  Would it show much improvement over a G5RV.  I know the G5RV has nulls in some directions, but I could fill those in with a rotatable dipole or a vertical as well.
