No I wish I did, that is in the works along with another 20 feet of tower. 

I went up and untied the second BALUN (coaxial current type) and that seemed
to improve it somewhat. I think the next thing I will do is snip some coax
off and see what that does. The pigtail that I made up for the th6 is longer
than the one I had on the Hornet so that may be causing some trouble not
sure yet though.
