What I did on my TH-6DXX's was split the difference between high phone and
low phone. I have a acceptable >2:1 swr over the whole phone band on 10 15
I don't know what it did to the gain on the antenna and I wouldn't know
how to measure it ( I'm not an antenna guru not you :-) ) but it looks good
on the antenna analyzer (MFJ 259B). I will have to let you know how it works
after I get all the rest on the coax and control lines run to the shack.

Since posting Roger Cox's enhanced TH7 dimensions,
I've received a few inquiries about TH6 performance so
here is my response to that question.
The TH6 manual has dimensions for CW, LOW PHONE,
and HIGH PHONE so it can be peaked in the desired protion
of the band.
The TH7 was designed to cover ALL of 10M which resulted
in the 3 dB gain slope that has maximum gain at 29.7 MHz
using the standard dimensions.
