>Bob - Telex /Hy-gain Sells the parts to convert the TH6 to a TH7 and
at one time Sold a Kit to do just that. So if a properly converted TH6
antenna is a TH7 then they would be equal ( conversion requires changes iin
the placement of the driven Elements and the moving of one of the 10 meter
elements. I looked at converting my TH6DXX to a TH7DX and in the end chose
to leave it as a TH6
as the existing band width and gain figures meet my needs.
For further information I suggest you contact Telex Hy-gain for the
conversion manual # 392S

I have done the same thing too. Converted a TH6 to a TH7. Worked slick,
but just gave me wider bandwidth. The beam worked the same of course.
Hygain doesn't offer this upgrade anymore because it isn't cost effective.
I purchased my upgrade for $139 back in 1983. I checked last year and the
cost was over $700. What's the point? Buy a new one. Gain stays the same.
I think Hygain did this to satisfy the solid state rigs. Then, someone had
a bright idea to put a tuner in the solid state rig. No need for that kind
of antenna. Works slick, but doesn't give you more gain.
I have a TH6 which I will match with any TH7 or KT34XA. I also have a TA33
which is a great little yagi for what it is.
