The TH7 does have an additional element on 10mtrs, for a total of 5 elements
on that band. The "7" was also broader on 10mtrs. The beta tube with the
crossing or shorting strap I think was another difference on the "7". I had
both up at one time or another and definitely liked the Th7 more. ...my two
cents... - Mike, K4CVL

Bill,
When I asked my local dealer a number of years back he said the upgrade kit
is no longer available. So perhaps the Hy-Gain people are giving you prices
for replacement bits and pieces that understandably would cost more than the
original kit.
At my station, I have both the TH6 (56 Ft) and TH7 (72 Ft) and personally on
the s-meter and I see little difference between the two most of the time.
Both antennas are well designed, the TH6 being up over 20 years needs a
couple of 10 meter parasitic tips replaced.
My vote would be stay with what you have and put the money into low loss
cable or other toys for the shack. Or if you wife is anything like mine she
will find use for the leftover cash.
