The bigest difference is in band width and weight 
Gain figures at the best point are almost identical
But if you like to move around a lot during a contest 
then the TH7 may give a slight edge on 10 M 

Also Telex Hygain will still sellyou the parts to convert a TH6 to a TH7
and the manual to do this but they dont sell it as a kit (Bummer) you 
have to buy each part seperatly ( a second driven element and a new 
matching network. You have to get a real good deal on the TH6 to 
justify doing it this way.
