Also, Im told from Hy-Gain, they never used the spring in the centre of
the top section (positive pull down tensioner?). I looked up some images of
the Tristao's and your right, the bracing is different.
Everyone seems to agree it has the bracing of the Hy-Gain as well as the way
top sections sit rested. But it has a Tri-Ex which, positive pull down
system, tilt over hinges and base mounting feet.
It seems the most likely option is its just a well modified hy-bread
Hy-Gain. Skip, KJ6Y, is going to pick it up and move it for me so I will
have his first hand opinion on the tower and condition. The seller is very
nice and is willing to void the deal if there is something wrong.
