[TowerTalk] LM470 or HG-70HD or ?

[damon stewart]

Terry, W6RU thinks it looks allot like a Lou Tristao (pre US Tower) 72'
Tower.  Skip, KJ6Y also pointed out it cant be a Tri-Ex but it has features
that where not found on the Hy-Gain.  I sent photos to both Hy-Gain and to
Karl Tashjian and both say its not one of theirs.  When I looked over the
tower it does not look like anyone modified, it looks like this is how it
was built from the factory.

So maybe its a Tristao?
