[TowerTalk] Help with Hygain TH11DX

[Steven Katz]

The TH11DX doesn't use traps on 12m or 20m, the driven elements are all part of the log periodic part of the beam, with elements connected by wire straps to the two phasing tubes.

So, I doubt it's a trap failure.  Sounds more like connections broke or worked loose on the 20m element and the 12m element.

How are all the "other" bands, like 15m, 17m, 10m?   Might help reveal if the problem is with one of the phasing tubes or its primary connection, or just with those two elements.

Sirs,
I have a TH11DX which has been working well for over 12 years with very good results.
Yesterday I lost 20m and 12 meters with very high swr....... almost infinity


On other bands I have 1.3:1 vswr with good performance.
I think it happened while tuning my amplifier using about 400w.
Wonder if their is a fix for the problem,its a real problem taking the antenna down ,my tower is Rohn 25g sections at 45ft.
Thanks in advance.
Aron Slonim 4x1fq.
