Default Restoring a Hy-Gain Yagi...


"lagagnon" wrote in message

I am about to refurbish an old Hy-Gain TH3-Mk3 Thunderbird tri-band
yagi. This yagi has been used in a coastal environment and thus the
aluminum is slightly pitted and most of the connecting hardware needs
replacing.

I figure steel wool would work fine for the aluminum tubing, I know
how to test the traps, but I am wondering whether to use stainless
steel or galvanized hardware? Which would react least over time with
the aluminum? Also, I remember many years ago there is an electrical
joint compound stuff for using between the tubing sleeves - can anyone
please give me some brand names of this stuff?

Any other ideas appreciated....

When I refurbished my TH-66DX about 10 years ago I used the green
"synthetic" steel wool or scotchbrite material.
Worked great and no residue left over.
Between the elements when put back together I used "never seize". Worked
well and conducts RF and DC.
After ten years I have not had any changes in the performance or SWR on the
antenna.
