[TowerTalk] Tennadyne Plastic pieces

[john at kk9a.com]

I used a Tennadyne in St Croix once, I just did not recall a plastic mast bracket.  I believe it had a square boom so a polypropylene Stauff clamp could not be used to bolt the boom to an aluminum plate however maybe something similar can be made for the square shape.

Garolite is pretty tough and expensive. I have used it myself and it worked well.

With a log periodic hot boom you have to be careful how you run the coax across the boom but that's a different subject.

Yes, Dave is correct, the boom on the Tennadyne design is "RF hot" as to how the LPA elements are fed ...

Suspect something like Garolite or similar that W3LPL, K3LR, N4TZ/9, W9RE, and others use might be a suitable material?

Hope this helps!
