Hello. I am making good progress on my new (and first) tower.
I am connecting my RF signals to the Yagis on my new tower using 7/8”
Andrew Heliax. I would like to ground the top and bottom of the Heliax to
one of the galvanized legs of the tower.
I am concerned about putting 2 dissimilar metals together (i.e., the
corrugated shield of the Heliax and the galvanized steel leg of the tower).
What type of metal is used to make the outermost shield of Heliax?
And, do I need an intermediate metal (like stainless steel) between the
Heliax shield and the tower leg?
Thanks for your help.
