Hi all, I found this line confusing....
"But then if you go insulated then do not run the feedline along it either or you just defeated the purpose of the insulated boom."
My question is if you run the coax along an insulated crossboom, ie. fiberglass, how could that affect the coupling of the transmission line when the object it is being attached to is "insulated"?

It all depends on how the elements are mounted.
If at 45 to 90 degrees from the crossarm, no propblem and use anything,
But if in the same plane then need insulated crossboom,
But then if you go insulated then do not run the feedline along it either or you just defeated the purpose of the insulated boom.

Is a fiber glass or some other non-conductive material necessary for a cross boom? What or the advantages and disadvantages versus a metal one?
