[TowerTalk] Skyhawk, KT36XA, opinions requested

[Robert G. Strickland]

Steven...

Thanks for this and your other direct message.

Another "issue" comes up that I have seen here and there on the reflector, 
but I'm still not sure about the answer.

I live in Syracuse NY, and we have our share of acid rain. It seems that 
both antennas - and others - make use of sliding aluminum tubing 
connections. What is to prevent oxidation of the connecting surfaces with 
resultant deterioration of RF performance? Can this deterioration, if 
present, be abated by using some sort of conductive joint compound during 
assembly?

Concerning the KT36XA, it seems that the elements are not spaced using the 
more modern element interleaving techniques based on computer modeling. On 
the other hand, the antenna clearly uses sophisticated element length 
adjustment using stub sections and, I imagine, capacity loading. It has a 
longer boom. So, does this represent "one way" of achieving optimum 
multi-band performance, or is the uniform spacing inferior by design to 
those tribanders using interleaved element spacing?

You can tell I'm new to yagis. About quads I can speak at some length <g>.

Thanks to all who are contributing to this thread. All comments have been 
most helpful. Great group.
