I use "alumslip" (I thinks it´s a product from the U.K.) on he joints of my
yagis.
Thats a kind of grease mixed with very fine aluminum powder.
After mounting and aligment I put a double layer of sef vulcanizing tape
across the joint and cover all with heat shrinking tubes.
Never had any trouble with dismounting those parts.

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.
