I'll do the climbing. I may no longer be willing to face away from the
tower in order to reach a loose bolt out on a boom 70m up & I
doubt I would be willing to do any of the things required to get
antennas up at W7RM (like dropping most guys on 50m of AB105
to winch up 140-150 kg of 40m monobander, meaning as you look
beneath you the tower is no longer there due to the deflection -
something I would only trust the late, great Rush Drake to do), but
if it wasn't clear, I don't see how BX-like anything can be extended
& loaded & still be safe.
If it was, then why bother going to anything more robust than BX-like
stuff for the majority of amateur installations? The late W7FU's 75m
KLM (4-el?) on 50m of 45G gave me the willies & one might argue that
the same technique could make it possible to do the same on 25G.
Where is my hack saw? It's the middle of the night here - I'll go
nick some Water Authority pipes & use them to fly a stack of TH6s on
the roof of my flat later this morning... ;^)
Per specs or pay the PE - or take your chances - no arguments here,
mate.
