QSL. My point was that Motorola, as a feedline vendor, supplies these
pieces of THHN with their cables thus giving their blessing to this type of
install. It's been my experience that generally Motorola sites are poor in
terms of installation techniques and standards. Some of them are pretty
crappy in fact.
In my commercial tower service experience, I've installed thousands of
the Microflect doughnuts along with angle or round member adapters as well as
wraplock and other methods. The hardware was typically dictated and supplied
by the customer so it was their choice.
I still think that for amateur use, the THHN is a viable cable attachment
method. It IS better than white tie wraps, cheap electrical tape or other
typical ham methods.
