Is there something special about Houston?

I doubt it.

Quad shield is a waste of time and money over good quality foil and
braid cables like Belden duofoil.

My experience over thousands of F connectors is the exact opposite.

Please post a link to a bad SNS connector. I have yet to see one when
installed to specification.

It isn't bad practice for his application. You obviously have not been
around many ham shacks.

Since he is running both TX and RX through the conduit and has some nice
receivers he would be aware of signal leakage.

The point is that in a much more extreme RF environment foil and braid
cables work fine.

Who to believe?

A licensed Radio Amateur with actual RF experience or some no-name that
can "see" signal leakage and prefers a termination technology that is no
longer used in the industry.

I think I'll stick with Mr. Halstead.
