My old gray matter is not 100% recall on an article in QST or CQ regarding
connector loss. The tester uses a spectrum analyzer and a TDR with other lab
equptement.
He had up to 20 barrels ,T. and Pl259’s with short lengths of coax .
And the findings were that @ HF and insertion loss was minimal and the BIGEST
issue was lossy CABLE

Subject: Re: [TowerTalk] How many connectors?
I have a lot more connectors than that and my station is quite loud. Use
a quality connector such as Amphenol or Andrew/Commscope and don't believe
the old wives tale of PL-259 loss. Also use the best feedline that you can
afford.

This may have been asked before, but I am cleaning up my system from
temporary to permanent installation and I was thinking about putting in a
patch panel. My question is what is a reasonable number of connectors and
barrel connectors to have between antenna and amplifier. For now the
antennas go directly to the amp but I'm adding antennas and was going to
neaten things up with a patch panel so that I would have;
1. Connector at antenna
2. In/out connectors through lightning protection in junction box
outside the house
3. Patch panel inside house on other side of wall which would have
1-barrel through panel, connect on backside and on frontside
4. Then a connector to the amp or possible a switch (which would add
two additional connectors)
Is there a rule of thumb for any of this? Thanks.
