Many PL259s have not been problematic for me. Good I/O
I recommend W6LGs youtube video:

He proves it...on camera.

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.

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.

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

"A db here and a db there and pretty soon you lose 3db"? to paraphrase
Everett Dirksen for those old enough to remember.? I built a spread
sheet of cable loss by band, amp out to antenna terminals, every foot of
every cable.? It seemed to me that good coax db's were cheap vs amp +
tower + antenna db's.? One size doesn't fit all, I use LDF5, LDF4,
Buryflex, and RG400.? Most every band has 3 of these 4.? Depends on band
and lengths and purpose.? My result < 1db loss every band for the
monobanders 80 > 10. ? Connectors (good ones) hardly matter except for
weather proofing and mechanical strength.? I use DINs for hardline for
several reasons other than lower loss.

I have 16 connectors in line for each antenna I use
In my system
Antenna to rf choke
Arrestor on the tower
Base of tower
Shack Entry Panel with arrestor
Coax switch
Amp
Band pass filter
Transceiver
Keep them dry use silver plated connectors
Water proof them, don?t rely on just tape !
Use good quality hardline and coax
Cheers!
