Hi Guys,
83-1SP is the top of line, aged old, Amphenol PL 259. SIlver body, pin and
barrel, but one key point is that it uses Teflon dielectric. Teflon is the
best connector dielectric in terms of its high
resistance to soldering heat as well as its durometer (related to density) is
best for moisture resistance. However, as you all know, moisture in connectors
is a no-no, so sealing the connector from the cable and up over and on to the
SO 239 (over the SO 239 threads) is paramount. Lot of historical advice on TT
for sealing. Just be sure to go over what you use for sealer with a highly UV
resistant tape as the last outer coat . All of this relative to outdoor use.
The RFX version of 83-1SP is less expensive plating (nickel) and uses the
less expensive phenolic dielectric which can be big problems when a little too
much heat is used in soldering.
Key words with any connectors: avoid phenolic. Silver plating is excellent
but either one, moisture protection is a must.
You don't need to spend the extra $ for Amphenol for excellent mechanical and
electrical integrity. RF Indusrtries provides excellent connectors which I
have sold and used for over 25 years without a hitch. They are made in Taiwan
by a well QC'd mfr. vs. any I know of from mainland China. I am fairly sure
that production of Amphenol 83-1SP''s
are built in France, Mexico, and USA. I will check on that Monday and if
incorrect I will let you know.
