Andrews LDF4:
Any thought, comments about L4TNF-PS vs L4PNF-RC? -RC is a captivated
pin connector which is gold and silver, the other connector is bronze
inner, trimetal housing.
I'm thinking that the less potential metal interaction, the longer the
coax will last.
I've also seen Trilogy listed in the same transmission line category,
which uses a solid aluminum tube for an outer connector and a solid
copper tube for the inner connector. The only issue I see there is the
thermal expansion coefficient, or how much is my cable gonna grow from
cold to warm days? This needs to last a decade.
Station is not duplex, (originally quoted as LMR-600), but since the
install needs to last a decade, I need good stuff.
