Hi Skipp
The common white Teflon coax that I run across is RG-188. You are correct I
have never seen the part number on it but Teflon jackets do not take
printing well.
A fairly complete listing of Teflon coax cables is below
RG Number Belden Number Cable OD
RG-393 .390 50 Ohm, RG-8 size coax
RG-304/U .280 50 ohm
RG-141A/U 83241 .187 Single shield, 50 Ohm
RG-58 size coax
RG-142B/U 83242 .195 Double shielded,50 Ohm RG-58
size coax
RG-400/U .195 50 Ohm RG-58 size coax
RG-303/U 84303 .170 50 ohm
RG-180/U 83264 .141 50 ohm
RG-187A/U 83267 .111 50 ohm, White Teflon tape
jacket
RG-188A 83269 .108 50 ohm, White Teflon tape jacket
RG-179/U 83264 .100 75 ohm RG-174 size coax.
Very common for 75 ohm cabling
RG-316/U 84303,84316 .098 50 ohm,
RG-178B/U 83265 .071 50 ohm, Very small Teflon
coax
Thermax/sonic (http://www.thermaxcdt.com) is another large manufacturer of
Teflon coax cables.
RF parts has RG-316, 141, 142, 179
Also of interest for those making some types of power splitters and
combiners for solid state power amps
Communications Concepts (http://www.communications-concepts.com)
has 25 ohm coax DA25070, DA25090, Microdot D260-41180-0000.
Hopefully this will give you some options to chose from.
