[TowerTalk] [Bulk] [WARNING: A/V UNSCANNABLE]Teflon 50-ohm coax

[Grant Saviers]

Probably RG142.  Be aware that designation has several implementations, 
although I think the MIL17/60 is "silver coated copper clad steel" 
center conductor and "double silver coated braid" shield, tan TFE jacket 
and TFE insulation.  The spool I have is genuine MIL.    Generally, 
specs say it is good for QRO power levels to 50MHz.  I use it for 
winding coax chokes on FT240 cores, which pushes it a bit on the minimum 
bend radius spec but haven't had any problems QRO to 30MHz.

I would not say it is "supple" with the SCCCS center wire and double 
braid.  Be cautious since I've seen cable marked RG142 with single 
tinned braid  and TFE insulation.  New stock is $3 to $7 per foot. I've 
seen it go on ebay for $1 per foot in a 380' spool.  There are several 
listings on now around $1.50/ft and they look like the real MIL17/60 RG142.
