RG-142 inner conductor is also plated steel as all that of SAT coax is.
Sheet diameter of RG-304 is 7.1mm.

## It looks like 304 is .280 OD.... which Im sure is bigger than 8X
(.249)
It appears the center conductor on 304 is 1.5mm = .059 inch = 14.5 gauge
wire.
The center conductor consist of silver plated steel ! Solid too, not
stranded.
Never heard of silver plated steel being used b4.

Subject: [TowerTalk] RG-304 for CMC ?
Does anybody know anything about RG-304 ? Its aprx .271 OD.... and has
teflon + silver braids /center conductor.
Im having a helluva time trying to find out what gauge the center conductor
is. Does anybody know ?
I think 304 is sorta the teflon version of RG-8X, and aprx the same OD.
If you can wind RG-58 and also possibly RG-8X onto a stack of torroids,
then there should be no issue using RG-304.
IF 304 has a bigger center conductor than 303 /400 coax, then it might be
an excellent candidate for applications
where a high powered CMC is required. RG-393 is .392 OD.... slightly
less than the .405 found on 213-U.
I'm looking for a possible alternative to 393, but cant find any V rating,
power ratings or attenuation charts for 1-54 mhz...for 304 coax.
I have also looked at some of the plenum rated small coax, but the price is
sky high...and difficult to locate in small qty.
