Last time I checked, the Tram stuff was made in Taiwan. It's sold by lots
of CB distributors. The antennas are real crap but the coax is probably
good enough for 30mhz and down... The dielectric can migrate and also the
outer jacket tends to take a set in the way in which it was coiled from the
factory. It's not horrible, but I wouldn't use it in critical applications
such as VHF and up or on a tower feeding yagi's etc. There its worth
spending the money for the "good" stuff.

If I understand the context of this question, you've got a radio
dealer that only sells this VERY off-brand coax. I talked earlier
about junk connectors. There's also junk --no name coax. Private
label stuff, no one really knows the specs, where it came from,
what the Quality Control is.
At hamfests and flea markets, I see lots of glorified zip cord
(red/black power wire, speaker wire, etc.) that sure looks to me
as if it's mis-labeled as to conductor diameter. The insulation is
fat but the coppper isn't. They are sold by vendors who are, for
the most part, CB shops, and the owners/salesmen don't appear to
be hams. I'd bet the coax they sell is at least as questionable.
Avoid these dealers and their garbage. Stick with good vendors and
good mfrs. The REAL mfrs of coax suitable for transmitting are
Belden, Times, Commscope. A few better ham vendors may buy good
stuff built to their own specs from factories like this and
private label it. I'd like to beleive that The Wireman, Davis RF,
and Pasternak are in that category. I bought a spool of some good-
looking RG6 with Pasternak's name on it that I suspect might have
come out of the Belden plant.
