I think other folks have said this as well, but the answer is... if the supply
of the right kind of cable to do the job is
LMR and similar cables are not rated for low PIM
What exactly do you mean by PIM ?

What is the difference between real and un-real RG214? And what is the
problem with RG-142?

I believe that the real problem is that the center conductor is solid. A
slight nick in it will eventually cause it to break due to cable flexing
fatigue at the weak point. RG-400 is often used instead and has a stranded
center conductor.

What is the difference between real and un-real RG214?
There are some non-mil-spec RG214 varients out there. Sometimes they are
labeled as RG214 TYPE, or RG214 Commercial. These typically have double
braid like real RG214, but unlike real RG214, the braids are bare copper
instead of
The cables in duplexers are not under movement so the nick would not be the
issue there. The nick does expose the steel which is a ferro-magnetic material
that will cause intermodulation to occur at a much higher level. Plus, the
insertion loss will increase at that point and if there is a lot

OK Guys
My two dollar question is:
How to determine whether the braids are silver or tin coated,
without taking into consideration the brand/name on the sheath,
or have I missed the fine print in this discussion? :)

Hi Laryn,
Another war story also told over here some time back. One UHF box
we have in service went numb after about 3 months. Checked everything
out to spec... even the feedline looked good on fwd and reflected power.
After a lot of head scratching...
We replaced the 4 month old LMR-400
