needing to replace my rg58. is LMR-400 the new recommened coax these
days or rg6?

It's not possible to make a recommendation since you've not told us
anything about the application.

What frequencies do you want to monitor?

How long is the cable?

Why do you think the RG-58/U needs to be replaced?

RG-6/U is just a generic designation. There are many variants
including the ever popular but unnecessary quad shield. If you select
a particular brand and type number, Belden 9116 for example, it will
be possible to look up loss figures and do a comparison.

Besides being expensive LMR-400 is 10mm in diameter and not as easy to
work with as RG-6 or RG-58.




thanks. I was doing some research at scannermaster and saw LMR-400 and
RG-58, but didn't see RG-6. My current setup over 20 years old and living
in Iowa I would imagine it is close to its lifespan. Plus, when I chose
RG58 back then, I was under impression it was considered best cable for
the job. Probabably is a 40' run to the antenna (which will also be
replaced) which is about 30' high. Main interest here is mil air. I will
be splitting it to work on a Pro-2004 and BC250D. Which I realize will
introduce some loss. I am using a Radio shack amplifier to compensate for
some of the loss.
