Does that entail more than microphones? Do you repair equipment?
Engineer or build equipment?

Microphones, instrument packs, wireless intercoms, wireless in-ear
monitors, etc.

I do component level troubleshooting and repair.

I am not an engineer. I am a high-school "dropout". That being said,
I design and build RF amplifier systems, spec fixed filters and have
Anatech build them, and tune "agile" cavity bandpass filters. I sweep
cables. I coordinate frequencies for "live" TV shows.

That sounds like a great job. Good for you.

You probably use some kind of TDR to test the cables. Is most of it 75
ohm?

I've never worked with "agile cavity bandpass filters". Sounds
interesting.

Oh yeah. We currently use LMR400 UltraFlex, but I'm pushing to change
over to Davis Buryflex. All 50 Ohm.

Are you sure the Buryflex is a better cable you your application? The
attenuation per foot is a little higher. The Buryflex is not specified
to extent that the LMR-400 so I can't make a recommendation.

I would buy some as a trial to see how it holds up compared to what you
are using now.

The Buryflex cable does not have any specifications for bend radius for
instance or much at all for specifications compared to the LM-400.

What connectors do you use with this cable? N type?
