Okay to start out "LMR" is a trademark for Times Microwave coax products, most other coax is designated as "RG" .The "400" is what they use as a size reference and is short for .405 in diameter which is the same size as an RG8, RG213, RG214, etc. coax.
I like LMR coax for it's quality. The solid core is really stiff and has a composite core of copper cladded aluminum, the super flex is stranded copper. I use 400 for my long runs up to 100/120ft and the 240 as short jumpers in the radio room.
The best bang for the buck is to get a quality RG coax for the length you need, look at the rating and the percentage of shielding, velocity isn't that important if using it under 30mhz.

The foam polyurethane is wrapped in foil 100% but the actual braid is only 85 or 90%. Certain brands of RG213 is 97% copper braid.

Ok then im thinking of making or buying some really good jumpers to get rid of some of the RF i got going on in my shack. i have to place my radio equipment just right or stuff squeals. I installed some grounding and it helped quite a bit but it got me thinking of better coax. I have far-rite beads on everything

I found some ABR Industries coax, RG8X size, that I have been making jumpers out of, surprisingly easier to install connectors compared to Times Microwave. The TM foil seems to adhere to the foam insulation, the ABR peels back easily. both have the same specs and both are made in the USA.

I used RG-213 for my rig. Very nice stuff - and not as stiff as LMR-400.
