On a related topic, I’ve stopped using LMR400 and LMR400UF coax completely for 
HF work, using instead trusty, old-time RG-213, with its untinned copper braid.

I've used a LOT of Commscope 3227 and their PTFE plenum equivalent. It's loss specs are the same as LMR400, solid #10 copper center, pretty dense tinned copper braid over Al foil. Both solder quite well. The PTFE plenum coax is smaller diameter, so I build it up with heat shrink before mounting the 83-1SP connectors.
