I am putting up a second tower , but it will be about 200feet from the
shack and about 70feet high.
What coax is recommended to reduce loss to a minimum,and to feed a
multiband beam with a 2kw amplifier.
Hard line excepted due to cost.

I needed conventional low loss coax on the job a few years ago. Boss was
paying for it, so I was not pinching pennies. Best I could find was the
Times LMR400. As I recall, the center conductor is #9; so, it may not fit
some brands of N connectors. Unlike the 9913, this will not soak up water.
The loss at 50 MHz is 0.9 db, vs 1.6 db for 213 (100 feet). I know you want
20 meters, but 50 MHz is the lowest frequency I have any numbers for.
LMR400: 300' at 14.2MHz with VSWR=1.5, loss~=1.5dB
