275 feet of garden variety RG8Foam would have a loss of about 1.5 db at
10
MHz. LMR400 about 1db. Do NOT use RG213.

What's wrong with RG213?

It has twice the loss.

I show it or regular rg-8 to have only about .2 db more loss per 100
ft than foam rg-8. "10 mhz" So 275 ft would be appx 2.1-2.2 or so db
vs the 1.5 db. I would consider twice the loss to be 3 db loss.
..6 db should be hardly noticable. MK
