[TowerTalk] LMR 900 Question

I want to get more of my xmt signal out to the antenna field,  and
have been thinking about replacing my run of LMR 400 with
LMR 900 -- it is a lot more expensive than what the 400
cost,  but also is a lot lower loss.  At $3.76 per foot for
around 165 feet run,  is this the best way for me to pick
up10% more xmit signal on 20M,  and 12% more on 15M??
These are the efficiency increases over LMR 400 per the
Times Microwave web site cable calculator,  see:


LMR1200 would pick up only 2% more eff.  over the 900,
and is much more costly!!  And how about LMR1700
at over $7 per foot!

LMR 900 is 0.87 inch diameter;  LMR1200,  1.2"

Show my ignorance about these some more:  are these
considered "hard line"  or just lower loss coax??

Thanks for any comments,

73,  Jim,  KH7M
