Hi,
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:
http://www.timesmicrowave.com/cgi-bin/calculate
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
