[amsat-bb] Station advice: coax

[Keith E. Brandt, WD9GET]

There's been a lot of good station advice on the reflector recently that 
I've really appreciated. I'm slowly but surely building up my sat ground 
station. I've got my Yaesu G5400B connected and running and I've got an 
antenna plan. The next issue is running coax.

What's the recommendation on coax runs? It looks like I'll have between 
75 and 100 ft from the shack to the mount. I can envision running a 
separate line for 2m and 440, but is it also effective to use a diplexer 
at the antenna? Does that limit my ability to later add a mast-mounted 
preamp with power-over-coax? (I'll probably add preamp(s) at a later date)

Is the ultraflex coax really necessary for hooking up around the 
rotator? I'm sure it's better, but is it really worth the extra cost? I 
certainly don't want to pay the high price for ultraflex for the full 
run, especially if I'm using two lines.

Thoughts appreciated.

73,
Keith
