[Elecraft] Coax Loss Figures

[Brett Howard]

Thats another really great data point!  Knowing Cisco getting the word
ultra printed on the box cost a good chunk of extra change! ;)

Well heck if LMR400 is .7dB/100ft I'm not so sure that its worth mucking
with finding adapters for it as if I end up having to put 2 adapters on
each end to get it to something I can use there goes most of my
advantage of stepping up from LMR400 to LMR600...
