I've read that Davis Bury Flex is very good (low loss) coax. I have
Cable X-Perts RG-8 (50 feet of it) as my feedline right now. Is it
worth my time and $ making a change to Davis Bury Flex or something
similar?
Jeff:
You might ask yourself how much the loss differential would be between
the present cable and the proposed cable, for a length of 50 feet. You
can then decide whether the "dB per dollar" result makes sense, or not.
Evaluate the loss of the two cables at the highest frequency at which
you normally operate. My suspicion is that you will find the difference
is a fraction of a dB. Considering that even measuring power to an
accuracy of +/- 1 dB can be difficult without a decent wattmeter, you
might use that in evaluating the dB per dollar computation.
This assumes, of course, that your present cable is not defective.
