As far as hf goes, jumper length isn't a problem at all. The swr on the
jumper is close to 1 to 1 if the tuner is working, so virtually no loss.
Ten feet or more isn't a thing to worry about. I used Larsen antennas for
years on uhf and they came with a 15 foot run of rg58 for mobile installs,
worked fine. I don't like rg8 for jumpers as it is too hard to flex, I
like either 8x or even 258, at the lengths and frequencies we're talking
about, loss is very very small.
The first antenna I put up when I got my general way back in 1968 was made
out of zip cord and a small metal box with an so 239 and insolated
terminals for the wire. I fed it with 70 feet or so of rg58. My rig at
the time was an hw 12 and it kicked butt on 75.
I bought an ldg tuner for the icom 718 I won a couple months ago, and I
have to replace or fix the jumper they included, one pl259 on it is
intermitant.
