I use a short vertical antenna that has a low feedpoint impedance.

Would there be any advantage to running two parallel 50 ohm coax to
reduce losses to the shack tuner?

If your antenna is 25+j0, paralleling two 50 ohm coax lines would
reduce the SWR from 2:1 to 1:1.

Is that what you want to know?

Yes, more or less. But, I wouldn't even bother trying to reduce a 2:1
unless the rig wouldn't tolerate it.

The antenna feedpoint impedance is around 20-j130 at 14 MHz,
approximately a 21:1 SWR.

Some years back there was a discussion on paralleled coax, and I seem to
recall that it wasn't considered to accomplish much even under ideal
conditions.


Oh. Well, then, it won't help. Are you opposed to putting an L and a C
up there at the base?
