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

Single band or multi band?
How does the feed point change with frequency.
450 ladder line is the usual low loss wire used
for multi band systems.
But what do know, I've never put up a ham frequency antenna.
