Doubling the number of feedlines would double the losses. Not only that

How can that be? Each line carries half the power.

Connector loss at 14MHz is insignificant.


Increasing the coax diameter would effectively reduce the loss.


No argument here. Except that it costs much more.


Matching the antenna won't make the Return Loss go away but it will make
the transmitter happy.


Maybe you are working from the assumption that a mismatch between the
source and line causes return loss. It does not. Only the mismatch
between the load and line causes return loss.

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?
