Default Q about balanced feed line

I am also concerned that the feedline may be causing unbalance condition
because it is routed straight down perhaps 30 feet from the feedpoint
then it makes a sharp turn to the shack and at that point it is parallel
with one leg of the antenna for about 30 feet.


Hi Al,

Too much worry can come from too little problem. You need only ask
yourself does the line inappropriately inject receive signal from the
nulls of your antenna; or do you get RF in the shack? If neither are
a concern, there is certainly nothing worse to worry about.

It's the only way I can
do it. I have thought of discarding the multiband doublet for a plain
dipole with 52 ohm coax. I do like the doublet and my Johnson matchbox,
besides I can use this antenna on 160 when I route the feedline via a
knife switch over to my MN2700 and configure it to a inverted L.


Nothing here suggests you change anything.
