Yep, what Jim said.

RG174 would even be usable on 160m, not great but useable. The beverages I
built for XA5T were fed with a couple 100 feet of RG58. We only had to listen
to the US so a NE and NW antenna were used. They worked great on 160M and 80M
and we even used them on the higher bands to help split out the pileups since
our beams were not rotatable. Switching from NW to NE made the W7s go away and
the W1s pop right up.
I would just bite the bullet on the extra coax and run it through your access
patch panel and not worry about the loss. You could always run two runs and
swap the cables and see if you can tell the difference as an experiment but I
am doubting it would be noticeable.

Beverage loss on any reasonable rg6 is near zero on low bands.

I have a question concerning feedline runs which I'd like to present to
the group.
I have four beverages with the feeds on one side (front) of my property
and my tower and other
transmitting antennas on the other (back) side of my property with the
house in the middle. The coax
runs and control lines from the transmitting antennas come into the
house in the back where the utility
lines come in and everything is tied together there to the utilities'
ground, etc.
The problem is that if I bring the beverage feeds around to the back
where the transmitting coax, etc.
come in and bring them in there it will greatly increase the beverage
feed runs (probably by 150-200ft)
with the resultant increase in loss, etc. I would prefer if I could
bring in the beverage coax runs in via the
front of the house (close to the shack) but then, of course, they are
far from the utility/SPG ground. I do
have a run of grounded #2 tied to the utility ground running around most
of the house including the front.
Is there any good way of bringing the beverages in through the front or
should I just accept the longer runs
and bring them through the back with everything else?
Thank you in advance for any comments!
