Hi Mike,
I can't imagine that a few 100 feet of extra length would make any
discernable difference in signal loss - especially on low bands. There are
1000 ft feed lines (RG-6) on some of my Beverages and signal levels are fine
(actually quite good) from 160m to 20m. I think most important is to be
sure to reduce possibility of common mode on the coax. W8JI site has some
very good info on this.
Hope this info is of use to you.

Subject: [TowerTalk] Beverage Layout Problem
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!
Mike W2LO
