I would use a single piece of Belden 8267 RG-213 for this. It's durable,
there would be fewer connections and it would have less that 0.5 dB loss.

Subject: [TowerTalk] Replacing coax question
I am replacing a 90' length of RG8 water damaged coax to my 40 meter beam.
I have LMR 400 for the main run up the tower but want to use a RG8 section
for the rotator loop. There are two ways to do this. First, a 14' section
of RG8 from the feed point of the beam with one PL259 and one barrel
connector to join the LMR. Secondly, a 10' section of LMR and PL259 to a
barrel connector and a 4' section of RG8 for the loop to join the LMR that
goes down 80' to the antenna relay box at the base of the tower. This
configuration would require 4 PL259's and two barrel connectors. I want to
avoid the many possible problem areas with the multiple connections. I
think that I have answered my own question but wasn't sure if adding that
much RG8 to the run would offset the benefit of the LMR 400. I suppose on
40 meters the loss would be negligible. Am I correct?
73,
Tom W8JWN
