[TowerTalk] Replacing coax question

[Tom Martin]

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?
