As I am getting closer to having the new tower and antennas go up, questions
that I have never considered in the past keep on coming up. One of them is the
choice of coax.
As the title suggests, I am trying to decide between LMR400 and BuryFlex. I
estimate that I will need a total of 1000' to connect all 4 beams, the phasing
lines, 2 cables to the shack, etc. The max distance between an antenna and the
shack will be less than 300' (or 0.3db loss).
I like the LMR400 option due to its lower cale loss and cost. However, I
don't understand the practical impact of the fact that LMR400 is NOT
non-contaminating- is there going to be any impact from bundling cables,
attaching them to the tower legs, etc.? The cables will go in a PVC conduit
between the tower and the shack.
I do recognize the difference in flexibility (and its applicability to
rotating antennas) and my solution is to have a 10' BuryFlex attached to each
yagi, followed by whatever length of LMR400. I have to install Polyphaser coax
in-line protectors anyway and I will install them between the 10' BuryFlex and
Any thoughts? The difference in cost is about $150 at 1000'
