[NLRS] Need advice on use of LMR-400 with rotor

[vhfrover at aol.com]

 Hi Dave,
   I use a 25 foot lengths of LMR400 with the solid center conductor on my rover for 902 and 1296.  the antennas are mounted on a 25 foot push up pole that I rotate by hand.  So far no problems.  Note that I only use this setup 6 times a year (during the January, June, August and Sept ARRL Contests and for the uWave Sprints in the Spring and Fall).  With the long length, there appears to be little stress on the line as it twists 360 degrees.  A shorter length will see more stress as you rotate.
Best of luck,
Mike WB8BZK/R

I'm thinking hard about my rover set-up for the upcoming contest in June.  I
have a big spool of LMR400 with the solid center conductor (i.e., not the
superflex).  Do you think it's okay to go ahead and use this in the rover
set-up with a rotor?  I've read some mixed reviews about using this cable
with a rotor--some say it's fine and they've had it up for years, others say
the center conductor isn't meant for that sort of flexing.  My inclination
is to say that, at the very least, for something that is going to be used
for a couple of days at a time, three or four times a year, it's probably
okay.

Any rovers out there with advice?  I hate to buy more cable if this will
suffice.

Thanks and 73,

David  W9HQ
