Regarding LMR400UF: I was also told about its negative features outside for
long periods.....after putting up four runs. Not worried, though, because I
encased them in "SPLIT-LOOM" spelling? That's the corrugated split plastic
tubing you see in automotive engine compartments to protect the wiring. I
did this so the wires would not get caught on the US Tower's stamdoffs. I
had had the experience of my Siamese and cat5e getting caught and ripping
when raising the tower. This prevents it. Hopefully it will keep the UF in
good shape. Next run up a tower will be DAVIS BURYFLEX.

So, what do you think is best? RG-213???
I think getting 5 years out of low loss coax is acceptable. I can help force
at least that interval of mainten ance on one's amtennas.

I have seen many glowing reports about Davis Bury-Flex for this purpose on
this reflector. No first-hand experience with it though.

I purchased a 500 foot roll of Davis BuryFlex(TM) Although not quite as
quite flexible as the LMR Ultra Flex, it is still quite flexible and has a
very rugged and slippery jacket.
I also have about 500 feet of LMR-600UF for UHF and VHF where I was willing
to settle for the shorter life. I also use regular LMR-600 for feed lines
that do not require the greater flexibility and on 160 for lower IR losses
although it probably doesn't make much difference.

I've had Buryflex in my rotator loop for 13 years with no issues. Great
cable.
