This is good 50 ohm cable, though I wonder if they really have the long discontinued LDF5-50A. The $13 connector fits the RFS Cellflex 1/2" cable. Connectors for 7/8" are $30, still not bad.

I have used and am using LDF5-50A and LCF78-50 at HF through UHF though I am not sure mine is the 'JA' variety. LDF5-50A and the LCF78-50 I have are very similar except for a different type of foam being used for the dielectric. I have successfully spliced the two types of cable for the 375 foot run to my TH-11DX. Yes, this is probably overkill at HF, but I am an overkill kind of guy where possible. I *hate* losing valuable RF! ;)

Tim,

Got any responses on this yet ?
I am thinking of trying some 7/8" hard line from Davis RF.
It is their 7/8" RFS Cellflex.  The connectors aren't too expensive,
about $13.00.
Here's is their page for info.

Anyone have any experience with this stuff ?
I understand it is used a lot on cell towers.

Several years ago I was able to get about 100 feet of 7/8" Hardline
from our local cable tv company as they were replacing it with heliax.

If it is useful for my tower rebuild, I would like to put it into
service there.  The question of matching and connectors rears its ugly
head.  Again realizing that I am probably about to start a firestorm,
I am asking for input / suggestions

Thanks
