[TowerTalk] 7/8" CATV Hardline

[N1BUG]

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! ;)

73,
Paul N1BUG
