Subject: Re: [TowerTalk] LMR600 male DIN
I've said it many times, I used to feel like you toward connectors,
until a direct lightning strike to the top of my tower removed all of
the weatherproofing and 15 minutes later I had water running out of my
rig onto the desk top. It didn't hurt the rig, but it ruined the desk
top. 40 years total at 3 locations with nary a problem, but one strike
ruined 200 feet of 9913, IIRC 8 connectors, and a desk top
If you are on HF, Unless it is a long line, or you consider the legal
limit as QRP, as far as I can see, there is little to be gained from
using these expensive cables
I found 1/2" Heliax too fragile for kinking, or being stepped on. I gave
away two 100' runs with connectors. and went to LMR600. Now if I could
have found 7/8ths Heliax at a reasonable price, I would have used it for
VHF and UHF. The only time I saw a good price was a pick up load for
the repeater that was free free, but none as an individual.
Total length from my rigs to the top of the tower was 200 feet with
rotator loops and 28' pigtails to the antennas
73

## RFS 1/2 inch heliax is $1.48 ft from davis RF.
LMR-600 from davis is $1.69 ft
RFS 7/8 inch heliax is $2.89 ft
LMR-600UF is $2.81 ft
The above is all from davis rf website. You are probably correct though, for
runs of say 200 ft in total, or less, LMR-600DB + UHF male connectors is
plenty good enough for most applications.
If folks are going to use 7/8 inch heliax, dont mess with type N or
UHF...use only
7-16 din. Andrew doesnt make uhf for 7/8 heliax, but others do.
