I am replacing a 90' length of RG8 water damaged coax to my 40 meter beam. I have LMR 400 for the main run up the tower but want to use a RG8 section for the rotator loop. There are two ways to do th
Should be VERY negligible. I'd ground the coax barrels at the top and bottom of the tower to provide lightning protection too, while I was at it. 73, Joe WDØM At 12:36 PM 10/11/2004, Tom Marti
There are still more possibilities. One is to use LMR-400 flex all the way. It would still have less loss than regular or foam RG-8. The flex version of LMR-400 is about the same loss as 9913 and it
I would use a single piece of Belden 8267 RG-213 for this. It's durable, there would be fewer connections and it would have less that 0.5 dB loss. I am replacing a 90' length of RG8 water damaged coa
I think I'd be more worried about moisture getting into the PL-259 / barrel connection splice hanging out in the open than insertion loss. Tom Martin wrote: I am replacing a 90' length of RG8 water d
I agree. Please correct me if I am wrong but I believe RG-213 is flexible enough to use for the rotation loop at the beam as well as where it would loop on the side of the tower when you crank it up
I have decided to run the LMR from the beam directly to the relay box at the bottom of the tower. The LMR is flexible enough for a large loop. It might get a little stiff this winter when the temps g
Why not use a single piece of LMR-400 flex? It'd have still less loss and I believe it's cheaper than 213. As for splices, I use the flooded heat shrink and have not had any failures (leaks) so far.
I think you will be making a mistake. Use flexible center conductor for the antenna to tower run, or you will likely suffer a failure somewhere, sometime in the near future. Keith NM5G --Original Mes
It does seem that LMR-400 may be an overkill for 40 meters. RG213 is very durable and certainly suitable for this application. Good luck. Bob W7KD Weather Stations", and lot's more. Call Toll Free, 1
Roger, I have the LMR in hand and will not buy anymore coax this year. I'm saving my dough for a DX-pedition for the ARRL DX test in March. I have FINALLY decided to run 213 to the LMR. One bulkhead
meters. RG213 is very luck. I feel like a mobile. I use 213 on ten meters, and only use 400 on six meters. _______________________________________________ See: http://www.mscomputer.com for "Self Su
