I'm working on plans for my 110' tower to be installed early this summer. Considering installing some thin wall PVC pipe inside one corner of the tower from near the bottom to the area at the top whe
Sounds like a great idea..except for the concept of having to "thread" the cable through the PVC ten feet at a time. One thing however, after living in FL which has high UV, I never saw any cable cra
I also agree with Bill. Good quality outdoor cable should not require this. CC Packet Cluster W0MU-1 W0MU.NET or 67.40.148.194 "A slip of the foot you may soon recover, but a slip of the tongue you m
I'm not sure that the LMR400 would need it, but I've done the exact same thing for other cables (rotator control, etc). I wouldn't use thin wall PVC, though ... it generally has horrible UV performan
You might want to consider the wind loading of the pipe vs cables ? I seem to recall seeing specs for towers that state the number of feed lines that can be attached to the tower legs. The wind l
Thin wall PVC is good for about a year in the Arizona sun. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA XZ0A VU7RG TX5C _______________________________________________ ______________________________
How are you going to support the coax going up the tower? Threaded through PVC you would only have support for the coax and control cables where they exit the PVC. I would prefer to support the cable
Agreed. Some cheap rotator cables will eventually harden, but I've seen even that stuff last 30 plus years. I'd think LMR-400 would be better off being taped or strapped to a tower leg every few feet
I have a number of coax and control cables hanging from my 106 ft crank up tower by Kellums grips. Seems to work fine. Rick N6RK _______________________________________________ ______________________
Most cables are fine up to about 200' hanging from a kellum or hoisting grip if they are protected from the wind, as they would be in a PVC tube, cellular monopole, or held laterally by crankup tower
I know it's handy and will work, but it's still a lot of strain on those cables. 73, Roger (K8RI) _______________________________________________ _______________________________________________ Tower
Not really. For example, 100' of LMR400 weighs 6.8 lbs. It's tensile strength is 160 lbs. Steve K8LX _______________________________________________ _______________________________________________ To
Are you sure? I buried some of that for my vertical and I thought it weighed substantially more than that. == JHR == _______________________________________________ __________________________________
