Dear Colleagues, From the top of my 72' tower I will have some 10 coax lines coursing downward from antennas. I remember a discussion about a type of coax sleeve or holder that works on the Chinese-F
The originals are called Kellem Grips or simply Kellems, but there are various clones around. I have found them at Crescent Electric (not in every US state, but locations all over the place), also at
Can't you do the same thing with some soft rope and a couple of clove hitches, and save $17? Saul K2XA -- Original Message -- From: "Alan NV8A" <nv8a@att.net> To: "Dr M J DiGirolamo" <DrD@2020.com> C
They're called "Kellums Grips". Available from any electrical supplier and some ham suppliers. Allen Ross Brier, N5XZ SET BriTech Systems Incorporated NICET Fire Alarm Level IV NICET Sp. Hazards / Sp
Kellums Grips work very well on a tower; however, the inexpensive (and more common) galvanized grips have a limited life when used outdoors. The galvanized Kellums grips failed on my towers after ten
Yes, high quality rope (e.g., dacron) serves the purpose very well and at much lower cost. Dacron will survive much longer than galvanized Kellums grips. 73 Frank W3LPL ______________________________
Sure. but the rope will rot, and it's hard to control the forces the rope puts on the cable, which will change with temperature, humidity, and age. The Kellems style grips grab all the way around the
It always astonishes me that hams as a class are so focused on saving a few bucks. Usually, there is exactly *one* way to do something right and that way may not be the least expensive way but it wil

Dear TTs; I'm sure there is a limit to how much coax may hang from one point on the coax, before the weight or wind overstresses the coax and either breaks it or alters its characteristics. I expect

I wasn't aware of Kellems, but I'd have used them if I had known of them. I see that you have to run the cables through them before connectors are installed. I used a gray (2"?) PVC 90-degree sweep t

Hi All! It really depends on your maintenance profile, initial costs, lifespan of the antenna system and the like as to which way to go. Kellems are nice, but Dacron rope can be quite acceptable in m
There is a class of stainless cable hoisting grips that are similar to the Kellems, but they are open on the side, and you lace them up around the cable(s) with a provided stainless braided cable (ab
Found some data in a Times Microwave catalog. LMR400 (and Commscope WBC-400 is similar) is rated with a tensile strength of 160 lbs, and weighs 0.068 lb/ft. RG-213 style coaxes run about 0.11 lb/ft,
Many thanks, Jim; Your calculations and experience appear quite conclusive. We don't need to worry too much about the weight of common coax overloading the tensile strength when it is supported at a

I went to college in Northern NY and I think the ice storm of '98 deposited about 3 inches of radial ice on everything that stayed in the air long enough to gather that much ... That would be 3200lb
