Hello all. Can't find the rules for TT, and I don't recall whether or not it's OK to post WTB requests. Hope I don't offend anyone with this: I'm looking for connectors for 1-5/8" hardline (RFS Cable
I just got three Green Heron controllers for my TIC rings. The rings aren't up yet, so I reconfigured one of the controllers to run one of my T2X rotors. The Green Heron design is terrific. It's a mu
Hi. I'm putting up 110' of Rohn 55G and I'm getting ready to dig holes for the GAC3455 anchors. The anchor installation drawings in the Rohn catalog don't give a specific angle for the rod. It appear
Hi. I need to buy some professional-grade heavy-duty come-alongs for my tower project -- tramming antennas, tensioning guys, etc. What brand/model/supplier do the folks on Tower Talk recommend? 73, D
The time has come to dig holes for my 110' of Rohn 55. Mindful of the Rohn specification to pour against undisturbed earth, and not wanting to get into the business of building forms and backfilling,
Here's another set of questions on "standard" practices: On a Rohn 25/45/55 tower, is it standard practice to run hardline, coax and control cables up the tower legs inside the tower or outside? Does
I don't have any comment on what to do about the guy bracket, but I was intrigued by the photo showing a shackle between the guy grip and bracket link. It was also interesting to see a bit of wire b
I got some interesting replies to my comment about Rohn tower bolts: "nope, heads have been on the outside and nuts inside of every tower I have put up, or taken down from others." "Golly, did Rohn s
Oops. Hit "Send" too quickly on this one. The full text is below. I don't see a drawing like that in my Rohn catalog, which is a recent but pre-Radian version that's pretty-much identical to the onli
Aha! That phrasing rings a bell. I knew I'd seen something about this in writing somewhere. Check out page 33 of the 3rd edition of "Tower Climbing Safety and Rescue", available from ARRL. It talks
In my experience (MADP-770/MARB-770), the antenna will be more of a determining factor than the MA-550. When the tower is properly installed, you can turn the tube easily with one hand, much like a s
Reviewing the Rohn parts list for a 110? 55G tower @90-100MPH, I decided to go with ¼? EHS for all three levels (actually, 6700lb Phillystran with ¼? EHS leaders. Following the parts li
Nice pics. The shots of the philly terminations are helpful. So, if shackles are required to mate the specified 3/8" thimble with the specified 1/2"x12 turnbuckle, why doesn't Rohn put shackles in th
Frank, Glad you weighed in on this. I got 1/2" thimbles for the Preformed Grips I'm using with the 6700 lb Phillystran -- as specified on the Texas Towers website. So far, so good. But I ordered 3/8"
If you relocate the capacitor to the tower, it frees up two conductors which can be wired in parallel with the brake and ground return wires. _______________________________________________ _________
Gerald, Thanks for the clarification on the Big Grips. Very helpful. I'm happy to stick with the Rohn/Radian spec. The Rohn 3/8" heavy-duty thimbles I have don't appear to need the legs spread to go
