Looking for any pictures or engineering drawings for the tilt-over-post (TOP) for an old EZ-Way RBZ-75-3 crank up tower. This tilt base looks like a short section of lattice tower bolted to foundatio
Brian, Thanks for your thoughts. Yes, the tower is a three section beast, an Ez-Way model RBZ-75 to be exact, but it does not use the 'wonder pole' base. Ez-Way had two base choices for this tower, o
I use wire antennas here, stung up between tall trees. When not operating, the open wire feeders are disconnected from a remote tuner (mounted under the deck) and tied down in the yard 50 or more fee
I've read several suggestions that the coax shield should be bounded at the top AND at the bottom of the tower. This makes sense to me for all towers except crank-up towers. I would think that for a
I'm registered on the surplus site and sent a message asking why what looks like a commercial-off-the-shelf tower trailer had to be demilitarized (i.e. cut into scrap). I expected to hear the towers
Hello tower experts, I'm in the process of refurbishing an old EZ-Way crank-up and looking to replace some lift cable sheaves which have excessive wear in the ID of the groves. The current 3" OD meta
Here's a follow-up for those that might be reading this thread. Roger raises some good issues (repeated below). First of all, I don't intend to use nylon sheaves, but wanted to see if anyone had expe
Does anyone know if the TX-472 and HDX-555 both use the SAME #7 T-Base? If not, looking for the bolt pattern for a HDX-555. Thanks N3AE _______________________________________________ _______________
A local metal fab shop a few miles away told me they prefer tack welding rebar cages because wire-tied cages don't hold shape well in transit. Not sure I buy into that, particularly if diagonal braci
I'm trying to find out the proper way to attach two or three guy wires to the head of a screw-in earth anchor. I'm using Hubble Power Systems (AB Chance) PS816 "Triple Eye" anchors. The top the the e
I've been following this thread with interest. What's the proper way to bond galvanized steel anchor rods to the rebar cage to get a good Ufer ground? The UST specs specifically state not to weld the
I'd like to get the group's opinion on lightning protection for my new tower project. My property layout may be a bit different than most situations. I'll try to paint a picture. The tower base is 10
Bill, Everything I've read says you need to bond all grounding electrodes together. I think the electrical code requires this as well. If the tower took a direct strike, all the "earth" near the towe
Jim, Thanks for the feedback. Really appreciated. See my comments below. <There's a point of clarification needed here. Do you have one service, or two? That is, does the from the power company go fi
Unfortunately this thread has gotten way off the question I originally posted. Perhaps I should have posted a more pragmatic question: If I sustain lightning damage, what grounding and bonding config
The question of tying grounds together seems to come up often. I started a thread a few weeks back with a question on tower grounding which was hijacked into a spirited discussion on ground-to-neutra
I've always wondered about terminating coax shields on the top of a crank-up tower. On one hand, I think that by doing that, you're encouraging lightning currents to go down the coax shield as the re
I just passed the local electrical inspection for my tower a few weeks ago. Around here, it's rare that anyone pulls permits for amateur radio towers, so all of this was a bit new for the inspector.
One of the more interesting techniques I've seen to get a tilt-over "started" is the one Dave, G4HUP, has at his station. He uses a pneumatic bladder from some sort of truck suspension. It also has t
Hello fellow Towertalkers, Hopefully spring is around the corner and I can pick up work again on my tower project. I plan to make two 150 ft runs of LDF5-50A from the house SPG to the base of the tow
