added to a free standing tower, not an issue. How so? In a no wind static case, the guys add down force, some of which will appear on the diagonal cross braces. How much depends on the relative comp
You're right, the difference between 15" and 18" steps is kind of a big deal on taller towers. We work regularly on a couple of broadcast towers with 18" steps on the climbing ladder. One of them is
The rub is the insulated tower sections from ground. It can be done with fibreglass rods. Need a bucket truck or man lift to assemble. I'd be scared to climb a tower on 1.5'' fibreglass rods. But wi
You tune for minimum current in the skirt, at least the ones I've had my hands on. The tuner and RF sampler is connected between the skirt and ground. I've assumed that the skirt and tower become *on
bottom and top end..just to get their speakers to sound flat ? Nobody. And thats exactly what they do on their Flagship Bose 901..now series 6 speakers. Pointing 16 tiny speakers at a gyproc wall, a
I did exactly that, almost, around 1970. HDBX-48 extended to 72'. 1.5" water pipe made out of threaded 10' pieces and coupled with threaded couplers (spot welded). Short collars every 12' or so made
Seems like a perfect chance to cut off the anchor bolts, epoxy in new ones and put up a bigger tower. Course, the existing chunk of concrete may be undersized for a bigger tower... -Steve K8LX _____
I'm faced with this every so often in my work, and my go-to methods are: 1) 6' lever arm, which you tried, 2) cut off wheel in angle grinder, (already suggested) which is ultra fast and always works,
A guyed tower can be designed for closer guying than that, no problem. Takes more steel, bigger guys, bigger anchors, and careful engineering. There's a 1000' TV tower near me with outer anchors at a
I have never seen Amphenol right angle UHF connectors, however I do have several male - female right angle UHF adaptors. The part number is 83-1AP (UG-646/U). I have only used them occasionally but
A connector gets *installed* (relatively permanently, to a cable or panel). An adapter does not. I have adapters I use just like connectors. UHF to N is quite common. Yes, but you're using them as a
Depends on the soil and the size of the anchor. I've had 200' of 45G guyed for 30 years with *big* screw-in anchors. The soil is heavy clay and gravel mix, and when we installed them there was no dou
It's perfectly feasible, but depending on your plan for handling the guy wires, may not save all that much time over dropping the mast with antennas into a short larger pipe stuck in the ground, drop
Rich, I'd like to offer one slight modification to my aforementioned alternate method, not because there's anything inherently wrong with hanging a whole tower from a crane, I've done that many times
Working a lot of countries is no indication of an antenna's performance. Right. Over a period of a year or so, I have 125 countries worked QRP. N6BT has often talked about working all continents in
my question is about which is TECHNICALLY the best option, if there is a technical benefit or about RFI to put them under ground. If there's no advantage, is much easier to manage the cables OVER th
We are planning to remodel our home. After the remodel, my crankup tower will no longer be capable of tilting over. I have never tilted the tower over since installing it and have no plans to do so
I have a piece of Andrew 7/8" hardline with an Andrew 45J connector on the end of it. I am not familiar with this connector. What type of connector is it? And what type of connector would I need to
I'm not familiar with a 45J. Andrew connectors with a "45" are usually for either 5/8" Heliax or special splice connectors for 7/8". If it's brass colored, it's an old series connector and definitel
Can anyone refer me to a Dummy's guide to welding rebar? 1. I have heard that I have to use special weldable rebar. What do I ask for? I'm assuming that the common rebar at Home Depot, etc is not it
