" A circular hole of adequate size actually requires MORE concrete than a square hole of adequate size. " I believe this is NOT true of the Rohn literature for '25 73 John
Heat is the key. I bought a mondo iron (the tip is about as big around as a little finger) for $1 at a garage sale. It works perfectly and takes forever to warm up. It also takes forever to cool down
Hi Steve, I guess there's four categories of PL259 bodiesI've run into: 1) Silver plate (no prep required) 2) Plated brass (usually requires no filing/scuffing to achieve a good joint) 3) Plated bras
I can't see where the type of anchor is shown on this page but the hardware (turnbuckles) used in that installation look like $5 Lowes units, not what I'd expect to guy a 180' tower. There's a world
I was looking through an older "hints and kinks" mag from the ARRL and I noted there was an article in there with a mod to the A3 which involved adding the 40m extention kit(s) to the original direct
...the article indicates that the author added the 40m extention kit NOT to the original driven element, but to the original director and reflectors. This of course requires TWO kits to accomplish. S
In reading some of the Cushcraft comments, I thought to add my .02$. I needed a set of trap seals from them for my A4S and filled out the form on their web page. I got a reply the next day listing pr
I use one lanyard around the tower, and one that's always clipped to two rungs above me on one end, and a d-ring on my belt on the other. When I reach the working height the one around the tower gets
While there may well be better ways to keep one's self from falling off a tower, I don't believe that a 2-3 foot fall ("several feet") is enough to routinely kill someone. Consider a seatbelt, which
Sounds like a small conductive jumper (strap/braid) attached via the bolts holding the sections together might solve this issue in short order! 73 John wb5oau
Kris mentions: ""Yes, but for how much longer? Just because it can be done doesn't mean it's safe or permanent by any means. If the tower fell, causing measurable property insurance, would the insura
Carl mentions: I've had the same experience, except my run was about 70'. There's about a 2' slope from one end of the other, and at the LOW end, rather than just installing an elbow (or sweep) to br
If you look at the numbers in the Rohn catalog regarding "pull out requirements" (I forget the correct nomenclature) you'll see that AB Chance supplies a commercial unit that far exceeds that of the
I'm working on the ground field of my new towerette (40' Rohn 25). The tower is guyed and is about 70 feet from my house, and the radio room (2nd floor shack). Following some of the dialog here and t
As of six weeks ago when I bought my Hazer, GME paid freight on most all of their items (more correctly, the freight charge was buried in your items purchase price). John
Can anyone provide any first hand information regarding the Cushcraft add-on for the A4S and A3 antennas? A rotatable dipole for 40M sounds great, but I dont want to auger the performance of the rest
Well, Coilcraft sure didnt make it practical to rebuild traps on ANY antenna. I just took 12 traps apart (a4s+40) and it's nigh on impossible to reform the brittle aluminum formed area where the (rus
The Coilcraft issue we're having at work bled over into my posting about Cushcraft trap construction. Sorry for the brain spasm! John wb5oau/4 PS: Thanks Tom! :-)
I wrote Polyphaser and ICE and both indicated that they do not manufacture a HF/KW rated surge supressor for coax, that passes DC (for coax switch control). I guess I'm going to have to pull some cab
