Many thanks to W0AW and N7ML who suggested that I double-check the phasing of my stacked yagis. I was working on the ring rotator, and re-checked the lower feedpoint. The antennas are direct-fed with
You might try the local utility supplier. Beware however that not all steel rope wire is EHS. Make sure you get the EHS (Extra High Strength) stuff. Anything that is forged and hot-dipped-galvanized
I'm stacking a pair of large tribanders (7el 24ft boom) at 60' & 100' on Rohn 25. The lower one is on a TIC ring. No problems so far. I have a friend who has pair of 6el 26ft boom tribanders plus a 4
Most carabiners are not rated for fall arrest. Unless yours is, I wouldn't use it as a life-saving device. Also, be sure your front D-ring is rated for fall-arrest as well if that's what you are usin
I use Mosley's. I'm not in the Top Ten (yet) but have only been contesting since 1994. My PRO-57A works FB, and I plan to stack another one I picked up recently. I don't have any experience with othe
W4AN suggested: Thanks for the tip Bill. I'll give it a try. I think the biggest factor limiting such comparisons is the terrain. I'm on a decent ridge that may have a pronounced enough effect to mak
I'm convinced that the *terrain* differences are far more significant than the 30' height difference. As a result, any antenna comparison is probably very questionable. So, never mind... :-| On the
If all you need is a rotatable dipole (and not a beam) you might consider matching the *boom* of you tribander for 30 or 40 meters. I've been using this idea (from N4KG) for years now, and it works v
I'm using Phillystran to hold up 100 feet of Rohn 25 here at K4RO. For the first 7 years I used unbroken 1/4" EHS. Then in late 1997, I changed all of the guy wires (twelve of them, with a star brack
I've used a stack of PRO-57*A* antennas for about ten years now. As my operating skills have developed enough, I've been able to do fairly well in contests from my home station. The antennas are at 6
With some exceptions, I think everyone who owns these beasts would like to see the company stay in business. That desire is probably in proportion to the number of units owned. I only own one TIC rin
I just converted a 40 meter aluminum vertical (33') to an 80 meter vertical. I attached about 33 feet of #12 wire to the top of the aluminum whip, and then hoisted the wire over the top of a nearby 6
I have the star bracket on my 99' stick of Rohn 25, and I can recommend it highly. I guy at 30, 60 and 90 feet, with the star bracket at 90 feet. The bracket makes for a very stable installation. It
And the other thing you've heard over and over from me is that your mileage may vary. I continue to place well in full-time head-to-head contest competitions against much larger stations with my "neg
I can testify to this statement. I used to have to climb every month or two to fix problems or tweak something. I had one piece of gear that required constant attention. I climbed at least ten times
I had some issues mounting my Mosley PRO-57A in the TIC cradle. While the boom has no truss, the bolts holding the boom splice together naturally protruded though the bottom of the boom. Essentially,
I would also like to suggest a book called "Signor Marconi's Magic Box" by Gavin Weightman, published by De Capo press. It is a fascinating read of the very early days of wireless. Mine is an advance
With no disrespect to Steve, I'll bet that I've operated a lot more contests with a PRO-57A than he has. I think that he and Ward tested the PRO-57B, but I could be wrong. There were also some questi
Your Phillystran should have EHS leaders at the bottom to protect against vandalism or unfortunate mistakes. Just use the Loos guage on the EHS segment. I've been doing that here on my Philly guy cab
When I put up my first tower, I used 4000 lb Phillystran for the top guys only. I did the same thing when I moved the tower here in 1991. I only had one antenna and it worked great. I was a DXer at t
