When I recently asked about a sluggish HAM-III rotor, several folks suggested that the phase-shift cap might need replacement. I have no schematic, so can't ID the cap in the control box. One fellow

A buncha guys asked: The cap I got is not an exact "form/fit" replacement, so you may want to do more shopping, but.... .....Grainger number is "4X059". It's 130-156mfd, 110-125VAC, non-polarized ele

I agree, a clever idea! I've used laser pointers in meeting rooms at least 80 feet long, under reducted lighting. If nothing else, do it at twi-light. Presumably we're just talking about fine-tuning
Got my MT-61B (old Wilson equivalent of US Tower MA550) raised today. What an improvement over the old aluminum 40-footer! But my HAM-III seems to wimpy to twist it properly. It turns, but **very** s
I've just acquired a used "Wilson Systems" MT-61B tubular telescoping tower. I suspect (but don't know for sure) that this is now the US Tower model MA-550. Before putting this heavy thing in the air
Has any of the assembled gurus figured out a way to suspend the center of a dipole from rotating towers such as the US Tower MA-550? 73, de Hans, K0HB -- FAQ on WWW: http://www.contesting.com/towerta
Thanks for so many responses The best answer, as usual, turns out to be elegantly simple. Put a thrust-bearing ('upsidedown') on the mast, attach a peice of angle stock (or fiberglass) horizontally o
Actually it's 4 J-bolts, but who's counting! My tentative plan is a bit more devious. The current tower sits on 6 (three sets of two) channel-iron stubs (from old telephone central office equipment r
The existing tower is a Universal aluminum, sitting on 3 yards (4x4x5) of concrete. The new tower is a Wilson MT-61B (earlier version of US Tower MA-550 tubular) on a MARB base. This base is a 4-hol
Need a thrust bearing to fit on 2-inch mast. Light duty application, so need not be too husky. 73, Hans, K0HB -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contest
I don't know anything about the GS065 or the TB3. I just got a new Yaesu GS050 in the mail today, ordered for a real light duty application. It is a piece of junk, light pot metal, sloppy tolerances,
I have a Wilson MT-61B (55-foot 3-sections) laying down right now. It will be hard enough to replace cables in the horizontal attitude. I can't imagine any non-heroic way that you could do it when th
Visit your local auto glass place which does windshield sealing. Forget what they call that stuff, but it's similar to "coaxseal", $10 buys a 100-year supply, and it stays flexible forever-and-ever-a
Wrong. Just plain wrong. While the block and tackle gives you a mechanical advantage, the gin pole is carrying *only* the weight of the antenna (200 pounds), either with a single pulley at the top, o
