Hi, I had dug through the refelector archives. To recap, it seemed US Tower has recently recommended that beeswax could be used to lubricate the tower legs to help them slide better. That sounds good
Hi, I am in the middle of getting a used US Tower ready to put up. It has the MDLP1000 unit with the Dayton 1HP motor. Without the belt on the output shaft of the motor (free), I am unable to get it
Hi Gerald, Thanks, I've gotten many off list replies. Most said to try replacing the starting capacitor first. But I few had mention to check the start circuit throwout switch. I will say that I did
Towertalkians / Gerald, I replaced the starting capacitor today and that didn't fix the issue. I guess its down to pulling this motor apart now. Is the start winding circuit exposed on the fan side o
These anchor bolts are what they show in the engineering documents. You think an inspector would feel better that you used something else? -Scott, WU2X _______________________________________________
I asked this question a long time ago on usenet and here was the answer, which I followed: http://groups.google.com/group/rec.radio.amateur.antenna/browse_thread/thread/896969fe57605e51/2a3ae24972edf
I would second uship.com . I had my used tower shipped using a bidder from uship and it worked out great. It was more economical than me renting a trailer and towing it with my own truck. -Scott, WU2
Hey all - I am planning my grounding system for my new tower. I am going to run multiple ground rods. I have a bunch of really old 9913 and RG-8U. What would be the best way to use this to connect gr
Look again - 30 is the weight, not the price. -Scott, WU2X _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.
What I would recommend is mounting the quad like a "+" rather than a "X" and then you can support the coax and feedpoint properly with a spreader arm. To me this is the logical way to do it plus it h
Yes, the worst offender I have seen of this is LMR-400UF. Its a nice coax for running in the shack, but its so hard to hand prepare that I consider it worthless. I did the trick where I flowed the so
Hi - I just put a new amp into service in the shack and I bought some Amphenol 90 degree adapters because I need to have the equipment closer to wall. I read bad things about using these when cheap i
Hi All, I've been in several discussions with some local contesters/DXers over the High Frequency Terrain Assessment (HFTA) software included with the ARRL antenna book. I have used the program mysel
Hi All, Yeah so largely anecdotal / empirical evidence seems to say HFTA generally seems to coincide with the results observed in the real world. I was more curious about the technical reasons why HF
There was a good article recently in QST on this subject. This article prompted me to get off my butt and follow up on this stuff, esp. since I just completed a tower installation. As the article sta
Hi All, I was modeling a Cushcraft 402CD loaded 40m yagi. I use Nec-Win Plus and MultiNEC. I enabled stepped diameter correction in both programs and noticed that in both programs a taper correction
I just installed a HDX572 myself. Back-fill can be the equivalent of undistributed soil if its done properly and then tested. The contractor who gave me a 25,000$ quote to build a form, back fill and
Typically, you aren't going to notice the difference by reducing the SWR any further. If your radio and amps can tolerate it, then the SWR is already good enough and there is nothing to gain by tryin
Does anyone know of a source for a rigid dipole made from aluminum that can be reconfigured for use on any one particular band from 20m - 10m? It would be simple to construct from telescoping aluminu
One more thing to add is, if you want to be sure then have it crush tested. I figured this would cost a fortune, but my local concrete testing place gave me the cylinders and rod for free, and showed
