Hi, I found what I believe to be a Rohn brand, freestanding tower. The tower looks like its good shape, so I was wondering if any one could identify this tower. Any ideas on the specs? http://picasaw
Larry, I just took the pictures today and I was going to attempt to contact Radian this coming week. In the meantime, I was trying to get some ideas on what it would handle. -Scott, WU2X ____________
http://www.radiancorp.com/ROHNNET/rohnnet2001/catalog/pdfs/selfsupport/SSV-13.pdf I think you are right. I am scratching my head over the 3.3sq/ft rating @ 80MPH. Can a number like this be compared r
It is not necessarily true that a tuner will be required, except for on the 15 meter band. I am personally running the Buckmaster OCF dipole, which they claim uses a 6:1 balun of a non-descript type.
I had the same experience. I was trying to get some more detailed info on the 20 meter yagi and I had to try and try again. Never did get it. I completely passed on them because of it. -Scott, WU2X _
Hi, Since I am in the process of designing a new directional antenna (w/NEC2), I have started to think about which measure(s) of rearward rejection I would maximize on: 1. Front-to-back - Difference
*Exactly*. This is why optimizing for gain, to me, isn't so important. Just as you said, at worst its -1dB down from something that is optimized for gain (for a given boomlength). However, the "rearw
I recently acquired a used HDX-572MDPL. I'd like to chat with anyone that has one and has been using it for awhile. If you have this model or another model in the HDX line, please drop me an email if
Hi All, I recently picked up a used Orion OR2300 rotor that I want to put into service. This is an older rotor from 1992, made by Orion Business International, Inc. I have some questions: 1. I have t
Hi, Being a new ham, I have never used a grid dip meter or actually seen someone use one. I've read the historical movement from people using grid dip meters to "SWR analyzers". I've also read that u
Dave - Thank you for addressing my question. You point out something here - this was my 75 meter loop - which is not parasitic. Its driven, so its broken at the feedpoint with an center insulator. Wo

Hi, I am in the process of trying to find a excavator to dig the footing for my HDX572 tower. To the 5 people I've talked to so far, this 5x5x8 hole is difficult. I think mostly because none of them
Yeah, I am now trying to get estimates from "concrete contractors". I wouldn't blink at something like 1800$ for the job, but I don't think that will happen here in New York. -Scott, WU2X ___________
I noticed on your installation, best I can tell, you used wire ties on the rebar. Is the tower bonded to all the rebar pieces? -Scott, WU2X _______________________________________________ ___________
Michael, The ARRL Antenna Book latest edition has a program called "High Frequency Terrain Analysis" (HTFA). You download topographical information from the *exact* location where the dipole will be,
Hi All, I am just starting to do some refurb on a used 1992 US Tower HDX572 I bought. It has the RMC-1000 remote option. I The tower is on stands right now. I took off the drive belt and without any
Yes, please play it safe. We all remember the story from a few days ago. You really need to hook a line up the tower and tilt that over properly, from the side where it doesn't fall on you. Is that s
I think I've decided on Prelube 6 for the new cables for my HDX572. How many spray cans would I need and what is the best way to apply it the first time? Should I spray the cables off the tower and t
In my case my city has verbage that ham towers are exempt from the height limits and setbacks laws. It differentiates between a cell tower and ham tower. That's good. What is not good is that buildin
