I believe Array Solutions and F12 web sites both show galvanized masts. I bought one from US Towers but not sure if they routinely sell them. 73, Dan, N5AR
It is not a secret Phil. I have been using those trailer connectors for some time. They can be installed on a rotator, using pigtail leads, on the tower without soldering. Just use crimp connectors a
Dick Weber, K5IU, did analysis of this problem in Determination of Yagi Wind Loads Using the "Cross Flow Principle" in Comm. Quarterly, Spring 1993 issue. I believe this is the most comprehensive wor
Danny, are you familiar with L.B.Cebiks modeling work with quads? You will find a great deal of information on all types of antennas on his web site at www.cebik.com. click Tales and Technicals. Info
Mike: I have an old power hack saw which does an excellent job on 1/4 al plate. It is the type which is on a floor stand and operates either vertical or horizontal. I use a fine tooth blade, 24 or 32
The BAMA web site shows AR22A manual. When I try to download it I get an error message. Other CDE rotator info there seems to work OK. He might try that. http://bama.sbc.edu/cde.htm 73, Dan, N5AR
Hi Greg: You are correct, they are mounted to a plate with a hole in it large enough to let the output shaft pass thru it. The unit shown in the ebay add is missing a large bevel gear which mounts to
I agree 100% with Steve. My TX472 was a bit snug when I first put it up and had a tendency to stick when lowering if there was any side wind force. It did not have power pull down. I had to free it u
Dink: Neither you nor any of the respondents have mentioned the easiest and most informative test you could make, in my opinion. Does the antenna show deep nulls off the ends of the elements and a re
Another possibility is a standard bearing with a bushing. When I decided to replace the bearings in the pulleys on my TX472, 3 different bearing houses could not find a replacement, even after contac
Hi Bruce: I own 2 OR2800P/A and one G1000SDX rotators. I like the circular readout on the Yaesu and after some early trouble with the control box it has been reliable. The M2 jobs have been flawless
Have you checked with the Yaesu parts people? Their new number after a recent move is 714 827 7600. I have had good service from them when ordering repair parts for my FT 1000D. It is difficult to we
Mark: There are many 4 square antennas in use. I believe most are for 80m but they are also used on other bands. W7EL was a pioneer in analyzing the array as well as similar driven arrays. I have a d
Ken I have used 4 Hytowers in a 80m 4 sq array for about 10 years. The stubs for all bands were removed . I used the towers in their 52 ft form, feeding the center wire at first. Bandwidth was quite
I believe that one of the most important factors involved in small signal switching has not been addressed. That is the mechanical nature of the relay contact assembly. Some relays are designed so th
I recently acquired a CD 44 rotator and control box which was not working. After checking it out, I determined that the motor capacitor(120-140 mfd @ 50 VAC) was shot. I had a couple of small Nippon
The manual file at www://bama.sbc.edu/ shows a CD44 manual. Could that possibly help you? They have hundreds of manuals in their files. Manuals are freely available to the public and have helped me s
The proper URL is http://bama.sbc.edu/ , at least thats what appears in my computer window when I go there. Hope this workes better. 73, Dan, N5AR ____________________________________________________
