Hi John -- The TR44 does have a brake but it's a gravity type brake, not as effective as the wedge-type brake on the Ham M and up rotators. You can read about it on the first entry of this page on my
Paul -- Check the article on my website called: "Repairing a Tail-Twister Rotator" at: http://www.hayseed.net/~jpk5lad/Rotors/Tail-Twister.htm I showed how some teeth were chewed out of the stainless
Users of the old Dentron MT-3000A antenna tuners don't seem to have a great deal of information available to them on the Internet. The copied and copyable pages are sometimes hard to read and the sch

Hi Kathy -- I have up a 69' Rohn 45 foldover that I've had in 3 locations over a period of about 35 years. It's a good tower if you don't overload it. I've got the engineering drawings and informatio
I've never done any "plumb bobbing" but I was wondering, if the problems are from the wind blowing the bottom weight around, would it be possible to place a pan of water on the ground right under the
I think we've always included discussions and information on antenna tuners on this reflector. I recently bought an older Dentron AT-3K tuner and there was absolutely no documentation to be found on
I tried to send this one yesterday and it did not show up so I'll try it again. I recently bought an older Dentron AT-3K tuner and there was absolutely no documentation to be found on the Internet fo
I wonder if anyone has a Hustler 4BTV vertical that didn't quite make it though a bad storm or was destroyed by one of those big antenna-roosting birds. I'm trying to resurrect my old 4BTV but the 10
Hi Jim -- I think the rule of thumb is, if you have a choice of tuning configurations, the one with more capacity and less inductance is the preferred one. Seems like I also remember reading that if
Hi Eric -- In our area, when the cable from the Cable TV folks gets damaged and you call them for a fix, they come out and lay a heavy RG-6 cable strung out just on top of the ground until they can b
Hi Dick -- If you need any additional information before you open it up, you might want to take a look at my web site. I've got several articles on rebuilding rotators, both HAM-M and Tail-Twister mo
The hole was cut for a 2" mast but Rohn also sold a cast metal bushing to stick in that hole, one for 1 1/2" masts and one for 1 1/4" mast. Not too fancy. Jim - K5LAD == == Growing old is like being
Hi Bob -- I was going to refer you to my website but I see that you already ran across it. Just one other thing -- I had a ham write me recently about the ball bearings wanting to know the size so he
Hi Bill-- Here's my version of the tower-based camera. It's a lowcost alternative to this situation and works quite well. <http://www.hayseed.net/~jpk5lad/K5LAD%20Memories/ Vols%2036-40/Memories--Vol
Kip -- Although your problem doesn't sound like it completely matches my solution, it might depend on the manufacturing age of your problem ARX2B. Back in the 1970s I owned a ham store (Derrick Elect
Hi Steve -- I've written several articles on my website about rebuilding CDE rotators including one complete article on rebuilding the Tail-Twister. I also had a problem of losing some teeth off the
Although not original, here's an article I did using some ideas from several others, but it's a duplicatable project using the ideas Don mentioned below. Although this is for switching antennas remot
and to standoffs going up the tower. I've used it for years to feed two of my top guy anchors, insulated off to be fed at the top. This KW twinlead was not 75 ohm but was actually 300 ohm. When I ow
Hi Mike -- The manufacturers of the TX2 (CDE, HyGain, MFJ) always specified it to be operated vertically to maintain that the weight of the mast and antenna array would provide the proper downward th
