The older you are, the less you'll do it! If you're in your 40's (or younger): No problem, you do it just for fun and exercise! You like to go looking for problems and challenges. You are disappointe
I have a bunch of antenna and tower hardware, much of it New Old Stock (N.O.S.) stored out-of-the-weather. A lot of stuff from Rohn, Phelps Dodge, Andrew, Decibel Products, etc. Galvanized and stainl
I don't have a US Tower, but my Tri-Ex LM470 occasionally will do that. In my case, it has always been a windy day, and while the tower doesn't lean with wind, the sections do move slightly downwind.
Can't speak to your tower's size for the mounting plate. However you will probably need to drill a new bolt hole pattern in the mounting plate for the Yaesu rotor. In my case (a TriEx Tower) I had a
Does your tower have a thrust bearing? If yes is it cold where you are? Could be old/dirty/cold grease in the bearing. I chased down a rotor "low voltage" rotor problem once and it turned out my bear
Is there someone on the list who would be willing to do an antenna model for me? I no longer have NEC, and when I did, never became proficient at using it. This would be a relatively simple model, an
I don't have the same tower, but similar. And had a similar situation once. My tower uses Square-D industrial limit switches. While these are well-made all-weather devices, their internal gaskets may
I have used Thompson's Water Seal on concrete slabs. It is good stuff, not too pricey, easy to apply (use a garden sprayer), and lasts 2-3 + years before another coat is required even with heavy traf
Amen. It appears this has become a "I love my antenna" pile-on, so here's my .02. Since the original question was for multiple beams on a very tall crank up (89'), You can get almost all bands on one
I have an LM470 which has the "standard" rotor plate, suitable for HAM-M, etc., rotors, but not for Yaesu rotors and I'm sure others. I centered the rotor, drilled the extra holes, and all has been w
Yes, Rescue Tape is the best I have found. Great stuff for sealing connectors, as well as a million other field repairs. It has almost no adhesive qualities and pretty much only sticks to itself, so
ORRRRRR... Apply +/- 12-18VDC on pins 4 & 5 of the control cable (disconnect the controller). If the tower-mounted rotor is still operational, it'll turn CW/CCW depending on the polarity of the volta
I could be wrong, but I do not think that is a TriEx...I have a 1970's vintage TriEx LM470 and the tower you show in your pictures is quite different. Granted, it could be a lot older than my 70's vi
I have a T10 and a T28 on my 72' tower. Because of mast limitations, they are separated by only about 7'. They both work reasonably well altho I think there is some interaction, especially around 6M.
A friend out east who is not on this list is putting up a large self-supporting motorized/tilt tower. 1) Some months ago I sent him a link showing how one of the Tower Talk people had beefed up the t
Great info, Jim, I will forward that to my buddy who lives on the big rock (not Alcatraz)! 73 Dan K0DAN You might also see the term "chemical anchor". Simpson Strongtie is one brand. I think Hilti se
Thank you Steve, I will pass the info along. Is there specific brand or supplier you recommend? Does the number (e.g. 954) indicate any kind of strength specification? The tower mfgr recommended a pr
Wow, great information, Grant, I will forward to the guy building the tower (who really should join this forum!). The info that has come from this group has been really outstanding. Thanks to you and
Thanks Rick....very n ice design and good write-up too! I am forwarding to my buddy in NE, also tempted to do one of these on my own tower as well! Thanks a lot for sharing your info! 73 Dan K0DAN --
If you have the controller properly calibrated, and the default direction for the antennas is North (0 deg), then the rotor will go clockwise from 0, past South (180), and continue to West (270). goi
