Jerry -- Weight does not matter on most guyed towers. Assuming we are talking Rohn 25, you could have 5-6 more sets of guys. Each one would exert about 1000 lbs of downward force on the tower. With 5
The biggest difference is that it is unfused. Also, the connections where the drop meets the downlead might not be as well insulated as the insulation on a modern drop. The fear comes from the power
A small quibble with your analysis, Dave. It is impossible for the horizontal tensions at a common guy point to be unequal, if the tower is plumb. If they were, the guy point would move to a position
Tim -- Nice site! If you like, you might want to add the logging program I have been working on to your budget contesting lists. It's free, so the only non-budget consideration is that it won't run o
Here is what I use: 1 - 7-8' 2x3 or 2x4 1 - 2' 2x3 or 2x4 (actually just make it 6" wider than the width of your tower. Sandwich the two 2x3s with a piece of 1" (actually 3/4") stock in between. Then
I just purchased a tension gauge for 3/16" - 9/32" cable, direct from Loos. I ordered it on Monday, received on Thursday (today). Price was $37.49 + $3.88 shipping (UPS ground). It's a very simple de
In a properly guyed Rohn 25/45 tower, I would expect both bolts and compression to provide *none* of the strength. I would expect that all the legs should be in compression all the time. The bottom e
Dave -- You own a dangerous tower. Sorry to point this out, Dave, but your tower is not very strong. Go to http://www.ustower.com/selfsupport.html and look at the weights and section sizes for a US T
I put up an X9 in May using a crane. Please note that that this changes how you should handle the "boom shelf" installation. For those who are not familiar with the new Cushcraft boom-to-mast clamp,
A while ago I requested a schematic for the Dentron SuperTuner 160-10 AT transmatch. William Lee, N5WRX was kind enough to scan in the schematic from his manual. His schematic was yellowed with age,
http://www.loosco.com/naples/tension.htm is the web address of the manufacturer of the tension gauge. At one time (maybe still) they would sell direct. Tom - N1MM used but hi). not of "make the Does
I attached a 10" wide copper strap - really roof flashing - to my tower. I had alread mounted a piece aluminum angle stock to the bottom of the tower to hold a weatherproof enclosure. I clamped the f
I thought the reflector might like a report on the raising of my X9 on May 15, 1999. The 100' crane arrived at about 7:30 AM. I was surprised at the small size of it. It is capable of hoisting severa
Did anyone see the presentation at Dayton on the X9 vs C31XR? Could you summarize for the reflector? Thanks! Tom Wagner, N1MM -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: t

I just bought a Cushcraft X9, and have been thinking about how to raise it. Tramming is out, I just don't have enough room. I had resigned myself to building it on the tower -- a prospect that took a
Dan & Bill -- Thanks for your responses. Bill -- I had a feeling KC1XX didn't use a $15 come-along. I don't have a juma, but I can buy 3 guy grips to accomplish the same thing. Hank -- I keep forgett
That does sound safer, albeit slower. If I can't get a crane, that's how I'll do it. Thanks. -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administr
Some observations on this subject... 1) Some participants come to the discussion wanting to support a specific set of antennas and some come to the discussion wanting to erect a mast "for all time".
I am rebuilding my TH-7 and wanted to replace the rusting trap screws with SS versions. Well that went fine, until the trap wire (aluminum) broke, from what I guess was "work hardening". So my questi
