I got this supply from a ham that had a large antenna farm and decided to dismantle everything and sell all. I have 36 guys of 6700lb and 21 guys of 4000lb, various lengths up to about 300 feet. I am
I was pulling out some old sheared off T-posts with the tractor yesterday when I found a piece of electric fence wire that had been buried since 1977. It was still good and not even rusted. 73, Keith
Dick, I am looking at page 55G-9, drawing C870496 R2, Guying details for 100'-200' 55G towers, 90MPH basic wind speed. There is a table on this page that has all of the info you are looking for. For
one. That's a pretty broad statement to make. If so, how come all the big guns use very big antennas? 73, Keith NM5G The BW price seems a little high, considering they are advertising in a ham magaz

I would leave the 45G bracket in place. Congratulate yourself that you got it to fit. The bowed brace will only slightly affect resistance to twisting. Since that is the guy point it is not important
No. It is virtually useless to align an antenna on a tower, unless you like climbing at night. 73, Keith NM5G Did everyone in the northern hemisphere forget about the North Star??? 73, Carl VE9OV ___
Thanks. I think I will stay with my current method of employing a deviation-compensated magnetic compass while up on the tower. 73, Keith NM5G --Original Message-- From: towertalk-bounces@contesting.
Actually I cheated when I installed the tower base section with one face pointing north-south. <grin> 73, Keith NM5G --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-boun
Te each his own. I have never put up a guyed tower using a base plate and do not have any future plans for one. I always use the concreted short tower section as recommended in the Rohn catalog. I ha
On Force 12 antennas you use NoAlOx plus aluminum rivets. This seems to work quite well. The only negative, and it is minor, is that you must drill out the rivets to disassemble the element. I just t
maintenance climb up the tower. We all do that, right? Well, the obvious answer for most is very rarely. I may be the exception since I regularly climb. My experience is that if a tower is assembled
I would bet he is not that far off. It is fairly easy to get a tower plumb using a simple level. I went an extra step and also used a plumb bob to set the first 50 feet. After that you can sight from
Clamp one side of the thimble in a bench vise. Clamp the other side with a large Crescent wrench. Bend the thimble sideways just enough to get the turnbuckle on. Bend back straight. Remove from vise.
What changes the resonance at the shack? 73, Keith NM5G --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] On Behalf Of Don Havlicek Sent: Thursday,
Is it resonance that changes? I thought it was impedance. 73, Keith NM5G When measuring the 'resonance' of an antenna at the shack, you are NOT measuring the antenna's resonance .. you are measuring

Interesting info. Thanks for posting. I was thinking about putting up a Tennadyne T12 for WARC and 30. But now am thinking SteppIR 3 el. What do you use on 30? 73, Keith NM5G Having had a Cushcraft A
Has anyone looked at tuning the 3-el SteppIR so it would change from monopole to 2 to 3 elements? That way one could switch from omni-directional to a tight beam as the need arises. 73, Keith NM5G --
Now made by Radian. Several vendors still carry the Rohn brand but the product is somewhat limited in availability. I am putting up three 55G towers over the next 12 months. Texas Towers is my suppli
