One of the first things I would check is the rotator connector. The boot covering the connector does not completely waterproof this connector and the indicting system will not work properly when this
The problem with adding guy wires to a crank up tower is that it applies a downward force on the tower and the winch and cable may not be able to handle these forces. Maybe you can find another spot
It looks like there may be a thrust bearing above the rotator. There's no place to do this with a tubular tower, as shown in the photograph...and there's no way to mount a rotator inside the tower, e
TIC General used the Bourns model 3590S-1-501 potentiometer in some of their units and at one time as replacement parts. They are not water proof. John KK9A Henk, The most recent pots I got from TIC
You can lessen ther risks of your tower being hit by lightning by lowering it or moving it to an area less lightning prone. Painting or coating the system will not help. You should accept that fact t
There is a lot of information on elevated guys in the archives including this summary by WE9V: http://lists.contesting.com/archives//html/Towertalk/1998-03/msg00209.html . 73, John KK9A I've got 50 f
Normally designing an antenna is a compromise between the SWR curve and the F/B and gain is basically a function of boom length. Since the SteppIR adjusts at various frequency increments, I would gue
Try calling the Vertex parts department 714-827-7600 I think that you are looking for the following part but you should verify this number: S8101130 73, John KK9A I have a G-1000DXA rotor that I am j
I've put up a number of large antennas using this method and as Bill said it works great - even with no helpers. Since the beam isn't all that heavy and the tower isn't all that tall, why go through
I wish I knew why he copied me with this post. I have no interest in his videos. This guy again? He must think we've forgotten the last round. 73, Pete N4ZR City attempts to shut down ham radio ....
I doubt that steel price is correct. After shipping you will still need galvanizing. Depending on your antenna load you may be able to use an aluminum mast which needs no corrosion treatment and you
I though that MOVs degrade with each protection event and that their breakdown voltage decreases. Is a 45v MOV appropriate for a 33v system? John KK9A When my lightning disaster occurred, I was using
The only certain way to see the interaction is to model the system. Most of us have to live with some interaction and often it's not that bad, maybe a little less F/B or slightly higher SWR. I really
Now anyone can get experience the scary view from the former Sears Tower: http://www.chicagobreakingnews.com/2009/05/a-glass-bottom-skydeck-for-sears-tower.html I can attest to the fact that even tal
These towers do bend more than steel towers and are more scary to climb. I own a 50 Universal Tower at P40A http://www.qrz.com/p40a and I have climbed it many times in Aruba's wind. I wonder where th
I think tubing caps are unnecessary and they could trap water. I never use them. John KK9A Mine are all but gone due to age and UV. Where can I get replacements ir substitutes? Are they necessary? Ho

This appears to be another Michael Landa NL7AX website. While googling something earlier I came across usedtowers.com . It is the first time I had found it. It may be old news to some, but I found so
I am a new EZNEC user and I would like to check for interaction between two antennas that I have already modeled and created .ez files for. I do not see a way to import the wires from one antenna fil
I have a 160m vertical 3 feet from the house at P40A http://www.qrz.com/p40a and it works OK. Your vertical should work fine near the house and it may minimize any neighbor complaints so you can stay
