There is definitely different quality in cable ties. I have had very good luck with ones made by Panduit. I also have never experienced any crushing problems that other's have mentioned in this tread
I used gray PVC for the insulator on my 160m vertical and it works fine. I see no reason not to use the material that you have. You don't mention what power level you intend to transmit with, but per
Or you can calculate it and only trim your wire only once 234 / resonate frequency - 234 / desired frequency = amount to trim (or add if negative) This will also work with a dipole if you trim off th
Folding back works with both bare and insulated wire. You do not need to strip the insulation or solder anything. The antenna will think it's shorter and your radio will be happy with the lower SWR.
I wonder how many bird's lives are saved by towers. It gives them a nice place to perch high above their ground predators such as cats and also away from ground pesticides. If a bird makes a nest on
FWIW, I have had several rotator motors damaged and more rotator potentiometers than I can count on my fingers damaged by lightning strikes. I also had to replace numerious hash filters and I had sev
The concrete base is not a good insulator. You could drain any static charges by using a hairpin coil match or a large inductor. John KK9A I'm considering replacing my 1/2 square with a 1/4 wave vert
I don't know that Array Solutions still carries the 80m vertical. ZeroFive Antennas http://www.zerofive-antennas.com sells one that looks very similar to the Array Solutions freestanding vertical for
This looks like a K9AY loop with a remote adjustable termination. I have installed a K9AY loop and they do work. They are ground dependant so your results may be different than someone else's. One ni
Is there a formula and example of how much force is really on a tram line? John KK9A Let me second Dave's comment... Using rope for a tram line, or small diameter cable is asking for a crash... I als
I have never seen a set up like this, however I see no reason that it would not work well. There may be some interaction with your tribander depending on the antenna orientation, however the 10' spac
I have seen dead birds in my 3" diameter mast. I'm not sure how this happens. John KK9A Today I climbed the tower to take down the four foot lighted snowflake that serves as a Christmas decoration. J
I am a big fan of aluminum masts and I use them on both of my P40A towers shown on http://www.qrz.com/p40a . They are not as strong as steel and they do bend more so you have to make sure that you do
This is hard to answer without knowing who you wish to communicate with or more importantly what angle of radiation do you wish to cover. Once you know this, it's easy to model both antennas and see
N1UR suggested an excellent method for working on antennas. Instead of using a gin pole, I insert a pulley in the mast or at some point higher than the antenna and I can position the antenna to adjus
If you install the Yaesu G-2800DXA per the manufacture's instructions and nothing is broken, it is impossible for the mast to slip. John KK9A I do not know where he comes up with that hearsay nonsens
I used TIC rings to turn 60' boom 20m antennas and a 2el full size 40m with a 90' 80m element on my Rohn 65G. I used two motors and I never had a problem with turning them. I did have a problem with
I bought a Rohn TB-3 four years ago and when I received it and turned it by hand and it would often lock up. I returned it and got a replacement, which turned a little easier. I installed the bearing
I've seen several posts regarding the K0XG ring and they all commented on how heavy duty it looks. His web site does not show this product. I wonder if anyone on the reflector is using one and would
I have the same condition in Aruba. I just used a bunch of 2' ground rods. John KK9A / P40A After being spoiled by Florida's sugar sand in which you could dig a hole for a base for holes and anchors
