The 80 percent guy anchor radius is just a guideline, it can be less if properly engineered. The bigger problem may be with the rotating rings. I believe that most rotating tower component manufactur
A mast 5' into the tower is very sufficient. You don't have to mount your antenna at the top of the mast! John KK9A I just purchased a new TX-455 in August 2011 and it's installed with a 4L 30/40m St
The price is hard to find and I saw one site showing that the product is discontinued. The EHAM review shows it costing $350. http://www.eham.net/reviews/detail/1427 Add the cost of the rotator and y
This is a very dangerous way to lower your tower. As the tower becomes horizontal, so does your pull rope creating a lot of force. You need a higher support for your pull rope or use a tow truck. As
That is surprising since Salisbury, NC is pretty rural. GL, KK9A / 4 I thought this might interest you all as tower owners. If anyone knows of other materials in my defense please forward them. This
Perhaps this is why the antennas are not for sale? http://www.radio-sport.net/ham_lawsuit2011.htm John KK9A Hello, Do you know about HI-Z antennas? They told me they are not selling this antennas any
The SWR should not change much if you check it at 30-40 feet high. I would think the full band setting would be the most common so I doubt that you are the first one to have a problem. Is this an OWA
You used the wrong Belden coax. 8267 is tough as nails and does not act like a garden hose. Andrew LDF4-50A is also tough, in my opinion. John KK9A That was basically the reason I went to the LMR 400
Well it is made by Telrex! They were located in NJ and have been out of business for at least a decade. They used A/C motors with a selsyn connected to the motor and another one in the control box fo
When I moved to my current residence I laid my cables across the ground. After two days nothing worked, the wires were all chewed up. Hi Steve, I'm using two runs of 14-3 to run my Yaesu rotor. Total
I use house wire for the rotator motor. Since my runs are long and the motors are large I needed a large conductor. The clear outside coating flakes off after a few years, but otherwise house wire ho
To get the main lob at 3 degrees the antenna would have to be 200' high (assuming flat ground). This is a poor choice since it leaves a big null at 7 degrees. I have had good results on 15m with a si
He never said what tower or height his tower is. Rohn has freestanding specifications for 25, 45, 55 and 65 towers and they also make SSV self supporting towers. Doesn't that contradict the basic rul
That is a good question! I have used a Rohn EF2545 gin pole for Rohn 55G however I would not recommend doing this. John KK9A / P40A To: <towertalk@contesting.com> Subject:[TowerTalk] Gin Pole for Roh
I have no experience with the Orion rotator, however I have installed a reed switch on a prop pitch motor and it was pretty easy. I left a .060" gap and it worked fine. I do not think that the spacin
