I am planning to put up a new HF beam, but need to get rid of the old system first. It consists of a Cushcraft A3S (stainless) 20-15-10 meter beam, a Hygain CD-45II rotator and a 32 foot Rohn HDBX freestanding tower (with the mast, it puts the antenna at about 40 feet). It is available free to anyone who will come and take it down. Here are the details... The antenna: The antenna is in excellent condition, not missing any parts and works quite well. It comes with a balun. The feedline is shot and would need to be replaced. The tower: This is Rohn's heavy duty model (18 sq ft of wind load). It consists of 4 - 8 foot sections. You could add another section or two to it (though at reduced wind load). It is free standing (no guy wires) and hinges at the base so it can tilt over. Currently it is in something called an "earth base". This is a steel cylinder about two feet in diameter and 4 feet deep. It allows the tower to be supported without concrete. The tower has been held up by this base through significant wind storms for about 15 years. If you use this base, there is no need to buy and install any concrete for the tower. However, to use this base you would have to dig the dirt out of the center of the base to remove it. I'm pretty sure I also have the original (unused) tower legs that could be used instead if you want to install the tower in concrete. The tower is rusty and should be repainted, but it is structurally sound. The rotor: Both the rotor and the control box need repair. There are shops that will remanufacture/repair these things (see, for example, www.rotorservice.com) for a very reasonable price. This package is available for free if you get together a group of people and take it down. The easiest way to do this (I've done it before) is to get about a 60 foot piece of heavy rope and attach it at about the 20 foot level of the tower. Then one group of people can stand in a bedroom of my house easing the rope down and another group can stand behind the tower and lower it. A pile of concrete blocks can hold the top of the tower off the ground so that the antenna doesn't actually hit the ground. Then the antenna can be removed and the tower disassembled. However, it has been a quite a number of years since it was last lowered and I expect the tower bolts will be quite rusty. Antenna is located FN02hk
