After alot of hard work and alot of fun my tower is up. In the following pics you will find a 50 foot total height Rohn 25G tower. The tower contains a AS-1405 225-400Mhz log periodic that has been tweaked to be mounted tower top. Below that antenna is a 900Mhz yagi for undisclosed purposes. Down the tower is a scantenna that will soon be taken taken down. (I hate scantennas). And futher down the tower there is a PAR SWL HF longwire. And soon to be mounted at the top of the tower will be my newest antenna that is being built by the guys at KMA antenna as we speak. It is a 12 foot boom 225-400Mhz log periodic antenna that was originally designed for Northop. All of the directional antennas are turned by a CDE Ham III rotor. The tower is set in a 4 foot square hole that contains a bit more than a yard of concrete and heavy rebar cage. The ground system that is not yet complete is a series of 4 10 foot ground rods all bonded to the service ground point of the home. A proper ground is very important. So far performance has increased. With better height and being able to turn the antennas I can see a good increase in range. And special thanks to Brent or on Radioreference you know him as "123". We worked till after dark tonight hanging antennas.
