Building my new ground station and another question. I have always only elevated my antenna 90 degrees. I loose about 20 25 seconds while the azimuth rotator turns 180 degrees to track the rest of the pass. I have just let the coax hang off the back of the antennas in a big loop. I am afraid it will get hung up going 180 degrees. Question, Can I attach the coax to the antenna boom and run it back until it gets to the cross boom or will that throw off the radiation pattern? Thanks 73 Mike K4MIA
Yes, you can, just pay attention to how far your coax turn is from your driven element. There are a couple spots to avoid.
It is pretty well explained in Kent Britain's (wa5vjb) paper here: http://www.kk0sd.net/metalboom/metalboom.htm
