VHF/UHF Update

Wed 01 July 2009

Well, things took a slight turn for the worst last night. After receiving the UT-10 and the coax, N-connectors, and rotator control wire I realized that the pole I have stuck up in the air isn't wide enough to support the rotator. Apparently the pole is 1" in diameter and I need at least a quarter inch more for the rotator to grab on to. Of course not knowing this I went down to Lowe's last night and purchased a 1"x10' pipe to mount all the antennas on which will no longer be of use. Not sure about what to do with the lower portion (under the rotator) but I'm pretty sure I can just return the pipe I bought and buy a larger one.

I also sat down with a pencil and paper last night and figured out how I was going to mount the three antennas on the pole. Since the 1.2GHz antenna is a loop antenna and can't tolerate anything metal in the middle of the field that antenna will be at the top of the pole. 14" lower will be the 70cm antenna and then 79" below that will be the two meter antenna. This will leave enough room for the h-plane of each antenna to be unobstructed by the other antennas for a better performance.

Now if I can only figure out how to get them up in the air.
