I'm considering shut feeding one of my newly installed towers for 80/160. I had good luck with this when I lived in Colorado and would like to try this again in AZ.
The tower is 70' of Rohn 45 with an XM-240 (reflector grounded) on the top. In my previous installation, I used 1/2" copper tubing spaced 12" off the face of the tower with the tap around 40'. The match was a simple Omega match using just capacitance in the matching network.
My question - would someone much smarter than me be willing to model my tower and provide direction on the matching network?
