So I have decided to go with the top rails, the offer the most height for the least money... and are actually perfect for antenna purposes with the tapered end for the antenna attachment. I actually was digging around, and found a pipe sunk in concrete that was used to hold a pipe up for something in the past, probably a TV antenna... So that will actually be my mount, and will fit the 1 3/8 pipe pretty tight, so its a win win on that and $20 for 21' isn't to bad of a deal...
I guess the next question, is what antenna to top it all off with. I was looking at the RS 20-176 to get the most I can, but still not be a totally obtrusive antenna... Anyone used the 20-176, or have something that might work better? I am looking to stay in the 150-160MHz and 450-470MHz range for right now, and I am not doing anything in the 800 range with my base at all, as it doesn't do trunking anyway......
My other concern is that I also live about 1000' for a county repeater that is about 150' AGL, so any antenna will have a direct line of sight. What I am trying to do is bring in some of the more distant stuff, but my concern is overloading the scanner with the stuff coming off repeater close by. There are 5 of the 15 or so freq's that I monitor are coming from 1000'' away, while the others are coming from about 20+ miles off... What is the risk of doing all this work on a nice mast and antenna, only to make matters worse with saturation on the 5 frequencies I get clearly already?
