Zack,
I use my TH-D7A with a home brew Dual band yagi (Kent Brittan's Plans). I note that once I dial in the proper polarization on the antenna I can work most of the pass with only slight adjustments. As the pass nears it's end (these are South to North passes) I notice I have to readjust the polarization of the antenna quite radically.
One thing with the arrow is that the two bands are at 90 degrees to each other, I've always wondered how that affects things. If you're dialed in on 70cm, you're going to be off on 2m and vice versa. My homebrew antenna has both bands on the same plane.

Since we are on the subject of satellite equipment, I have a question:
I was on AO51 a bit ago, and I was able to get in okay at the beginning using the THD7A for transmit, but as the pass went on it was impossible for me to get in, even when there was dead silence. I tried the D7 afterward (using the Arrow like I would for a pass) on a couple local repeaters, and I was having a hard time getting into them, when usually I could hit them with a duck. I pulled the Arrow off and stuck the duck on, and I can get into all the repeaters fine. Keeping all of that in mind, I went back to the Arrow and put a THG71A on in place of the D7 (same battery that was in the D7), and I could hit the repeater okay. I put the D7 faceplate back on, and it would not work.
With the above information, I am getting indications of both an issue with the radio and/or Arrow.
Any ideas as to what the issue might be????
