I think you'll want to string that antenna a little higher - You can pretty much assume the higher the better. As for the Rider schematic, I guess maybe your radio schematic is included in one of the volumes I don't have.One of these times, I'm going to check out those Parabee's - There's a guy name Greg that lives nearby and who has a pair. We'll have to get him over at one of our local audio club meetings and compare his with the stock Paramours and the Zen.
