How hard could it be. The wires would be the same, the posts the same...I don't buy the dropout bit with rt angles. What kind of connectors was he using? I would reccomend tryingf a different one if he was having problems. How much was he charging for such a beast at cuiosity. Wish I had some rt angles, I would build you one myself just to see if it works. I have the extra coax cable sitting here!
