Review on Workman SS750DH Radio Super Antenna by David Reyes

No assembly instructions. Had to do a google image search for the build. The largest key I had was 23mm and it was too small. You will need a larger wrench or an adjustable wrench for installation. You have to drill a 3/4 hole to install it (3/4 is a bit oversized so I'm guessing everything is actually metric). Not 1/2 inch in the description. Pass the bottom through the bracket. Then a black puck. Then a serrated washer to secure the plastic bushing to the top bracket. If you tighten the top bracket while holding the bottom bracket, the inside of the bracket will start to rotate. "Cosy" is all you get. Radio Right Channel sells the same product, so I think it should be pretty decent.
