This version allows better positioning & separate heights from solar panel. I've now had both versions & like the single arm version than the dual arms.
I have tried other Yagi antennas with no luck. I put this on a piece of 2 inch PVC made it look like the tree and now I have the best signal I ever had at this location. This is a great product for a great price shipping is Fast.
Use this cell extender in a remote part of Texas on our hunting lease. Works great!
Work good made a big difference ..recomended to a friend and he ordered them as well...
