A-99 and it's clones are a great antenna as long as they are mounted at least 36 feet above ground.
The ground plane kit does nothing to improve transmit or receive, but DOES help dramatically reduce common mode currents which enter the shack on the coax braid and cause all kinds of problems (like squealing mics).....
Hanging four 108 inch wires from the base of the antenna achieves the same effect and is much cheaper !
I've talked all over the world on A-99's. They'll never perform like a beam or other directional antenna but for a vertical they work well.
