I've heard people in the past using 102 whips as base station antennas, and they did it by having a ground plane made up of horizontal wires on 4 sides under the antenna.


1. If I go this route can I use copper wire as the ground plane? Or does it have to be steel of some sorts?


2. Since the 102 is nearly 9 ft tall, do the horizontally wires under each side of the antenna need to also be the same length of the antenna? Or could I just make a cross out of two pieces of 9 ft wire so as each length of wire on any side under the antenna was roughly 4.5 feet?


Thanks in advance.
