This ground plane provides a suitable grounding plane surface for just about any antenna. Since antennas have a variety of cable entry sizes we have left this ground plane without a center hole so that you can drill your own hole using a hole saw or drill bit available at any hardware store for a wide variety of custom installation applications. Ground planes improve signal reception on most cellular antennas and are suitable for use on fiberglass and other non metal roofs that will not provide a suitable sub-straight for the antenna to perform optimally. By adding this optional ground plane your antenna will perform on non metal surfaces common in the RV and boating industry. Ground planes do not require "grounding" or a wire connected to earth/ground. The purpose of the ground plane is to provide an antenna substrate that optimizes signal reflection back into the antenna receivers. For additional questions please contact us.
