1. A communications antenna system usable to radiate radio frequency energy generated by a transceiver at frequencies in excess of 800 MHz and attachable to a dielectric member of a selected thickness, the dielectric member including at least spaced apart, adjacent first and second conducting members having a predetermined spacing therebetween, the antenna system comprising:

  • an elongated radiating member attached at one end to a supporting member, said supporting member having a planar metal coupling member with a first dimension less than the predetermined spacing between the adjacent conducting members with said coupling member positionable between the first and second conducting members, including means for affixing said supporting member to the dielectric member;

    a coupling system affixable to the dielectric member, juxtaposed with said supporting member, said coupling system including,means for coupling radio frequency energy in excess of 800 MHz through the dielectric member to said radiating member, said means including first and second spaced-apart means for decoupling the antenna system from the first and second conducting members and a second planar metal coupling member carried between said decoupling means with said second coupling member positionable adjacent said planar metal coupling member between the first and second conducting members and spaced from those conducting memberswith said first decoupling means overlying the first conducting member spaced therefrom and with said second decoupling means overlying the second conducting member spaced therefrom andconductive means, coupled to said decoupling means, defining a counterpoise for the antenna system with said counterpoise including a shaped metal housing defining an interior volume with said coupling means contained at least in part therein.
