Claim 13

The antenna of claim 2 wherein said radiating element is a dipole.

Claim 14

A field adjustable sectoral antenna comprising: a flat reflecting surface having a front surface and first and second sides; at least one radiating element mounted in front of said front surface; and a pair of side panels each having front and rear edges and inner and outer surfaces; and mounting means for mounting said panels with said inner surfaces along respective ones of said first and second sides of said reflecting surface for field selective forward and rearward sliding movement of said side panels relative to said reflecting surface; and wherein said mounting means comprises slide members comprising at least partially threaded studs on said reflecting surface; and guide members comprising slots in said side panels for sliding over said slide members for fixing the relative position of said guide members relative to said slide members; said mounting means further comprising nuts for tightening on said studs over said slots and against said side panels.

Claim 15

A field adjustable sectoral antenna comprising: a flat reflecting surface having a front surface and first and second sides; at least one radiating element mounted in front of said front surface; and a pair of side panels each having front and rear edges and inner and outer surfaces; and mounting means for mounting said panels with said inner surfaces along respective ones of said first and second sides of said reflecting surface for field selective forward and rearward sliding movement of said side panels relative to said reflecting surface; and wherein said mounting means comprises slide members comprising at least partially threaded studs on said reflecting surface; and guide members comprising slots in said side panels for sliding over said slide members for fixing the relative position of said guide members relative to said slide members; said mounting means further comprising nuts for tightening on said studs over said slots and against said side panels.

Claim 16

A field adjustable sectoral antenna comprising: a flat reflecting surface having a front surface and first and second sides; at least one radiating element mounted in front of said front surface; and a pair of side panels each having front and rear edges and inner and outer surfaces; and mounting means for mounting said panels with said inner surfaces along respective ones of said first and second sides of said reflecting surface for field selective forward and rearward sliding movement of said side panels relative to said reflecting surface; and wherein said mounting means comprises slide members on said reflecting surface and guide members on said side panels, said guide members for sliding over said slide members for fixing the relative position of said panels to said reflecting surface; and slide members further comprising means for fixing preselected positions for said guide members along said slide members.

Claim 17
