Abstract
A mobile antenna system for use at frequencies in and above the 800 MHz band having a collinear radiator (10) mounted on one surface of a dielectric (14) such as the window of a vehicle and a tunable coupling circuit disposed internally of a conducted housing (22) mounted on the opposite surface of the dielectric (14) which acts as a counterpoise for coupling RF energy between the radiator (10) and a transmission line (42) connected to a suitable transceiver
