ABSTRACT:
A compact police radar warning receiver is provided having an antenna in which all of the mixer and oscillator components are mounted to one side of the antenna enabling the exterior wall of the side opposite thereto to be constructed substantially flat and thereby function as one of the exterior walls of the housing. The antenna is further provided with an improved microwave oscillator, an impedance transformer and non-adjustably positioned tuning pins.
