I turn Antenna Extender

The Micro-Eye presents a bit of a problem if you want to change the antenna. Its antenna is rather closely integrated into the entire RF board design. You don't have a handy coax connector or waveguide flange to hsiok things to. Its horn does work quite nicely, and would probably make a satisfactory feed for a 1' io 3' dish.

As an experiment, 1 made an extension to the integral molded horn, fashioning it from double-sided copper-clad printed circuit board. The extension sleeves inside of the existing horn (see Photo F),

Remember; You must he very careful not to touch the mixer diode located inside of the horn!

This extension adds an estimated 8 dB of gain. Field tests verified a marked improvement in signal strength.

You could try modifications I didn't attempt, such as adding an AFC \ Automatic Frequency Control), or replacing the horn antenna with an adaptor to a Standard waveguide flange or coax connector. ;he latter modification would allow measurement of the noise figure of the receiver,

The BEL Micro-Eyc police speed radar detector is easily modified for reception of the 10 GHz ham hand, The cost is low and the performance is quite respectable. This device should serve as a useful accessory for the microwa\ e amateur.
