Model 316 Long Range Microwave Link

Because Model 316 operates in the K-band frequency band, it achieves performance not possible with X-band microwave links (which operate between 9.4 and 10.8 GHz). Antenna beam-width is approximately 3.5 degrees in both the horizontal and vertical planes, allowing the Model 316 to operate at long ranges and within very narrow corridors. The 316 fully complies with EC emission requirements of EN300 440.

Each Model 316 Transmitter and Receiver is packaged in weatherproof housings, which are only 269 mm (10.6 in) in diameter and weigh only 2.0 kg (4.5 lbs). Comparable X-band systems require housings which are over twice as large. This small size provides optimum resistance to wind-loading and obvious advantages for installation and shipping.

Because its K-band microwave frequency is 2.5 times higher than X-band, the multipath signal generated by an intruder is 2.5 times higher and detection of slow-moving intruders is correspondingly better. With its superb beam control and higher multipath frequency, Model 316 provides unmatched detection performance.

Narrow band receiver design increases detection probability by alarming on partial or complete beam interruption, increase or decrease in signal level or jamming by other transmitters. Its Automatic Gain Control (AGC) circuit permits the receiver to compensate for varying site conditions or changes in the weather.

Operating at K-Band, which is much less crowded than X-band, Model 316 is inherently less susceptible to outside interference from airport landing systems, aircraft or marine radar, and other microwave intrusion systems. Six field-selectable crystal controlled modulation channels with narrow band filtering allow several Model 316's to operate simultaneously without mutual interference. Model 316 can also be stacked with an X-band link, such as Southwest Microwave Model 300B, with no danger of mutual interference. Such an arrangement provides the ultimate in detection performance and extremely high resistance to electronic jamming.
