Type 14
Type 14 was operating in S band air surveillance radar used in the British Chain Home Extra Low (CHEL).
The radar was a direct development of the Type 13 height finder, which often had problems with the nodding mechanism and was then used with a fixed tilt as a simple search radar. Then, to improve the bearing resolution, the antenna was mounted rotated 90°. For better coverage for elevation angles, a second antenna was later mounted above the first antenna with the tilt slightly raised. The transmit power was split between the two antennas. This design was then named “AMES Type 14 Mark Ⅲ”. The transmitter and receiver are identical to the Type 277 naval radar.
