The YE-ZB system is different than the ZA carrisystem. The YE-ZB system was designed to give just a bearing to an aircraft to their home airfield ( most of the time, a moving aircraft ). The ZA system was designed for use more on a non-moving land based airfield, and in addition to bearing information also provided glide path information to the aircraft.

Thank you Mike and Mark for your replies.
I wasn't to far off the mark in guessing it preceeded the ZB. Wishing you both a Merry Christmas.

The ZA radio system was an instrument landing system used by the USN and USMC during WW2.
