The 10 GHz beacon was the first of this group of beacons to go on air (10th July 2008). It runs 0.5W into a 10dBd waveguide slot antenna at 30m agl.
The 24 GHz beacon was added on the 18th September 2008 and runs 0.25W into a 10dBd slot antenna.
The site itself is 35m asl.
A 27 MHz temperature controlled crystal oscillator is phase locked to a Racal 9420 5 MHz frequency standard, then multiplied by 384 to final frequency. Keying modulation is applied to both controlled and reference oscillators. An output power of 5W is generated at the transmitter to overcome a feeder loss of 10 dB (37m of LCF12-50J).
