Requirements

• Center frequencies for the receiver and
  transmitter antennas are required to be 2036.74
  MHz and 2211.84 MHz respectively.
• Boresight gain gt 0dBi (60 degree cone around the
  boresight). Gain gt -10dBi over rest of the sky
• Right Hand Circular Polarisation
• The antennas should have the appropriate
  grounding to prevent static build up.
