Hot Stand-by Configuration

• Dual antenna solution - No additional RF losses due to RF couplersand waveguide use

- Easy installation (each ODU is directly mountedon the back of its antenna)

- Normally used for 20 and 30 cm diameter antennas- Space diversity improvement

• Single antenna solution - Smaller environmental impact - Better wind loading resistance- Normally used for 60 or 120 cm diameter antennas- Main path loses only 1 or 1.5 dB of system gain
