Recommended Antenna Separation; Step 4-Connect The Data Cables - Sierra Wireless AirLink RV55 Hardware User's Manual

Recommended Antenna Separation

The recommended antenna separation is related to the band frequency/wavelength. To
accommodate the shortest frequency/longest wavelength band supported by the RV55,
Sierra Wireless recommends a minimum antenna separation of 214 mm for best results,
and if necessary, a separation of 107 mm for acceptable results.
