Page 3: What Is A Diversity Kit
The EPAK Diversity Kit is combining the free line of sight ranges of 2 antennas: once one antenna is blocked in sight, the other antenna seamlessly takes over the satellite connection. This requires a high performance switching device, that can split and reroute RF signals nearly immediately. -
Page 4: Using The Vsat Divkit
Using the VSAT DivKit The VSAT DivKit comes in a robust 19" rack case, ideal for combining it with the EPAK ACUs in one rack. The holes for fixing it with screws in the rack, are on the far left and the far right side when you look from the front. -

Page 9: The Attenuator-Regulators
4.4.2 The attenuator-regulators For matching the different power levels of both antennas, four pieces of 16 step rotary switches are located at the front panel of the VSAT DivKit. This is often necessary for matching the signal power of both antennas to avoid lockouts or signal loss like de- scribed above. -
