micro DOUBLE TEN SWITCH is a high performance, high power
rated, rugged, high isolation, remotely controlled antenna switch capable of selecting one of
ten (10) antennas
to one of two (2) feedlines for SO2R operation. It can be installed inside the shack or outside on the tower.
Available with UHF SO-239 connectors or N connectors.
Package includes:
micro DOUBLE TEN SWITCH, double C-bolt for tower mounting and manual on
CD. Control cable is not included. See Application
Note 29 for cable requirements.

Special double fault protection
Fig. 1 Example of one port connection
A special method of
connecting relay power is employed which prevents switching both radio ports
to the same antenna. Additional signal relays ensure maximum separation even
with a drive control fault. Without this protection,the
isolation between radio ports would decrease by half. For example, with
an output power of 1000W (60 dBm), in the event of a control fault, the other
radio port would would see 25 dBm (0.3 W) instead of -10dBm = 0.0001W.
