Installing a High-Speed Solid-State Antenna Switch
The high-speed solid-state antenna switch is required for a single antenna, single frequency operation.
With the use of the antenna switch, the SLR 1000 Repeater can be configured as a Direct Mode
Range Extender for use with the Extended Range Direct Mode feature. Alternatively, two separate
antennas may be used for RX and TX operation, but a minimum of 40 dB isolation between the two
antennas must be maintained.
CAUTION: The high-speed solid-state antenna switch is only operable in Extended Range
Direct Mode (ERDM) mode and should not be installed in the repeater if all the channels are not
enabled as Extended Range Direct Mode. Operating in any mode other than ERDM, may cause
damage to the antenna switch board.
Prerequisites: Obtain the following:
Contents of the antenna switch package. Consists of:
- One antenna switch
- Two M3 screws
- Two Micro Coaxial (MCX) cables
- One power cable
T10 bit screwdriver
T20 bit screwdriver

a Turn the repeater over and remove the four M4 screws using a T20 bit.
b Hold the cover onto the chassis and carefully turn the repeater over.
c Slowly remove the top cover, making sure not to damage the front panel flex cable.
3 Disconnect the following cables. See Figure 30: SLR 1000 Repeater Front View (without top
