External Antenna
If adequate signal strength cannot be achieved with the internal antenna, an external antenna can be
used. An Antenna Kit with an antenna cable, adapter cable, clamp, and bracket will be required.
Instructions for mounting the antenna are provided with the kit.
The following Antenna Kits are compatible:
• CELL-ANTHB
• PROLTE-ANT
• CELLANT3DBPK
The Antenna Kit includes a short antenna adapter cable with an MHF connector on one end and an
SMA connector on the other end.
To connect an external antenna to the communicator, do the following.
NOTE: Antenna can be installed with the communicator powered up.
1. Remove the antenna port knockout on the top of the communicator case.
2. From inside the case, install the short adapter cable's SMA connector in the antenna port
knockout and secure with the nut provided. See diagram detail A.
3. Route the adapter cable as shown, then snap the adapter cable's MHF connector onto the
communicator's main board external antenna connector. See diagram below.
4. Install the external antenna according to its instructions, using the brackets and hardware
provided with the External Antenna kit.
5. Connect the Antenna Kit's antenna cable to the adapter cable's SMA connector previously
mounted to the communicator case back.
6. Set the INT/EXT Antenna Select Switch to the EXT (External) position. See diagram Detail B.
7. When complete, perform a communication test (press and release the Test switch).
