2.6 Antenna
2.6.1 Overview
Paragon-III commonly uses three antennas (one transmit and two receive) unless a duplexer is used
with one of the receive antennas; then only two antennas would be needed. They should be mounted
according to any guidelines supplied with the antennas. For antennas placement and spacing, consult
System Engineering.
2.6.2  Cabling and Connection
1-  Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the
selected antenna position(s) to the Paragon-III Radio assembly.
2-  Terminate the RX-1 and RX-2 cable-ends at the Receiver modules rear position with an N-type
connector.
3-  Similarly, terminate the TX cable-end at the Power Amp’s module rear position with an N-type
connector.
Caution:
When terminating RF cables use brand-name crimping tools (such as AMP, Jensen,
Crimp-Master, etc…) of the correct size for the cable and type of connector used.
Common pliers are NOT acceptable.
2.7  Completing the physical Installation.
Paragon-III products are factory-configured to user’s requirements and are shipped ready to run.
After new installations:
  Re-check that all connections are secure on the radio-BDLC assemblies (antennas, PC, power
cords etc.)
  Check that fuses are inserted.
  Turn both BDLC-III and radio power ON.
You are now ready to check for normal operation (as per paragraph 2.8) and to run the Dataradio
CDip program for testing or trouble-shooting.
Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using
the CDip program.
2.8  Checking out Normal Operation
1-  Check that power is applied.
2-  Check Radio assembly lights for proper operation as per section 3.1.1
3-  Check for proper operation of the BDLC-III’s LEDs.
4-  Using the CDip program and an in-line wattmeter, check forward & reverse power to confirm
main antenna installation
5-  Using CDip, check the RF Data Link with a mobile that can be heard (as per section 4.3.1)
If user application and mobiles are available, test the installation by going through a normal sequence
of transmitting and receiving messages.
