Installation

DCB, DCFCB and DCFCTB Models

Land Line Control

You may activate the controller by applying contact closures to the remote activation

inputs. Refer to the Landline and Local Pushbutton Activation section on page 28 for

a functional description and details on interfacing and wiring connections.

Antenna Installation

TO PREVENT ELECTROCUTION OR SEVERE PERSONAL INJURY; INSTALL

ANTENNA AWAY FROM POWER LINES AND INSTALL WITH PROPER

GROUNDING. Refer to section 810 of the National Electrical Code, ANSI/NAPA

No. 70. Refer to Figure 16 Antenna Grounding on page 66 for details.

A factory installed internally wired Type N bulkhead is provided on the bottom side

of the Control Unit for ease of antenna cable interface. The bulkhead requires the

installation of a male Type N connector on the antenna cable for correct interface. It

is essential that the installer follow all tuning (if applicable), installation and

safety instructions provided by the antenna manufacturer.

Yagi Antenna Installation

Yagi Antenna Pre-Assembly Instruction:

1. Unpack the antenna and locate the following parts:

 Boom (1-14” for 5 element model, 7/8” dia. for 3 element model)

 3/8 diameter elements (y---3 = 3 elements, y----5 = 5 elements)

 Gamma match parts bag

 Mounting bracket parts bag

2. Find the proper element dimension chart for your antenna, within the antenna

instructions, and trim each element according to your operating frequency. Use

care to trim equal lengths from each end of each element ensuring that the

mounting hole is at the center.

Note A: Proper trimming and adjustment is critical to the Voltage Standing Wave

Ratio, known as VSWR. (High reflected power levels decrease forward

power. The life of the radio and transmit capabilities are dependent upon

the VSWR being low as possible).

Note B: If two frequencies are being used, then trim the antenna to the transmit

frequency of the unit where the antenna is mounted.
