Before connecting the antenna
Do not use any other antenna than the TT-3053A antenna with the EXPLORER 527.
The antenna connector is located in the rear connector panel.
Use one of the antenna cables delivered with your EXPLORER 527. The antenna cables are 50
Ω
cables with male TNC connectors, an angled connector at one end and a straight connector at the
other end. This line carries RF, signaling and DC power for the antenna.
Connecting the antenna
Connect the antenna as follows:
1.
Make sure the EXPLORER 527 is switched off.
2.
Connect the antenna cable between the antenna and the
antenna connector in the rear connector panel of the
EXPLORER 527.
Note that the TNC connectors on the cable are different,
one end is straight, the other is angled.
CAUTION!
Do not connect the antenna cable when the EXPLORER 527 is powered!
The inrush current may cause damage to the antenna connector.
Important
When installing the antenna cable, protect it against moisture by using self-
adhesive tape or similar wrapped around the coaxial connector. Also be careful
to secure the cable run from the antenna at short intervals. An unsupported
length of cable will vibrate when the vehicle is in motion and could negatively
affect the connection over time.
