2.3.1 Recommended tools and supplies
•
Electric drill for mounting holes
•
Hammer and center punch
•
Tie-wraps
•
Drills and circle cutters as needed according the size of screws (or nuts and bolts) used.
•
In-line “Power meter” capable of measuring forward and reflected power at the operating fre-
quency of the radio.
2.3.2 Physical mounting of GeminiG3
a) Start by running all the cables (DC power, PC –
Ethernet or RS-232
- as well as all antennas ca-
bling) prior to mounting GeminiG3 unit to assure the feasibility of the planned cable routing.
b) Be sure to leave sufficient slack in each cable so the GeminiG3 radiomodem may be removed
from the mounting bracket for servicing with the power applied and the antenna attached.
c) GeminiG3 unit is ready for installation.
Cautions:
•
When drilling mounting holes, be careful to avoid damaging some vital part of the vehi-
cle such as fuel tanks, transmission housing etc. Always check how far the mounting
screws extend below the mounting surface prior to installation.
•
Use of drill
bit stops is highly recommended.
•
After drilling, remove all metal shavings before installing screws.
•
Do not overtighten self-tapping screws.
1. Once you have found a suitable mounting position for GeminiG3 unit, hold the unit and the unat-
tached mounting bracket in the proposed mounting position and check that there is clearance behind
the unit for the heatsink, cables, etc. Check that the position provides a large enough flat surface that
the bracket will not be distorted when installed.

2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again,
ensure that drilling at the selected points is safe and will not cause damage.
3. Indent the drilling positions with a center punch.
4. Drill holes sized for the self-tapping screws or for the nuts, bolts and lock washers used.
Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal.
