Backpack Setup
Both the whip and RPA antennae are suitable for use in a backpack.
The RPA is installed in the same manner as for the pole-mounted setup
(see Pole-Mounted Setup, page 22).

Tip – The RPA is tuned for operation with the GPS antenna cable running
through it. Operating it from a backpack may reduce its operating range.
Trimble recommends that you use the whip antenna.
To set up the Trimble R7 for use in a backpack:
1. Insert the receiver into the backpack with the ports on the top
panel facing upwards and the front panel facing outwards.
Secure the receiver around the middle with the velcro strap.
2. Attach the Zephyr™ antenna to a range pole.
3. Attach the whip antenna mount to one of the fittings on the top
of the backpack.
4. The backpack has a feedthrough on both sides at the top and on
both sides near the bottom to allow cables to be positioned out
of the way of the main zipper. Run the radio communications
cable through at the top, and connect it to the blue TNC port on
the receiver.
5. Connect the straight end of the yellow GPS cable to the yellow
TNC port on the receiver.
6. Run the right-angle connector on the yellow GPS cable through
the top or side slot on the backpack, and connect it to the
Zephyr antenna.
7. Connect one end of the 6 ft 0-shell to 0-shell cable to Port 1 on
the receiver.
8. Run the 0-shell cable through the side slot of the backpack and
connect it to the TSC1/TSCe controller.
