Integrating ProFlex 800 into Your Application
• Conversely, there is no antenna delivered as standard with
each of the available radio receiver kits.
• However two UHF accessory kits are available, including a
UHF whip antenna and coaxial cable, for use with the
built-in radio receiver of your ProFlex 800. These two kits
are more especially intended for marine surveying. One
includes a 30-meter coaxial cable and the other a 10-
meter coaxial cable. If these kits are not suitable for your
application, the choice and purchase of the appropriate
antenna and cable will be your responsibility.
Cellular Antenna Connect the cellular antenna directly to the SMA connector
on the receiver front panel. The best performance of the
antenna is obtained when in vertical position, meaning the
receiver should as far as possible be in vertical position as
well, with the front panel oriented upward or downward.
As mentioned earlier, with the receiver installed on board a
vehicle, you may need, for best coverage, to use an external
cellular antenna. In this case, you will have to use a coaxial
cable (not provided) to connect this antenna to the receiver.
Remember the type and length of coaxial cable used may
significantly impact the performance level of the cellular link.
Bluetooth Antenna Connect this antenna directly to the reverse SMA connector
on the receiver front panel. The best performance of the
antenna is obtained when in vertical position, meaning the
receiver should as far as possible be in vertical position as
well, with the front panel oriented upward or downward.
Cables and
Connectors
After installing the receiver, connect the different cables
needed for your application.
Take the usual precautions to properly anchor the cables to
the vehicle, machine or ship structure, in order to avoid any
risks of malfunctioning due to unreliable connections.
Make sure the sealing caps of all free connectors are properly
inserted into these connectors. This will ensure an efficient
protection not only for these connectors but for the receiver
as well.
Earth Terminal In some applications, and more particularly in marine
applications, you will need to electrically connect the receiver
chassis to the superstructure.
Use a large section of braided wire to connect the receiver’s
Earth terminal to the superstructure. The shorter the
connection, the better. On the receiver side, use a screw
