To reduce the risk of damage to the equipment, pull by the plug body rather than the output cord
when disconnecting the equipment.
Do not operate the supply if it has received a sharp blow, been dropped, or otherwise damaged. Do
not disassemble the supply.
Warning: Before connecting the external power source and the modem, make sure that the power source matches the
modem’s voltage and current requirements.
2.2. Antenna Installation
Warning: To avoid the equipment serious damage, do not switch the modem to transmit mode if RF antenna is not
connected!
Select the type of antenna that best fits your application and the one that offers the highest dB gain. In
addition, setup your system in the highest possible location to minimize obstacles between the
transmitting and receiving systems. Always place the antenna on the highest point available. At a
minimum, set the antenna to at least ten feet above the terrain using an antenna mast.
Some antennas intended to be attached to the pole mount adaptor (p/n 14-578117-01) are designed to be
operated with a ground plane and some without it. Antennas designed to be operated with ground plane
provide better gain, but to achieve the best performance of your antenna, add a VHF Antenna Ground
Plane Disk (p/n 10-587400-01) to the bottom of the antenna for a ground plane. VHF antenna Ground
Plane disk improves VSWR and as result increase RF power delivered from transmitter to antenna and
system distance range.
To install antenna with ground plane disc (see pictures below):
1. Unscrew the cone-shaped cable part;
2. Place the ground plane disc between cable parts and screw all parts together;
3. Attach cable with ground plane to the VHF antenna;
