Antenna Choices
The following classes of antennas (Table 1) were tested and approved for use with
the RM912HP.
Approved antennas
Antenna style Gain
High gain helical loaded omnidirectional monopole <= 5 dBi
High gain omnidirectional dipole <= 8 dBi
High gain Yagi directional <= 6 dBi)
Table 1
Antennas of like design with less gain than the type tested may also be used. The device
is always professionally installed and uses unique connectors.
