antenna Installation and Safe operating Distances
Before installing the DRH-01-100 at the operating site, the following
details regarding desk or floor space, rack clearance and lightning
protection should be considered.
antenna minimum Safe Distance:
5 ft.
antenna Gain:
Zero dBd referenced to a dipole.
antenna mounting:
The antenna supplied by the manufacturer or
radio dealer must not be mounted at a location such that during radio
transmission, any person or persons can come closer than the minimum
safe distance to the antenna.
To comply with current FCC RF Exposure limits, the antenna must be
installed at or exceeding the minimum safe distance shown above, and
in accordance with the requirements of the antenna manufacturer or
supplier.
Warning:
You, as the qualified end-user of this radio device must control
the exposure conditions of bystanders to ensure the minimum separation
distance (above) is maintained between the antenna and nearby persons
for satisfying RF Exposure compliance. The operation of this transmitter
must satisfy the requirements of Occupational /Controlled Exposure
Environment, for work-related use. Transmit only when person(s) are
at least the minimum distance from the properly installed, externally
mounted antenna.
antenna Separation Considerations
The physical separation between the receive and transmit antennas
is critical to system operation.

Vertical
Separation
The required separation distance is dependant
on the operating frequencies and RF power
output. BK Radio recommends mounting both
receive and transmit antennas on a single
mast with the appropriate vertical separation.
The receive antenna should be mounted above
the transmit antenna.
For required distance refer to the chart below.

WaRnInG: Failure to maintain minimum antenna separation may
cause equipment damage.
