Antenna choice & replacement
The XRMA multipolarity antenna provides enhanced
coverage when mounted on an unobstructed area of
a vehicle’s roof and should be connected via the sup-
plied low loss coax cable to the output of the mobile
charger. Alternatively use of an approved bidirectional
amplier (BDA) may also be installed to further enhance
in-building coverage from your vehicle. The XBDA is in-
stalled in series by using a 3 metre (10’) length of RG58A
connected to the output of the mobile charger. The
XRMA antenna then connects to the output of the
XBDA. Only qualied radio service personnel should in-
stall a BDA so as to ensure the effective radiation level
remain in full compliance with regulatory requirements
in your country of operation�
In the event of a damaged or lost antenna, only original
replacements should be used so at to not compromise
the units type approval certication.
The antenna on the speaker microphone is a unity gain
ground independent antenna to ensure the maximum
multi-directional range. The mobile charger output pro-
vides a reverse polarity sma female antenna connec-
tor as does the XBDA.
