14 ANTENNAS
As compared to the basic internal 1/4 wave stub antenna, the optional magnetic
mount antenna provides enhanced coverage when placed on an unobstructed area of
a vehicle’s roof and should be connected via its low loss coax cable to the RP-SMA-F
output on the mobile charger. MAKE SURE YOU FULLY TIGHTEN!
The optional multi polarity antenna provides even greater coverage in multipath non
line of sight situations. It should be mounted onto an unobstructed area on or above
the vehicle’s roof line and should always be connected via the supplied low loss coax
cable to the MWRSM cradle connector. MAKE SURE YOU FULLY TIGHTEN!
Alternatively, where approved, the XBDA bidirectional amplifier may also be installed
to further enhance in building coverage from your vehicle. The XBDA is installed in
series between the antenna and the mobile charger using a 20cm (8”) length of RG174
coax cable and a 5.2M (17’) length of LMR200 type coax to ensure a maximum of 1W
output to the antenna.
Only qualified radio service personnel should install a XBDA so as to ensure
the effective radiation level remain in full compliance with regulatory
requirements in your country of operation XBDA is not approved for CE
countries and some other markets
Keep your body at least 20cm (8”) away from vehicle mounted external
antenna
In the event of a damaged or lost antenna, only original replacements should be used
so as to not compromise the units type approval certification or performance.
The speaker microphone uses a unity gain ground independent antenna for maximum
multi directional range. The mobile charger output has a reverse polarity SMA female
antenna connector, as does the XBDA.
