Hardware Recommendations
An optional external antenna is available from SmartSynch, Inc. (see Table 6-1), or
the customer can supply the external antenna. The specifications for this
SmartSynch external antenna are listed in
Table 4-6.
Antenna Connector
The data transceiver connector is a standard female SMA connector. The mating
connector should be a standard male SMA connector.
Antenna Cable Assemblies
A variety of coaxial cable types can be used with standard male SMA connectors.
Use a double-shielded coaxial cable in noisy RF environments to provide the
necessary isolation from interference. In applications that require more than six
feet of coaxial cable, use a low loss coaxial cable.
Antenna Assemblies
The SmartSynch, Inc. external antenna assembly is a low-profile, omnidirectional
antenna that has six feet of double-shielded coaxial cable and a male SMA
connector. The antenna performs best with an additional ground plane
approximately eight inches in diameter, with the antenna centered.
