Primary Antenna
The primary antenna connection on the 819-GPRS is a female connector, therefore you must
purchase an antenna with a SMA male connector. Do not select a SMA antenna with “reverse
polarity” or RP-Male. When using a direct mount or “rubber duck” antenna, choose the antenna
specific to your band requirements. Mounting options and cable lengths are user’s choice and
application specific.
