Appendix C
Antenna Specifications
 Table 14: Recommended Geodetic Active Antennas
The antenna gain should be selected depending on the cable loss between the antenna and the receiver. Prices 
and availability can be found in the latest Price List on our website.
C.3
Active Antenna
Lower cost antennas for higher volume applications or for more cost sensitive applications are available.
L1 GPS receivers are manufactured by implementing a 20 dB LNA on board. For this reason, an active +12 dB 
antenna is more than adequate. An antenna with +26 dB to +36 dB may overdrive the RF input of the L1 GPS 
receiver if it is used with a short cable between the antenna and the receiver. Table 15 lists the active antennas 
which could be used with any of the L1 GPS receivers.

C.4
Passive Antenna
For DGPS applications where <1 m accuracy is required, it is strongly recommended to use an active geodetic 
GPS antenna if possible. In the event where the cable length between the receiver and the antenna is very short 
(less than one meter), a passive antenna could then be considered. Table 16 on Page 59 lists the specifications 
for recommended passive antennas.
