The selection of a proper GPS antenna for a GPS tracking system is very important. The main criteria to keep in mind when choosing a GPS antenna to work with your Raveon M7 series GPS transponder is:
- Amplified. The antenna must have a build in RF amplifier that will operate off of 3.3V DC. The power for the GPS antenna’s RF amplifier is feed down the center-conductor of the coax-cable going to the antenna.
- SMA connector. The RF connector for the GPS antenna is an SMA type connector. The cable will have a male connector on it, and the M7 has the female.
- Proper Mount. GPS antennas are available in many different mounting configurations.
- Proper Environment. Some antennas are designed to be mounted on the roof of a car, others are suitable in salt-water environment and others are not. Consult the manufacturer for information on temperature range and environmental restrictions.
