Description
GPS Antenna Embedded SMA
Embedded antenna for small, mobile applications. Basic unpackaged antenna with LNA. 5inch cable terminated with standard male SMA connector. Match it with any SMA interface cable to create a truly small GPS prototype!
This unit works very well out of the box, but the fully packaged antennas have better strain relief where the SMA cable meets the antenna housing. If you plan on using this antenna in a vibration-intensive application, we recommend you reinforce the connection with epoxy or Shoe Goo.
Features:
- Gain 26dB
- VSWR <2.0
- Voltage 3.3V +/- 0.5V
- Current 12mA
- Weight 18g
