3meter 3dbi GSM antenna
In stock
This is Magnetic Mount Antenna having a frequency of 2400 – 2483 MHz and gain of 3dBi. This is very helpful for signal boosting. Magnetic mount antennas are commonly used for car and truck applications. The antenna’s magnetic base sticks securely to the metal of the vehicle. The metal surface of the car acts as a ground plane to bounce the signal. Since magnetic mount antennas require a ground plane, they should be mounted on metal.

- 3S 11.1V 12.6V 40A 18650 lithium battery protection board (comes with recovery function-AUTO Recovery).
- Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650.26650, a polymer lithium battery).
- Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use).
- Continuous charge current (upper limit): 20A.
- Suitable for the drills with starting current below 80A, power 135W below.
Note:
- The Successful start of the drill requires a three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 cannot start the drill!!).
- Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
- When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above25V, capacity 10uF-100uF) to the motor’s positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
