Antenna Selection:
The output power of the board is 2W, so the antenna cannot be a wire or a telescopic antenna. Use a standard transmitting antenna with a VSWR less than 1.5 (GP antenna is recommended due to its low price and easy application), because using a non-standard antenna may damage its power tube (the telescopic antenna and wire antenna have no VSWR). Even without damaging the power tube, the FM transmitter board's working distance will be shortened. Also, the higher the height of the antenna, the farther the working distance will be. In actual use, its transmission distance is affected by many factors, such as feeder length, antenna gain and use environment.

Package Included:
- 1 x FM Transmitter Board

Note:
- Remote control and other items mentioned above are not included.
