GP antenna 65-375MHZ for FM Radio receiver & FM transmitter Campus broadcast antenna stereo W BNC Q9 plug
The appearance of the antenna is as shown.
It is a more efficient FM transceiver antenna. It can also be placed outdoors. It can also be hung in the air.
Each of the vibrators can be pulled according to the transmission frequency. It is more flexible than the GP antenna of the currently available fixed-length vibrator, making it more effective to resonate with the transceiving frequency. Achieve higher transceiving efficiency.
The length of the four vibrators is 20 cm to 1.1 m. It is suitable for wider frequency adjustment. The working frequency can be adjusted from 65 MHz to 375 MHz.
For different transmission and reception frequencies, the length of each vibrator is (300/frequency) / 4 (meters), and the middle one is pulled up. The three surrounding ones are pulled downward by 45 degrees.
For example, the transmission and reception frequency is 107.3MHZ. Then each vibrator has to pull: (300/107.3) / 4 = 0.699 meters,
When you feel that the transmission distance of your FM transmitter or the sensitivity of the FM receiver is not satisfactory, connecting this antenna can have an immediate effect.
