Revolutionary dual-band transmitter design with fast switching greatly extends channel coverage and brings more possibilfes. Eficient PA and power calibration to power consistency across all channels. Aluminum alloy triple shel structure and large centrifugal fan provide suffcient heat dissipation. Frequency band:4990-5200+5362-5945MHz Frequency precision:200KHz(Typ.) Channel customer:8+48CH SIN(For 3MHz) 70dBc Modulation type:FM Antenna Port:SMA 50 Ohms Frequency control:PLL Video input level:1V0.2Vp-p(typ.) Frequency stability:100KHz(Typ.) Operating Temperature:-10-+70 Power Supply:DC 7-30V Control Protocol:IRC Tramp Wiring& Settings: The antenna must be installed before use! The kit not contains antennas! The frequency of the antenna must correspond to the SMA interface definition! Controlled using a single button, the button integrates RGB lighting,blue for band, red for channel, and green for power level. When there is no operation. theRGB LED blinks cydically. the number of times the RGB blinks represents the current VTX status (when the green LED is always on,the VTX enters PITMODE). Long the button to enter VTX setting. at this time the RGB lights are lit altemately. release the button under the corresponding color light to enter the corresponding function seting. At this time, short the button to adjust the value. For setup via the flight controller, connect the DATA pin and use the IRC protocol. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use. Color:Black Material:Metal+Plastic Package Contents: 1 * Video Transmitter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
