ceev faj                

Xim rau plahaum

1. Ua ntej fais fab tuag, Kom paub tseeb tias qhov kev twb kev txuas antenna yog reliably . Txwv tsis pub, Nws yuav ua rau kom tus ntaus ntawv.

2. Xyuas kom paub tseeb tias cov voltage yog tsis pub dhau ntau yam kev siv.

3. Thov them xim rau lub EMC ntawm tag nrho cov khoom electronic khoom rau koj drone.

4. Nws pom zoo tias tus antenna yuav tsum tau ntsia downward thiab khaws cov antenna kom deb ntawm cov hlau rau cov drone.

5. Nco ntsoov siv ntais ntawv antenna.

ua ntej yuav siv                                      

1. Xyuas kom tag nrho cables muaj kev cob cog rua kom raug thiab nrees.

2. Tsis muaj khoom txawv teb chaws (e.g. kua, xuab zeb, thiab lwm yam.) yuav nkag mus rau hauv tus ntaus ntawv.

3. Nws yuav siv sij hawm 15 vib nas this rau tus ntaus ntawv pib. Yees duab thiab cov ntaub ntawv tsis tau kis mus txog rau thaum tus ntaus ntawv muaj tas booting.

4. Thov xyuas kom meej tias qhov chaw uas cov khoom siv yog siv dawb ntawm lwm electromagnetic interference.

5. Thaum lub teeb liab tsis muaj zog, Koj yuav ua kom cov nyhuv los hloov cov nqe lus hais txog cov antenna.

Overview

Industry drone market is developing very fast in recent years. The fight time and distance of drones are getting longer and longer. MK22/MK55, a long-range wireless transmission system, is designed for VTOL fixed wing and other long-range drones. The system can transmit video, fight control data, gimbal tswj cov ntaub ntawv, and RC data simultaneously. With the advantage of high level intergration and powerful function, MK22/MK55 is a typical good product to meet long-range transmission requirements.

There are two frequency bands——800MHz、1.4GHz and 2.4GHz. Users can choose according to their needs. Please choose the suitable frequency band according to local regulations.

MK22 can transmit data and video to 22km, MK55 can transmit data and video to 55km, making it very suitable for long range drone.

If you use our recommend ground station, you only need one cable with connector to connect the device and your ground station.
