Overview
1. We will now change the conventional glue stick antenna brass soft antenna, after several flight tests, the received signal better from up to one kilometer, the biggest feature is the antenna can be arbitrarily folded up easier installation.
2. Smaller and lighter. It can be placed inside the casing; also can be tied in the machine arm.
3. 3DR fully compatible design data transmission module, Air module (serial) for aircraft equipped, Ground module (USB interface) is used to connect the computer to use the ground.
4. Two frequencies, selectable 433MHz and 915MHz, the majority of domestic users with 433MHz, there is no distinction between good and bad or the distance on a different frequency.
5. Transmission distance and there is no standard, do not in order to determine the quality of products, standard 2.5dbi antenna + default parameter (adjust transmit power only to the highest) of the cases only a maximum of 1000 meters, for increasing the transmission distance, please use the amplifier
6. We do not provide any support for this.
7. Case of default parameters, transmit power is only 11, a very short distance is a normal phenomenon, adjust yourself.
8. Any two modules in the case of wireless docking, can work together through a dedicated ground station setup tool or APM (Mission Planner) to adjust the reference (or update the firmware).
9. If the configuration problem, the case of two modules can not be docked, but also need to set the Air module separately, because Air module only TTL level serial port,
So we need a separate connection to FTDI tool operation.
1. 915m frequency antenna support equipment modules.
2. Name: 800m-960m antenna
