U_LINK 433M Extended-range FPV Tuner Amplifier Full Frequency
Item Name:U_LINK 433M Extended-range FPV Tuner
Transmit Power: 1W @ 30dbm
Receiver channels: 8 channels
Remote control distance :10-45 km
Input voltage 7-14 V,current: 12V 250MA when approximately so
Frequency: ultra-wideband frequency hopping, frequency range from 420-470M.
Features:
1).New growth with RH-771 antenna,support two kinds of transmit power optional:500mw and 1.4w.
2).1.4w will need more power.
3).RSSI output: Output packet loss rate, the output voltage is 0-3.3V, compared with RF field strength display more objective.
4).Supports two kinds of input formats: PPM or PWM mode (forward mode) suitable for all model aircraft remote control on the plane
5).Fail Safe: no signal output after 1.5 seconds out of control, out of control position to support power-down save for FPV runaway protection.
6).433 most cost-effective remote control system , with a special high-efficiency 1 /4 wavelength transmitting antenna.
7).Transmitter power is 1W, using homemade 17 cm small antenna can reach more than 20 kilometers,the electrmagnetic environment under good conditions,can reach 30-40 km.
Package Included:
1 x U_LINK 433M Extended-range FPV Tuner
Connection Instructions:
1.G——(GND):Ground wire, connect the cathode of the battery which is provided three by U_LINK
2.V——(VCC):The nput power of icut cake,it's voltage is 7-14V which connect the anode of the battery
3.P——(PPM):Connect to the PPM signal wire
4.——The output of 5 v power supply to the anode,no need for ppm model
5.1—8:Forwarding mode 1-8 channel input
6.S——Transmit power choice
7.D——Download
Instructions:
1).Be sure to check whether the transmitter antenna connected.Transmitter must have an antenna to boot,or easily burned.
2).Transmitter antennas are generally more than 1.5 meters from the ground,the antenna must be perpendicular to the ground.
3).The receiver antenna mounted perpendicular to the ground plane! Otherwise there will be dead long-distance flight,you can use a wooden stick,plastic rods support up, butdo not use carbon rod.
4).Transmitter power is between 7V-14V,recommendations 3S lithium battery. Do not check the voltage before using too low.
5).It is recommended to use PPM mode,PWM mode, the transmitting antenna 433 exists the possibility of interference with the receiver, try to pull the 433 recommended by thetransmitting antenna and 2.4G receiver distance, reasonable layout to solve.
