120KM Long RangeRMILEC T4047NB20 NB20 20 Channel 5W 433Mhz UHF System w/Receiver for JR/Futaba Radios
Instruction:
NB20 system adopts the latest RF technology, providing very high adjacent
channel rejection ratio and anti-blocking performance, which gives rise to the
outstanding anti-jamming capability of the new system. NB20 receiver can detect the
frequency and amplitude of EMI interference with unbeatable accuracy and precision
based on the extremely low self-noise of -125dBm. The RF performance of NB20
system surpasses the older 4047 systems several orders of magnitude. Furthermore,
NB20 system takes high-speed processor for signal acquisition and output with very
high precision. Its high efficiency transceiver can make full use of band width
limitation and spend shorter time to work out data exchanging,and frequency
calibration. As for operation, NB20 system is compatible with any receiver to
construct a signal relay system. It is highly compatible with mature products on the
present market, such as FUT, JR, HITEC, TDF, FS, XINYI etc. There is no need for
consumers to change the old remote control system or any parameter settings to
directly extend the remote control range. PWM output-and-input is one-to-one. It can
relay signal with very high precision. By using the powerful forwarding of 20
channels, UAV's parameter can be adjusted in the air, and the aerial cameraman and
pilot could work together with single radio. In addition, one transmitter can be shared
by several operators. As for the receiver, either EMI or RSSI signal can be displayed
on LED, which allows debugging according to the visual signal strength. The new
system is of longer remote control distance and higher reliability, because the source
of interference can be more quickly and accurately ruled out.
