RMILEC T4047NB20 NB20 20CH UHF LRS Long Range RC System
The NB20 is essentially a relay system for radio control and a LRS system all in one. How does the system work? Your existing transmitter sends a signal to your receiver which is connected to the NB20 transmitter (on the ground) The NB20 takes that signal and rebroadcasts it at an impressive 2 - 5.8w!
When the NB20 system is set up to use all of its 20 available channels your models parameters can be adjusted in flight, meaning a pilot and co-pilot / aerial videographer can work together with a single radio system, In addition to this, the new system offers vast improvements in both range and reliability as any source of interference can be quickly and accurately ruled out.
The NB20 adopts the very latest RF technology, providing very high adjacent channel rejection ratio and anti-blocking performance. The NB20 receiver can detect the frequency and amplitude of EMI interference with unbeatable accuracy and precision.
The RF performance of the latest NB20 system surpasses the older generation 4047 system. The system uses superfast processors for signal transmission and acquisition which delivers extreme accuracy. The NB20's transceiver makes full use of the bandwidth limitation which reduces the time for data exchange and frequency calibration.
In short the NB20 system offers staggering performance and quality for the long range flying enthusiast and all at an affordable price.

Comparison between the new and old models
Similarities TX
The hardware operating frequency: 400-470Mhz
Use three frequency hopping.
Scan interfering frequencies before TX(i.e., Listen Before Talk).
RX
The receiver has the spectral analysis ability with the range of 400~470Mhz,Scan interfering frequencies before TX(i.e., Listen Before Talk).
which leads to scan interfering frequencies of on board equipments in detail
to select frequency band with lowest background noise.
