What is the RMILEC NB20 UHF LRS radio system?

A Relay System

The RMILEC NB20UHF LRS Radio System is essentially a relay system for radio control and a Long Range System (LRS) 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!(Selectable)

 

What is exactly special of NB20?

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.

What’s more, 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.

 

NEW VS OLD

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.

 

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, which

leads to scan interfering frequencies of on board equipments in detail to select

frequency band with lowest background noise.
