NOVALINK 433MHz mLRS Radio System Hits 138.7km Range!
The NOVALINK 433MHz mLRS radio system passed the 100km mark with flying colors at 138.7km range.
This test was performed by a direct line of sight RF path in a large city with RF noise.
Receiver setup was placed on top of a 16-meter building and transmitter was handheld at the top of a mountain. There were trees at the top which partially blocked the direct line of sight path.
Receiver setup with Ardupilot flight controller
There were a number of non-idealities in this test:
- Antenna orientation not optimal
- Antenna SWR could be better
- IPEX connector + SMA adapter
- Yagi antenna had 15ft cable
- Tx module powered from 5V USB (slightly lower power than external power)
- PCB design not fully optimized for RF path
- Electrical noise from radio (TX16S)
Expect the performance to be better with a more ideal setup.
This is just the beginning. More range tests will be performed to push the limits of NOVALINK.
