Alientech DUO 3 -
Alientech duo 3 has a 3000 mah battery
Roc-4 Has an 8000 mah battery. (this will make your remote much heavier)
The Roc4 is less expensive than the Alientech.
Max OUTPUT POWER on the ROC 4 is 40dbm - (I don't know the significance of this), while the max output power on the Alientech is 28dbm.
I ordered the ROC-4 and will be trying it out on a Matrice 30T/ RC Plus controller setup. I already am using the Alientech duo 3 on it.
I'll let you all know if I see any significant results. Delivery through AliExpress is slow. It's made it through customs anyway.
My Hope is better penetration through trees and buildings so i can fly lower. When at 1500 ft i need to fly at 400 ft to maintain a good signal with the Alientech. I can lower it to 260ft if needed, but not much lower. I want to be able to lower the drone more , when it is a significant distance away, especially when I hear an airplane or helicopter and or my ADSB receiver is warning me. Range isn't a factor because the drone battery is what really determines range when all said and done.
Here is the ROC-4 Spec Chart
HERE is Alientechs Technical SPEC LIST:
- 2.4G Receive Gain: 12dB±1
- 5.2G and 5.8G Receive Gain: 15dB±1
- Transmit Gain: 15 dB±1
5 | Receiving Gain | 2.4G 16dB±1 | 5.2G 16dB±1 |
