RFD-RFD900X WITH MULTI CABLE MODEM BUNDLE

General

The RFD 868x Modem by RFDesign is a ultra long-range RF modem with 1 Watt transmission power. This enables ranges of up to 40km (Peaks: 80km demonstrated by Edge Research labs on a balloon !, 57km in India, on Dipoles). The software "SiK" is an Open Source development. A Boot Loader and interface are provided for adjustments of model firmware via a serial port.

Features
