About RFDesign RFD900+ PLUS Telemetry Radio Modem With

This Telemetry modem features diversity antennas, full compatibility with normal "Hope RF" based radio modems as used by all 3DRobotics and compatible Pixhawks, APM's, etc. Use this as the ground station radio with 2 large antennas and you'll increase by, several times, the effective range. Upgrade the radio on your aircraft to a RFD900+ or RFD900u and increase the range several times more. "Stock" Hope RF systems are only good for about 1Km, so this is the upgrade you need! Fully compatible with the 3DR Mission Planner (same as the Hope RF radios)! Long range >40km depending on antennas and GCS setup *80km demonstrated by Edge Research labs on a balloon !, 57km in India, on Dipoles. 2 x RP-SMA RF connectors, diversity switched. 1 Watt (+30dBm) transmit power. Transmit low pass filter. > 20dB Low noise amplifier, high IP3 (Updated on RFD900+) RX SAW filter. All I/O ESD protected and filtered (New on RFD900+) Open source firmware SiK (V1.x) / tools, field upgradeable, easy to configure. Multipoint software capability with MP SiK (V2.x) Small, light weight. Compatible with 3DR / Hope-RF radio modules.
