# RFD900 Long-Range Telemetry
|
|
|
|
[jDrones](http://store.jDrones.com) and [RFDesign](https://rfdesign.com.au/) offer _long-range_ [SiK](../telemetry/sik_radio.md)-compatible telemetry radios.
|
|
The radios provide reliable connectivity at greater than 5km ranges with normal antennas (and have been reported to achieve much greater ranges).
|
|
|
|
|
|
|

|
_jDrones_ have productized _RFDesign_ modems (added a casing with power management, filtering and other electronics inside, along with cables to connect to popular flight controllers, and individually validated antennas).
|
|
The first such modem was the _RFD900_, but both _RFDesign_ and _jDrones_ have since iterated to new versions.
|
|

|
|
|
|
The _jDrones_ radios have a JST-GH connector, and come with cables for: _JST-GH to JST-GH_ and _JST-GH to DF-13_.
|
|
They can therefore be used in a "plug-n-play" way with most [Pixhawk Series](../flight_controller/pixhawk_series.md) controllers (you might have to change/use an appropriate connector for some "non-standard" boards).
|
