DJI LightBridge – Long Range HD video transmitter

DJI LightBridge - Long Range HD video transmitter

Continuing the drone copter theme (although this product will most certainly have other uses), the DJI LightBridge is a digital transmitter, capable of carrying full HD video of distances up to 5km (3.1 miles).

The DJI LightBridge uses 2.4G RF technology, transmitting up to 1080 30p video. The standard 5dbi omnidirectional antenna has an affective transmission distance of up to 1.7km (1.05 miles). The above mentioned 5km distance is in reference to the optional 14dbi antenna.

This could be considered a big game change for some; a digital transmission is fair less prone to interference than an analog source.

The transmitter takes composite and HDMI in, outputting HDMI and USB; the latter for use with mobile and tablet devices.

The sky end of the device weighs an impressive 70g, which for reference is just shy of the weight of a GoPro 3+ without it’s housing; great for compact low weight carrying drones.

No pricing information? There are plenty of long range HD video transmission, the problem it cost an arm n leg…

This is not at all a feasible solution for a Phantom. A Phantom with gimbal and gopro is already pushing the payload limits of the quad.

Recommended take-off weight is <1000g, but a Phantom with gimbal, gopro, and traditional FPV Tx is approx 1150g. This Tx weighs double a typical Tx, taking the quad to 1200g, then a second battery since flight times are now down to <5min.

It's just too much. Nice for bigger hex and octos, MAYBE okay for a F450.

I'd be more interested in this for land based use.

Will this conflict with DJI 2.4ghz blutooth groundstation used with iPad?
