Hello:
I´m Jesús, I´m from Spain, and I´m designing a small UAV for my university. But, know I have a big problem :( I need a video or video/data tramisition system that fulfill the following requirements:

1- Low weight (less than 300gr if only transmit video, or 500gr if it can transmit video (like a video transmiter) and data (like a radiomodem) at the same time.

2- Operate at 14 volt maximum

3- S-Band, L-Band, ... whatever (best L_Band)

4- We need a range of 10km with omni-directional antenna.

5- Compatible with procerus UAV kestrel autopilot.


Thanks For your help.
Jesús

We have used the following Global Microwave Systems Inc (GMS Inc.) video transmitters (L-band) and these appear to be the best on the market (and only a mere 28 grams!):

They also sell 1w-50w output amplifiers, depending on your transmission/range requirements (Our 2W amp only weighs another 25 grams!):

The matching receiver we use is this model:

We also use their helical antenna system for exceptional tracking/reception:

These can cost a bit more than other/cheaper video transmitter but as they say, "you get what you pay for". We use the Kestrel (900mHz) and GMS video tranmitter (1.7Ghz) together with no issues. Adding a band-pass filter GMS sells also improves reliability when using two high power transmitters together on the same platform (Kestrel/Xtend modem and GMS video transmitter)
