Ok, thank you audioguru and Hero999 for your advises.
I found something, a TV transmitter kit (UHF) :
http://www.ermes.free.fr/kier134.pdf (the documentation probably doesn't exist in english, sorry).
Maybe I will try this and see if with a signal amplifier I can reach my expected range. -
Wow, the difference between a simple audio transmitter and a video transmitter is so large ?
Hum, maybe I have to find another solution for the onboard camera.
One last question : if I want to increase the frequency on the FM transmitter (more than 108mhz), I have to change only few components (adjustable capacitor, coils) or this is too complicated ?
Thanks again for your time ;D -
Thank for your answer.
If I understood, I need an AM transmitter, working on a higher band (around 200MHz, TV band) and in this way I can use a conventionnal TV with his tuner to receive the signal.
But I have little knowledge in electronics, how I can modify the schematic for this use ? -
Hi everybody,
I was looking for a way to transmit video on a long range, 15-20km (10 miles) ; I need this for a UAV project, or model aircraft with a onboard Tv camera.
But I found only too expensive or too heavy materials.
When I saw this :

I thought, maybe I can plug the video RCA from the onbard camera instead of a microphone, and use a simple FM receiver plug on my AV enter from my TV.
So there is my question : can I use this transmitter for a Tv camera ? is there enough bandwidth on the FM radio band ? do you know an other easy schematic, for video transmitting with enough power ?
Thanks you ! :D

I planed this too, give more power to the transmitter, or add a small amplifier.
