Video Camera: using Aurel modules.

Video Camera: using Aurel modules.

Be careful ! in France you are not allowed to transmit in realtime video from an aircraft !

You need:

  • Aurel H2-TV Channel Audio-Video Modulator
    Mod. MAV-VHF224
    225 Fr

    Description :
    Low cost CATV circuit for high quality audio-video signals, operating in the VHF Band. Input signals can be fed from videocameras, tuners, video tape players, etc, directly using the lines of the standardized output connectors (i.e. SCART), while output R.F. can be received with any standard not modified TV receiver. The Modulator is very stable in frequency and features high harmonic rejection.

  • Aurel H2 Channel CATV Amplifier
    Mod. M.C.A. 224
    130 Fr

    Description :
    Linear CATV circuit for high quality audio-video signal amplification, operating on the VHF H2 Channel. RF input signal can be derived from a Audio Video Modulator (best operation is with our mod. MAV-VHF 224). Output can be received with any standard not modified TV receiver.

  • a good and safety box (in case of crash) 18 Fr
  • Accus (2 * 9V), a free rx channel. 296 Fr
  • 2 voltage regulator : 7812 (12V) and 7805 (5V) + 2 * 100 nF 27 Fr
  • A small TV (LCD) ex 11cm TFT 1000 Fr

Conclusions :

The result is very bad with no specific antenna, maybe I should replace my 32 cm wire with something better. Distance are bad too and some polarized effect appear when you turned the device : Really BAD !
