Video camera/receiver directional antanas

[motomaniac1988]

I am currently working on an airplane project with a front mounted video camera and I was wondering a couple things. First of all, I have a problem with the transmitter/receiver hook up and keeping them inline with eachother. Does any one know how to make a transmitter antena that doesn't need to pointed directly at the receiver, or a receiver antena that doesn't need to pointed directly at the transmitter, or a 2 in 1 combo?

I also had another thought and it involves the sport of hockey. inside the pucks are microchips which emit a ignal allowing the camera to stay "locked on" to the puck. Does anyone know how or where I can find this kind of setp and apply it to an RC camera????

Thanks, David

Is your wireless system an economy Far East product? What antennas are you using now?

I'm using a low power (50mW) Lawmate Tx with dipole and the matching high gain Rx with a home made patch antenna (which is "directional"). I don't have to aim anything as I fly around the field and drop outs rarely occur.

My point is that you may be trying to fix the problem the wrong way. Perhaps your Rx has poor performance or the Tx/antenna installation is not optimized. If you are using a whip antenna on the Rx then that must go.

The systems I have read about were very visual. Typical systems are IR based. The puck was a special color and/or had several IR light emitters. Placed around the arena were several optical sensors. Some serious computer horsepower and video processors, did the rest.

As far as a tracking antenna goes, this thread mentions a successful DIY system: http://www.rc-cam.com/forum/index.php?showtopic=15
