Amateur TeleVision

This page will be more about the issues surrounding ATV such as my antenna installation, the control of the antennas and the RPi ATV picture generator.
On the other pages I will describe my ATV experiments on the different ATV bands. A separate page is devoted to DATV and to experiments with the ES’Hailsat.


 

 

10 GHz experiments
After many years, I finally decided to place the 10 GHz LNB on a 30cm parabolic reflector and put it out of my roof window. In Electron I read an article about using caravan clamps for mounting an antenna mast. I bought 2 of those things on a flew market for €12,- and mount them on an small closet which stays under the roof window. That was a perfect way to mount the mast (not agreed by my xyl..).

After the antenna was setup, I rotate it to get some signal on my satellite receiver. And YES! If received the signal of the Zoetermeer ATV repeater, but only B4.

After the antenna was setup, I rotate it to get some signal on my satellite receiver. And YES! If received the signal of the Zoetermeer ATV repeater, but only B4. Because it’s not so easy to use an offset antenna for receiving ATV, it’s better to mount the parabolic reflector horizontal! Don’t forget to change the polarity in your Rx to Vertical…. Because this set-up was working well, I decided to replace my Satellite TV disk by the 10 GHz ATV horizontal mounted disk and pointed it to the PI6ATV repeater. The digital reception was B5 but the analog reception was about B4.

For receiving PI6ZTM on 23cm I build a double quad antenna. I also build a very smal QFH antenna for 13cm ISS HAM-TV. See pictures below:
