I made a small movie about ATV on 23 cm [1280MHz].
The qso is between me and PA0ASD Wim in Amsterdam.
Not many stations in Amsterdam anymore, but you'll never know that one day the activity will increase.
So do you do any ATV on 23 ? Let me know !
Best 73 from Amsterdam.

I made a TriBand antenna for 2 meter [145MHz], 4 meter [70MHz] and 6 meter [50MHz].
The design is made by DK7ZB.
There are 7 elements, 2 for 6 meter, 2 for 4 meter and 3 for 2 meter.
There is only one [1] element for a feed and so you have only one coaxcable.
This is done by using the Open-sleeve methode and one balun.
The theoretical gain is about 4 to 6 dBd so quit nice.
