Dragonlink has a dramatic interference over 1280 Mhz.

This filter helps immensely.

You would place it between your DL transmitter and antenna.

I have a problem with it conflicting with my dragonlink UHF. I get noise in my video when i turn my dragonlink on, if i turn rotate the dragonlink controller around 360 degrees, the interference differs, at worst, i completely loose signal, this is 2-3m from the fpv station.

Do i need filters on the uhf tx or filters on the fpv station end?

I'll note here that with my SPW antenna, i get this problem, with the homemade crosshair antenna, it works fine. No interference

Also, if i put the UHF antenna near the antenna tracker, it actually interferes enough to move the pan and tilt servos. Obviously it will never be that close, but its an interesting example of how much interference its throwing out.

Any help would be great
