[TG] [TG11] Ais 700 "saw "targets only 0.3 nm range

[toniocask]

Hallo, my ais 700 interfaced with my old raymarine c80 was always fine, targets visibility at 10/12 nautical miles. Last week the system shows me only a range of 0.3 nautical miles ais target. I was thinking was the antenna whf on the top of my mast, I changend the antenna with a brand new Banten one. Nothing is change. My whf is a foruno and it work fine. I have also done the diagnostics with the pro ais, all is marked "green" and also the light on the ais 700 is green.
What can be ?
Thank you
Antonio
