Replaced Flightaware antenna with Active Diapason Clone

Great it has been working for you guys. I got a similar clone with a bias tee and I get mostly zero planes. I have been a laying with gain settings and sometimes I may get a single plane on the screen. If I switch back to my old passive antenna I get more planes almost instantly. The tee is being powered by a modified USB cable and lights up. Any help would be greatly appreciated!

Take a look at this post, probably you are overloading the dongle or there is something wrong with your bias T.

The only difference I notices is the lengt 210mm (original) v.s. 160mm (clone).

@bramjacobse Did you noticed a huge difference? Your post doesn’t show a before and after. How did you mount the clone into your mast? You’re a few miles north of me :wink:

How much did you lower the gain to compensate for the amplification in the active antenna?
