On mine the little white sticker with the radio wave was the back. Use a small screw driver to pry it open to see which side is the dish inside facing. I also used a box cutter to remove the plastic nub on the bottom where I rotates so it can rotate infinitely, but be careful if you turn too many times the wire inside can break.
Very good replacement antenna instead of the standard shipped antennas with 2,4 GHz transmitters. Bevare for the antenna leg - it is quite short if you have transmitter modul nested into transmitter body or if it is placed under transmitter body (etc. FrSky modul under T9X body).

Bringt nur eine geringe Verbesserung gegenüber der Standard Antenne. Ist jedoch wesentlich größer als diese. Ich werde sie als Ersatzantenne verwenden.
Good antenna if you point correctly radiative side towards model.
Range is really increased. I've tested it using range-testing option at FrSky module and get good range even it was at 1/30 od output power.
Radiative side is labelled with small sticker.

Great, really fit FrSky module in my Futab T9CAP. Fully increase the signal. It's 100pcnt fellworth.
