Hello, just for information: current batch is still mounted backward... But moreover, the antenna and its ground are shorted (0 ohm resistance). It is the mounting screw that does this. This is only a DC short, and in high frequency it may have a reduced influence, but it's still far for perfect. I've isolated the antenna itself by drilling its hole at 3mm, using shrink tube on the screw, and a small piece of plastic blister to isolate from the nut. I'll test this soon...
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.
