The connector is an RCA ???!!! Like what?
IT is an RP-SMA type RF connector on the 7dB FrSky Patch.
I don't even know why I should bother to try to get Admin to look at this typo :-)
There were days when I was such a keener to help out
And one more thing - the both plates are shorted with a nut. I tried to remove the nut and measured the dB with the immersion RF meter and guess what - the antenna is more powerful as it is with shorted in the middle plates. So leave it as it is just correct the orientation.
Guys, these antennas are reversed! To be 100% sure open the antenna and make sure that the reflector (the larger metal plate) is facing up to you and the smaller plate is facing up to the model. I have two of these antennas and both was reversed. To fix the antenna you should cut the small plastic stopper which is preventing 360 degree rotation. Then glue the two plastic parts together. There is a small arrow in the top of the antenna and it should point to the model!!! And one more thing - very important - THESE ANTENNAS ARE HORIZONTALLY POLARIZED, so for best range put the receiver antennas at 90 degree in the horizontal plane.
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.
