They're all out of stock... :-|
Made 2 pairs myself, not very good.

Does anyone (or any store) have any as of now? I need them for a competition in the US of A.

If not, I'll try making them with a proper jig and let you know how it goes.

I always use a made one. But sourcing an SMA connectors are like buying the CP antenna itself.

Of late I found a few SMA connectors at ebay.in which was nice. One can fabricate a few.

I've found a SMA connector guy on Lamington Road in Mumbai, they are 75 rupees each.
The problem is bending the wire into the proper shape - its too small for 5.8G

Bending the wire at 13mm is not that difficult man.

Rs 75 a piece at Laming ton Road!!!!

can I request you to send me a few I will pay for it.

SMA = The female connector, which is on the Hobbyking antennas... PM me how many you need, I'll check with the guy.

The 13mm wire is not difficult to bend - it's difficult to get it in proper shape. That, or I just need some more practice :)

I was finding comfortable to bend it with free hand since i was using a 1mm copper wire which was pretty stiff at that length. However some find it comfortable to make a bending Jig for that dimension and shape.

would be requiring this SMA Male for video tx antenna. if that is possible.

My connectors come with the body and pin separate. The pin is hollow at one end and pointed at the other. Since I need the hollow end flat to the white portion, I solder the core of the coax to the pointed bit and insert it into the hole. If you need the pointed end out, you can solder the core into the hollow bit and push it in so that the pointy bit is out. I'm not able to make out the pin in the image you posted.
