I am not sure whether my antenna is broken or it is meant to be like this. Please help me out  Head Scratching Help Me
Is it a friction fit and the coaxial wire does not touch the metal attached to the sma connector?
Very confused. I just noticed that there was a gap in between them.

Looks like you dismantled it at the WRONG JOINT.
Tx will still work, but NOT SAFE TO FLY.

FrSky DFT module in my Hitec Optic 6.
Replaced original 72mhz module to convert to 2.4ghz.
DFT plugs right in without any mods.
Antenna is however at the bottom, haha
(DFT for Futaba, Hitec, DJT for JR)

Thank you sir.
Is it for the purpose to avoid Futaba Transmitter to Futaba Receiver ?
So, we us Futaba Transmitter+Frsky DFT+Frsky receiver.
What is the advantage ?
Sorry for my dumb questions.

@manojswizera
No range problem in a year of use.
Just have to move the antenna a little outward with the little finger...

I remember seeing a video of modifying the case to move the antenna to the top. Don't think it worth the effort.

I don't know enough about replacement antennas to answer that. Sorry.
You'll have to ask some of the electronics gurus on the forum.

Aditya you would need antenna with an rp-sma connector, the one you have selected has an sma connector
Something like this

http://www.ebay.co.uk/itm/REPLACEMENT-WIFI-WIRELESS-ROUTER-AERIAL-ANTENNA-RP-SMA-/400599110107?pt=UK_Computing_Boosters_Extenders_Antennas&hash=item5d459151db

or

http://www.ebay.co.uk/itm/2dbi-Omni-Directional-WiFi-Wireless-Antenna-Black-2-4ghz-RP-SMA-Connector-/221369030726?pt=UK_Computing_Boosters_Extenders_Antennas&hash=item338a9f5846

EDIT: On second thought can you put a pic with close up of the connector either on the module or antenna, cannot exactly make out if its sma or rp-sma.
