If you are thinking about antenna mod then this must not be problem. At least less problems then with this antenna... BY-2400-06-09 has cable with standard SMA connector which can be used to connect most modiles with detachable antennas directly or with apropriete adapter (sma to rpsma)... Unlike this one which has micro connector... You may also use PRODUCT ID: BY-2400-05-10 ... but depending on module connector it may also require to use adapter.
I use the Orange RC module which has an antenna sticking out from the back. It seems quite vulnerable and it stops the radio from lying down on it's back. Someone has suggested using a different antenna and routing it through the back of the module, into the body of the radio and up into the space inside the handle. For this I need a compatible antenna to replace the stock antenna.
In this case I'd suggest to remount module stock connector from module body to tx body and connect it with cable... you can use this antenna as cable source but it's not a best choice for TX because it's very thin and thus has higher signal losses then thicker cables... I'd prefer RG58 (50ohm 5mm outer dia)

this is good 6 inch extension for antenna cable . Just check module connector match your tx connector
There are 2 similar looking types RPSMA and SMA which differs in pin or socket in central part.. as I can see on photos orange module module male connector has socket in center (SMA) ... this cable has the same connector...but check on your module to be sure
this is just simpliest half wave antenna 3dbi. It's a good idea to distantiate video TX from Video RX... but better idea is to have crcular diagram antennas (like clowerleaf) placed on the same geometrical axis as far as possible... Diagrams of such antennas gives much more effect
then distantiating onmi antennas.
