Helicopter is the hardest way to do FPV

I would not choose 2.4ghz for video because at the moment someone around you will power on his radio on 2.4ghz, it will scrasmble your video. Also it is not possible to fly close or in town because of wi-fi.

1.2ghz from Lawmate is the best

a 14dbi antenna is for very long range flight. Start with the standard omni antenna that come with your receiver, you will be surprise of the result on 1.2ghz. You will not need Diversity and multiple antennas. The omni will be perfect for an helicopter up to 1km and over.
the antenna is heavy, you should make a mod to the tx if you can to replace the connector and weld a wire directly as antenna.

a very small lipo is enough. 450mah should last one hour with most cam/tx setup. buy severals and replace it oftenly.

your tx antenna should be mount vertically away from metallic part

Don't fly overhouse or road with your chopper, no one want to receive a piece of metal like that on the head, it is very dangerous.
