All things pertaining to wireless and RF links

Hello!

I've just bought some of the NS73M FM Emitter, but I have some doubts about it.I've made a little PCB to place it and start playing, but I'm not sure of two things: the crystal position and the antenna, since datasht is not very clear in both aspects.

- Is the crystal (not using clock, just crystal: http://search.digikey.com/scripts/DkSea ... -1002-1-ND) well positioned in the schematic shown below?
- What kind of antenna is recommended for this device? (it needs to go inside of a case)

Thanks for your help! :)
