antenna for xbee xbp24bz7pit004

Hi; I’m newbie in Xbee, recently I purchased two modules Xbee Pro S2B p/n xbp24bz7pit004 (no antenna included) I’m looking for an antenna. which one do you recommend me to use in green houses purposes?

That version of the module has the antenna built directly into the Xbee modules PCB. IE you do not connect an external antenna to it. The antenna is already within the PCB of the module.

Thanks for your prompt replay. It’s means that if you set the module into an enclouser box it work perfectly?

As long as the box is plastic or fiberglass it would be just fine.
