How do I implement an external antenna for the M20048-1?

According to the M20048-1 datasheet, "External Antenna Support: A low-cost external circuit can be used to provide

external antenna support. Please contact Antenova for more information, and

example circuit." Can you provide external antenna support?

Thanks Yu Kai Yeung. It looks like the intended external antenna type is active. Can you provide a recommended active antenna. Lastly, is it permissible to replace the active antenna with a passive antenna + LNA?
