- Page 6 1( LW2110, LW2110PK2B) Wireless Digital Transceiver ELANsat PCB layout guideline Any metal (including PCB track and holding screw) around the antenna will result in changing impedance and radiation pattern of the antenna. These two parameters are the most important for antenna performance.

RF signal between SOIC and antenna is separated to two paths: transmission and receiving (by two RF switches).

To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
