PCB Keep-out areas: Apex LT
Dimensions in inches. Tolerances = +/-0.005” unless otherwise noted.
For optimum antenna performance, the APEX LT modules should be mounted with the PCB trace antenna overhanging
the edge of the host board. To further improve performance, a ground plane may be placed on the host board under the
module, up to the PCB edge. The installation of an uninterrupted ground plane on a layer directly beneath the module will
also allow you to run traces under this layer. CEL can provide assistance with your PCB layout.
