Please see the More Details and the Quick Start Guide links for each endpoint. There is good product-specific antenna related information, including recommended antenna positioning when applicable. (A link to the QSG is typically found near the bottom of each endpoint product page.)
See the Antenna Performance section above for general information useful for optimizing how the product’s antennas are used. For an additional specific example of good general practice for positioning direct attach antennas, see How to Position 1200M Antennas.
