Make sure you do not have to move the antenna before you affix it. Relocating the antenna
after will destroy the adhesive tape and you will not be able to re-attach it.
A high gain antenna can be fitted if needed. SM recommends using an FME male to right
angle Fakra D key (colour Bordeaux part number Amphenol 3FA1ENDRJ-C04-3) as the patch
lead. Positioning of the High Gain antenna should be done following the guidelines of the
chosen antenna.
