Flexi BTS Mounting Shield Quick Guide This guide can be used as quick reference for Flexi Mounting Shield (FMSA/FMSB) installations. Flexi Mounting Shield (FMSA/FMSB) is an outdoor shield for a stacked Flexi BTS. Used instead of the plastic front and rear covers, it provides protection against solar load, large insects and slight vandalism. In addition, you need Flexi Mounting Kit Floor/Wall/Pole (FMFA) in all installation cases. Flexi Mounting Shield 6U (FMSA) provides installation space for up to any two Flexi 3U modules and the plinth (6U in total). It is installed on a pole or wall. Flexi Mounting Shield 18U (FMSB) provides installation space for up to any six Flexi 3U modules and the plinth (18U in total). It is installed on the floor.
