Thisradiotransmitter(FCCID:A4P‐200‐0013‐01)hasbeenapprovedbyFCC tooperatewiththe
antenna types listed below with the maximum permissible gain and required antenna
impedanceforeachantennatypeindicated.Antennatypesnotincludedinthislist,havingagain

Thisradiotransmittermayonlyoperateusingaverticallypolarizedantennawithmaximumnet
gainofantennaandcableof+6dBi.Toreducepotentialradiointerference tootherusers,the
antennagainshouldbesochosenthattheeffectiveradiatedpower(ERIP)doesnotexceed4
