oftheoutdoorantenna
1. Pleaseunderstandthatthephysicalpropertiesofradiowavetransmissionarea
bitlikethatoflight.Willformareflectiononthesurfaceoftheobject.The
reflectionefficiencyvariesaccordingtothematerialoftheobject.Metalobjects
reflectthemoststrongly.
2. Insomecases,thesignalfromtheoutdoorantennawillbereflectedtothe
indoorantenna,causingoscillation.
Theverticaldirectionfrontradiationmainbeamangleisabout60degrees.
