Wea is selling a Patcantenna for 2,4 GHz to use together with there big Gizmo 12-22/30 recivers. Does anyone know how to make benefit from them. Can you use one patchantenna and one ordinary antenna together or do you have to have two of them? How to best mount them on the airframe and are they worth the money? Wea is not sharing much information as usual.
