Antenna selection chart
The antenna choice and position directly controls the system range. Keep it clear of other metal in the
system, particularly the 'hot' end. The best position by far, is sticking out the top of the product. This is
often not desirable for practical/ergonomic reasons thus a compromise may need to be reached. If an
internal antenna must be used try to keep it away from other metal components, particularly large ones
like transformers, batteries and PCB tracks/earth plane. The space around the antenna is as important
as the antenna itself.
