Range
The antenna choice and position directly controls the system range. Keep it clear of other
metal in the system. The best position by far, is protruding vertically from the top of the prod-
uct. This is often not desirable for practical reasons and thus a compromise may be needed.
Note that the space around the antenna is as important as the antenna itself. All radio sys-
tems are dependant on a radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmos-
pheric conditions.
Range is affected by many things, for example local environmental conditions, atmospheric
conditions, interference from other radio transmitters. For evaluating the local environment
please see our RF Meter (DS006)
In very worse case applications the range quoted may be reduced below 30% of the optimal
range stated.
Recommended Antenna
The BEAD Antenna provides a Miniature PCB mounting solution
where a high performance is required from a small space .
Available as straight or 90 degree mount this antenna is a gen-
eral purpose omni-directional. It measures 8.5mm long, Dia 7.
