## **Mechanical Dimensions** 

## **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 product. 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 systems 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 atmospheric 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 Miniature Antenna 868MHz** 

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 general purpose omni-directional. Please see Datasheet ANT-BEAD-868
