Received Signal Strength Home

---

Three factors determine the strength of the signal heard by the searching beacon.
1) Distance of separation
2) Beacon Orientation
3) Volume control setting.

	1) The strength of the signal recieved by a searching beacon is directly propotional to the distance seperating it from the transmitting beacon. The greater the distance the weaker the signal.
PageTop 2) The relationship between the transmitted signal from a buried beacon to the alignment of a searching beacon is called a beacons orientation. Beacons have antennas aligned along their long axes to detect and transmit signals. The strongest signal a receiving beacon can get at a given distance occurs when it's antenna is aligned parallel to the transmitting beacons field. The weakest signal at a given distance happens when a receiving beacons antenna is perpendicular to the transmitting beacons field. The field generated is three dimentional. The searching beacon must be oriented in three dimensions to receive a maximum strength signal .

	3) All modern beacons have a volume control which allows the searcher to amplify the signal recieved from a transmitting beacon. The higher the volume setting the larger the bracket size. Make every effort to turn the volume setting as low as comfortable for the searcher. This decreased sensitivity of the receiving beacon makes the shortest posible bracket length at a given distance.
