Our antennas are flexible. Use the one that fits your needs. Antennas come in a 3 element yagi directional type for long signal range, and a Mini 2 Antenna for shorted range. On a truck roof, an omnidirectional whip antenna with magnetic base will point the general direction your dog has gone. The use a 3 element antenna to pinpoint the dog s locale.
All antennas come with a coax cable that hooks to the receiver.
Signal bounce is a normal feature of radio tracking in rugged terrain. To avoid signal bounce, go to a high altitude such as a ridge, where best reception will occur. Take several readings from different positions. Your dog is located at the place where 2 or more signals cross. This radio tracking method is called triangulation.
