Difference Between the VHF Antennas Used with the DC/T/TT/TB Collars

There are two antenna options available for the dog tracking and training collars. By default the longer antenna (22 1/2") will be installed on the device, while a shorter antenna (18 1/2") will be included in the box. The longer antenna should provide the best performance, although it may be necessary to switch it out with the shorter antenna.  

When using the shorter antenna tracking performance will be lessened for the collars.  Choose the appropriate antenna to allow for maximum performance with minimal impact.
