The Extended Range Antenna is a uni-directional antenna that gathers signal from only the direction that it is aimed. This antenna can easily convert one bar of signal into a usable signal strength for operating your Hogg Boss control unit. It is extremely effective and is the preferred method of signal improvement for the USDA and Wildlife Management agencies. We use only Wilson Electronics antennas, the best in the industry! The antenna requires a mounting pole which we recommend using 3/4 EMT conduit 10-20 ft long. This antenna can be adapted to use with many cellular trail cameras as well.
