Antenna Y3 VHFγ is the most inexpensive and effective antenna for remote subscriber radio stations (up to 40-50 km) and telemetry systems, also. In the last case it is recommended to use it in horizontal polarization.
This is the most popular antenna for communication at a short distance among wireless communications enthusiasts.
