    Antenna Y3 VHF is three-component Yagi antenna. Due to folded dipole usage in combination with symmetric power supply, antenna has comparatively wide operating frequency band. It is recommended for construction of array antennas with high gain factor and remote subscriber stations. Three models designed specifically for operation at frequencies with centers at 148 MHz (L), 159.975 MHz (M) and 165 MHz (H) are produced now. Antenna is produced in collapsible version for the ease of transportation.
