Antenna Y5 VHF is five-component Yagi antenna. Due to folded dipole usage in combination with symmetric power supply, antenna has comparatively wide operating frequency band. Three different models will provide coverage for every VHF subrange: model "L" for railroad transport, model "M" for paging, model "H" for trunking communication. Antenna is produced in collapsible version for the ease of transportation.
