Summary[edit]
DescriptionClimbers carrying out maintenance on an antenna mast for aeronautical radiocommunications in the VHF and UHF bands.jpg |
English: This mast is used only for the emission.
The antennas are of the half-wave dipole type in vertical polarization. The radiation pattern is omidirectional in the horizontal plane. UHF antennas are installed at the top, VHF antennas are installed at the bottom. This mast is guyed with shock absorbers.English: Climbers carrying out maintenance on an antenna mast for aeronautical radiocommunications in the VHF and UHF bands |
