WISCO International (Maxrad

The MDA UHF Series features soundly constructed lightweight dipole arrays for UHF frequencies. They are available in 1, 2 or 4 bay models. The 2 bay antennas provide 3dB or 6dB gain while the 4 bay antennas provide 6dB or 9dB gain, with gain being dependent on either omni-directional or elliptical mounting. Mast and phasing harness are sold separately.
