UD Series
UHF Dipole Arrays
UD Series (Band IV/V)

Rev : 01 | Rev date : 01 Mar 2017
The UD series are vertically polarized antennas that are complementary to the CBS series of slot antennas.
They are ideal for low power UHF TV transposer applications as well as higher power applications.
These dipole antennas are designed for broadband operation.
Construction is of aluminum and the antenna is housed within a fibreglass radome that has been designed to survive wind speeds of 240 km/h (150mph) to AS1170.2:2011. A range of dipole arrays, 4, 8, 12 and 16 bay, are designed for various gain requirements.
Dual inputs are standard on high power models and custom VRPs are available as optional extras on most models.


  • Broadband design for Digital TV or multi-channel use
  • Low power models available in 3 versions: 470 - 650MHz, 520 - 720MHz, 620 - 860MHz
  • High power models available in 2 versions: 470 - 650MHz, 620 - 860MHz
  • Designed for maximum corrosion protection
  • Vertically polarized
  • Pressurized
  • Low wind loading
