UD Wideband Cardioid Antennas
UHF Cardioid Arrays
UD WB Series (Band IV/V)

The UD wideband series of vertically polarized antennas 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 options. Refer to external document attachments for detailed specifications.  Contact RFS for more information.
