DAB-VD for high power dipole for digital radio broadcast  

Specifically developed to be used in a pressurised system, the DAB-VD or DAB-VD-716 are high power dipole for digital audio broadcast.

Constructed from stainless steel with either a 7/16" DIN female or 7/8" EIA connector these antennas have the added benefit of being able to be used in a pressurise system. The transmit power rating is up to 5 kilowatts (7/8" EIA) or 2Kw (716" DIN Female) per bay. The adjustable tuning stubs allow the antenna to be set for any 50 MHz bandwidth you specify within the 174 to 230 MHz Digital Radio frequency range.  

When ordering, specify your transmit frequency and connector type and the dipole will be factory tuned for single channel return loss of -20 dB  with an overall return loss of -20 dB, less than 1.2:1 VSWR. Higher gain and power is achieved in stack array formations using a suitable power divider and branch feeder cables.  

Stack array package pricing is available upon request. The heavy duty stainless steel clamp assembly supplied is suitable for mounting the dipole to any round mast between 50 and 75 mm in diameter.

A medium power version with 7/16" Female DIN connector is also available upon request.

Omnidirectional UHF binary dipole array for good gain and genuine broadband coverage

The DUA4052 series of binary dipole arrays offer omnidirectional radiation patterns, good gain and genuine broadband coverage across the entire UHF frequency range 400 to 520 MHz at less than 1.5:1 VSWR.

The array is therefore ideally suited for multiple frequency transmissions at highly populated radio sites where an omnidirectional collinear antenna would not achieve anywhere near the necessary bandwidth.

The 2-stack aluminium model DUA4052-AL and stainless steel version DUA4052-SS stand 2.5 metres tall and deliver 3 dBd gain.

The design consists of 2 sets of dipoles facing in opposite directions arranged at 90 degrees.

A phasing harness is neatly concealed inside the mount tube which is fully sealed and waterproof.
