The H72 UHF TV 470-860MHz Broadband Panel antenna provides a horizontal polarised pattern. Also, the design allows for multi-channel digital and analogue TV broadcasts. Furthermore, the specification allows for a high power-rating, voltage rating and full UHF TV bandwidth. This makes it ideal for a multitude of custom and conventional antenna arrays. Input flanges with various international standards are available. Current monitoring probes are an option.
The rugged horizontally polarised construction will deliver at least a 25-year operational life. Hundreds of units are in service globally. Fibreglass radomes, constructed from custom specified coloured resin, will provide all-round environmental protection. Also, the panel, with a 72-degree horizontal beam, provides a good omnidirectional performance in a five around configuration. Vertically spaced high gain arrays on 1 to 1.1m centres provide 32x wavelength apertures.
General Array Information
Furthermore, the H-72 UHF panel is the ideal choice for use in high power multi-channel arrays. This panel provides a five around top mount or side mount system. Also, a large cross-section multi-panel wrap around array is available.
Without any pattern degradation, five panels per tier provide 70% of an additional internal area. This compares to the equivalent square array. This provides space for high power harness components, whilst also providing good internal climbing access. Internal ladders are provided. Optional external ladders are available.
UHF TV 470-860MHz Broadband Panel Antenna Delivers both Performance and Reliability.
Pentagonal steel spines or large cross-section structural steel tubes are available to support up to 20 tiers of panels. Cantilevering on the tower top is optional. Alternatively, mounting to the mast with guy wire supports is an option.
AlanDick Broadcast design and supply suitable interfaces to fit existing structures. Fibreglass infill sectors between the panels are also an option. These improve the aerodynamic loading and provide a considerable reduction in tower loading.
