Alan Dick to Show Dipole Antenna, Notch Filter
According to Alan Dick Broadcast, its ADB-VP vertical dipole FM broadcast antenna (pictured), particularly suited for HD Radio and analog broadcasting, is a vertically polarized broadband FM side mount antenna consisting of a balun-fed vertical dipole, power divider, coaxial feed lines and featuring symmetrical band-pass. The company will feature it at the upcoming NAB Show.
Constructed of stainless steel with a brass inner conductor, all associated brackets and hardware are made of hot dipped, galvanized steel. The unit, says the firm, is assembled full size and factory tuned on an electrically similar tower structure to insure proper impedance match and low VSWR.
The company’s ADB-CNQ coaxial quarter-wave notch filter is designed for suppression of intermodal products and rejection of a single frequency. ADBL points out that its filter family also features natural temperature stabilization, low insertion loss and VSWR packaged in a compact, high “Q” aluminum cavity. The filter’s small footprint, it says, allows it to be mounted virtually anywhere in a transmission system.
ADBL will exhibit at the 2013 NAB Show with Jampro Antennas.
