Low RFR Pylon Antenna
This line is available with horizontal, elliptical or circular polarization and is designed specifically for applications where downward radiation is a concern, such as with antennas mounted on building tops or short towers in residential areas. The new design achieves a 300% reduction in power density near the antenna. The Low RFR antenna holds the power density at all elevation angles up to 50% of the MPE limit for occupational uncontrolled areas (based on 50 kW ERP, 6-foot observer, and 15-foot CR).
Broadband CP Panel Antenna
This new antenna, which has up to a 16-kW average input power rating and covers the entire lower 700-MHz band, uses multilayer parasitic patch technology (MPPT) developed by Dielectric. This technology allows the antenna to transmit a high power circularly polarized signal, traditionally available only from a narrow band array. The antenna additionally features a low windload and VSWR of less than 1.1:1. A patent is pending on the Broadband CP Panel Antenna.
Broadband Omni CP Pylon Antenna
The new patent-pending Broadband Omni CP Pylon Antenna from Dielectric offers a low-cost, reduced-complexity solution for broadcasters utilizing the lower 700-MHz band. By using a third of the radiators, feed system and connections typically used in a panel-style antenna, the new Broadband Omni CP Pylon Antenna provides increased reliability in a self-supporting, pylon-style format. Designed with short element spacing, Dielectric’s new pylon antenna additionally features a low RFR, a VSWR of less than 1.2:1, and a low windload—reduced 40% from the typical panel antenna approach. The new unit’s design incorporates discrete, circularly polarized, truncated broadside helical elements.
New Filters and Components
Dielectric also will show a new line of low-power filters and components designed to meet the growing LPTV, DVB-H, and mobile TV markets. These filters and components will fit into standard 19″ rack-mount enclosures and can be customized to meet specific filtering requirements. The following are the new components:
1.7-GHz DVB-H DR Band Pass RF System
800-watt 700-MHz Mobile Media TEM Bandpass Filter
800-watt 700-MHz Mobile Media DR Filter
200-watt DVB-H UHF Filter
200-watt Harmonic Filter
200-watt Dual Directional Coupler
Dielectric will be introducing additions to its established line of M2M Flash Technology solutions. These condition-monitoring solutions are designed to save time and money by allowing users to access, monitor and manage equipment remotely from anywhere in the world.
They offer the ability to monitor and manage non-IT-based assets such as HVAC units, back-up generators, security access instruments, street lamps, and cooling towers. In addition, the M2M solutions can help with predictive maintenance, which can streamline operations and reduce unnecessary operating expenses.
The units in the M2M product line are simple enough to monitor lights at a cell tower or complex enough to manage and control a cooling tower at a large power plant.
