ALP Series II. Low and Medium Power UHF Television Antenna. Features

Transcription

1 Features All CCIR bands IV/V channels available Lightweight/low wind load Easy to install with less expense Radome enclosed for environmental protection: long life, low maintenance, and reliability Power ratings up to 28 kw (peak)/ 12 kw 8VSB available Customized patterns optimizes coverage for your market area Wide selection of off the shelf patterns with simplified application process Patterns measured at factory for reliable performance in the field and superior coverage The ERI ALP Series II antennas deliver the versatility, power, and reliability that are the keys to success in today s competitive broadcast marketplace. For full-power stations transitioning to DTV, ALP antennas offer field-proven solutions. Broadcasters with medium power requirements can benefit from this antenna s lightweight, low windloads, and easy installation which provide reductions in installation time and costs. For Low Power Television (LPTV) stations the new, higher power handling capabilities of the ALP UHF antennas make them the ideal choice for the higher ERPs now allowed for LPTV stations and translator facilities. The ALP antennas offer the quality and performance needed to improve coverage and maintain competitiveness in today s broadcast marketplace.

Mounting Brackets Required Channel Number [L] Length, Inches (mm) (3048) (2896) (2743) (2591) (2438) (2286) (2134) 6.0 in (152 mm) 5.0 in (127 mm) 5.0 in (127 mm) 1.0 in (25.4 mm) Dia. Hole Ordering Information The example antenna is a low power version of a 16 bay, horizontally polarized, omnidirectional antenna, with a beam tilt of 0.5, for channel 34. Wide band antennas are specified similar to standard single channel antennas, except the applicable channels and bandwidth of the antenna are specified in the final three digits as follows: The first two digits represent the number of the UHF channel at the bottom of the band requested. The third digit represents the number of 6 MHz channels covered (5 for 30 MHz bandwidth or 3 for 18 MHz bandwidth). For example: ALP16L2-HSOC-425 The example antenna is a low power version of a 16 bay omnidirectional antenna, with a beam tilt of 0.5, which covers channels 42 through 46 (30 MHz).
