1 AL PLUS Series Features Fast delivery Light weight, low windload Quick, low-cost installation Four azimuth patterns available Up to 10 kw DTV (23 kw analog) input power rating 8- and 12-bay models Multichannel versions available Characteristics Frequency Range MHz (U.S. channels 14-69, European channels 21E-62E) Operating Frequency Specify by channel number or frequency band Input Impedance 50 ohms Input Type 1-5/8 EIA for low power and 3-1/8 EIA for medium power VSWR 1.10:1 over single channel Beam Tilt 1.75 degrees for 8-Bay, 1.25 degrees for 12-Bay Low and Medium Power UHF Antenna Systems Now television stations have a cost-effective solution for their digital and analog requirements with the new AL PLUS Series broadcast antennas from ERI. With a low cost to purchase, install, operate and maintain, this antenna is an ideal interim solution for many stations looking to meet the FCC s minimal DTV facility requirement as well as the perfect choice for low power NTSC services. The AL PLUS Series is a horizontally polarized UHF antenna. Incorporating advanced ERI TRASAR technology, the AL PLUS features a reliable, end fed design for maintenance-free operation. Developed to handle up to 10kW of digital power (23kW analog), they provide Effective Radiated Power (ERP) levels up to 450kW (1MW analog). Designed to be compact and lightweight, the AL PLUS minimizes tower loading and simplifies installation.
