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.
