Power Line Antenna II


Superior Frequency Range & Improved Voltage Protection

Power Line Antenna II hardware

The CTL-SystemWare Power Line Antenna II (PLA II) offers unmatched performance, user flexibility and an extremely wide frequency range. With an RF spectral coverage of 1kHz to 1.25GHz and voltage protection up to 480VAC, PLA II addresses the increased threats caused by the technological improvements in carrier current devices and power line and conductor infrastructure. The PLA II, designed to operate with CTL-SystemWare’s full complement of RF sensor products and software, can also be utilized with generic spectrum analyzers or software defined radios of your choice. Equipped with Ethernet, USB, manual controls and embedded browser support, the PLA II allows the user to automatically cycle between conductor pairs during a sweep or manually when used as a stand-alone unit.
