Description

The Osker Block SWR-200 (often just called Osker SWR-200) is a vintage, highly sensitive Standing Wave Ratio (SWR) and power meter designed for radio amateurs. It is distinct for its dual-impedance capabilities, allowing operators to test both 52-ohm and 75-ohm antenna systems.

This item can be seen at the GCARS club house located at 85 Harper St. Molendinar, QLD.
