TBSWR-60K500
High Power VSWR Bridge
The Tekbox TBSWR-60K500 is a high-power VSWR (Voltage Standing Wave Ratio) bridge designed for forward/reverse power measurement and RF testing in EMC immunity setups or general high power applications. It combines the wide frequency range and directivity of a directional bridge with the low insertion loss and high power handling of a directional coupler, enabling accurate RF power measurement across HF and VHF ranges.
