Review on Superbat PL 259 Digital Antenna Analyzer by Cynthia Guarente

I bought this to replace an older, slightly longer coaxial bridge between my RF transceiver and antenna tuner. I used it straight away on the 80-100 watt HF bands. The cable carried so much radio frequency that it caused local devices (computers, etc.) to behave erratically or simply shut down. Reinstalled the original coax jumper and everything worked fine. My recommendation: Do not use or buy to connect HF radios. They might work well for low-power devices (less than 5W), but there's significant leakage at 50+W.
