K6STI 50 ohm to 75 ohm Matching

If you play with FM stereo receivers these matching networks may be useful.

"...Most signal generators have an output impedance of 50Ω. To align an FM tuner or measure its performance, it's best to match this to the tuner's 75Ω input impedance. Mismatch loss is only 0.2 dB, but a source impedance that differs from the design value may alter the RF input circuit bandwidth or resonant frequency. This can degrade front-end tracking and affect intermod or desensitization measurements.....".
