I agree with Kevin. Tha same could be said for the RCA (phono)

Was it tuned correctly on a network analyzer, or tuned to pass and reject

Any special reason why you would want to? LDF4-50A is the most common and
easiest to find connectors for. LDF4-50A also has half the loss and would be
more durable. The LDF1-50 might be good for jumpers with small turning
