Default Re: Cable impedance upper limit in Radcom Plus?

We used 328 Ohm Zo balanced lines on HF broadcast transmitters, and there would be matching sections inserted of 400 Ohms Zo or so, maybe 440 Ohms Zo on the phasing verticals to the end-fed dipoles, all which actually matched the transmitter to the aerial, satisfying the 'traditional' line equation, the Smith chart, and any VSWR / reflection coefficient metering. And because it all works, theory translating nicely to practice, there is no reason to doubt what we were taught all those years ago.

So have we missed something?
