Two back-to-back 75-300 ohm transformers make a perfectly good isolation

In my experience that used to work. I tried that with several "newer" balun transformers only to sill have the issue. I smashed one open only to find that one of the twinleads on each balun was grounded to the F connector. I use an actual made-for-cable iso transformer.
