The Twinax is shielded twinlead. Like your 300 Ohm twinlead with a shield. It could be useful in some situations.

It probably could be made to work for a half wave loop balun. but would require some unconventional considerations.

In general, coax is better for the half wave loop.

---------------

Referring to the 0064 with half-wave balun in previous image.

The input & output of VHF portion was disconnected and powered down.

There is some noise figure advantage in not having a VHF circuit connected to a UHF circuit.

Anyhow, that balun would not work well for VHF.

FYI, will not be logging in frequently for a while.
