| Feb 10, 2020 at 8:59 | comment | added | Marcus Müller | Coax alone wouldn't work – you need an active component, like the rotating switch array in the article you linked. | |
| Feb 10, 2020 at 4:01 | comment | added | Mike Waters | Are you saying that coax absolutely will not work, and it has to be a symmetric balanced transmission line? EDIT: I saw a diagram of one using coax. It had a ferrite sleeve over it to eliminate common-mode currents on the outside of the shield. | |

| Feb 8, 2020 at 17:16 | comment | added | Marcus Müller | @MikeWaters stripline circulators start at ca 500 MHz afaik, and that's most of UHF :) anyway, I'd be very interested in the passive non-magnetic circulator's operational principle: My googling for W1HR circulator so far hasn't yielded anything of the likes :( | |
| Feb 8, 2020 at 15:21 | comment | added | Marcus Müller | I wouldn't be aware of any non-magnetic, yet passive, solution to the problem: coax is inherently a symmetric thing, and I don't see how you could build a circulator with that. Note: a circulator is not the same as a directive coupler! | |
| Feb 8, 2020 at 13:02 | comment | added | Aleksander Alekseev - R2AUK | Thanks for the reply! If I'm not mistaken there are several ways to make a circulator, including one that uses coax cables. However I might be wrong. | |
