Topband: Ground loop isolator that passes DC

[Chuck Hutton]

Hi -

Many years ago I saw some ground loop isolators that pass DC.

That is exactly what I need so that power can be sent over coax feeds to  preamp at the antenna.

 I cant find anything on eBay that mentions passing DC in an isolator. None of the isolators I have will pass DC.

Does anyone know an isolator that passes DC? I would like to avoid building one.
