Ernesto,
I suppose the easiest way is just using a relay on the end of your Beverage
and to switch a resistor on and off.
A relay is fed through antenna wire /all is descibed in ON4UN book/.I'm
using now such system /unidirectional to JA and bidirectional to S.A./ and
its working fine.In bidirectional case noise level is about 1S higher.
