Re: Is it possible get a tension on N connector in RX mode for external preampli for vhf / uhf ?

You can make your own Bias Tee.  See this link:

I would build a Bias Tee in a metal box because of noise pickup, or radiation on a transmitter cable.

There are more links at the bottom of the above web page link.

For a receiver bias tee, a ceramic capacitor would be a good choice.  For a transmitter Bias Tee, I would use 3 or 4 ceramic capacitors in parallel to handle the current, and not overheat.  A ceramic doorknob for a transmitter cable would be best, if available.
