Hi Claude,
 
since the SMC jack is also DC-connected to the antenna output (through an  
inductor) to power the antenna, the unit also works well if you feed 4V to 
5V  into the unit through the antenna port!
 
That can be done using an L-band-capable standard Bias-T, and  then leaving 
the SMC connector open. You may find a Bias-t more easily than  an SMC 
cable.
 
BTW: if you do it that way, the upper limit on the voltage is limited by  
the internal Linear Technology voltage regulator, so you can go way above 5V  
without a problem.
 
The unit shouldn't consume more than 25mA or so that way...
 
Bye,
Said

Hello  !

I got my unit from a local supplier, it was unused but lacked the  data, 
so thanks to Bjorn (I hope I dindn't mess up his name too much !)  for 
the download link.

My unit has option 05 "external DC  power".

So far I had no luck in finding an adapter at a decent  price.

I would rather not open the unit, so if Bob or Magnus would  accept 
selling what they have on hand, I would be  interested.

Thanks  !

Claude
