[TZ] LNBs (and other stuff) voltage

[Tom Spencer]

Or use a clip lead between the shell of the coax connector and the body 
of the jack.  The other way takes three or four hands...

It's not that hard to make a current adapter, though.  Get two F 
female-to-female connectors with the nut for chassis or wall plate 
mounting, and mount them side by side, on opposite ends, or whatever 
seems convenient, in a metal hobby box (or a plastic one, if you use the 
metal lid part).  Next, put a pair of almost any type of terminals 
(insulated from the box - this is where using that plastic box comes in 
handy...) somewhere convenient, and run a length of #22 solid wire from 
the centers of the two F jacks, one to each terminal.

Place VOM leads across the two terminals.  If using trusty Simpson 260, 
be careful of polarity.
