Thanks, I see it on the board. But you mean short pins on J100, right?

The dbsrx board has a header on it designed specifically to do this.
Just provide the voltage on J100, a 2 pin header. If you have one of
the newer dbsrx boards, rev 2.1, just short the pins of J101, and you
will have 5V at the antenna port.
