I have a DBSRX Rev 2.1, and I must use an active antenna that work at
(max 30mA of power consumption). First of all, I try to short J101 and I
have 5V without any load, when I try to use this antenna the output
go down at 35mV. I decide to test the voltage output where the load is
by same resistors and I measure 4.1V with a resistor of 100KOhm, 4.0V
50KOhm, 0.3V with 10KOhm. I repeat all measure with an external bias
via J100 and I find the gsame values.
How can I solve the problem?
