 Yes, given a low Z source - no good for E-field rx.


On the input of the E-field antenna i use a JFET (BF862), then a narrow
band pass filter and after that the LT1028. As the output stage i use again
the BF862, driving a fiber optical TX LED. Then, the RX signal is
transmitted by a fiber optic cable into the shack. Back-converting with
a SFH350V photo transistor...
