AW: LF: low noise OPAs and Transistors

[Stefan Schäfer <schaefer@hst.tu-darmstadt.de>]

Hi Alberto, 
 
Tnx for reply. Let us know about your loop preamp if it is finished. 
 
I already have ordered 10 pcs of the BF862 for my active E Field active 
antenna! This FET is MUCH more sensitive than the BF245C and has 1/10 of the 
noise of the J310...
 
73 es gl!

Thanks Stefan,

    very interesting if one has to build a low noise loop preamplifier (as I 
have...:-)
