He sent me a working prototype which I replicated with the same good result . 

Due to the little dimensions a adapter for the fet is recomended even if it is not necessary if you have good eyes and steady hands. 

The adapter is made of a little piece of single side copper fiberglass or teflon board, on were are cutted four  "islands" were to solder the fet. 

I built my prototypes into a commercial 50x50x30 mm box, the position of  C2 and L1 is not critical, only the two compartments must be RF sealed, you can solder a finger stock on the divisory wall. 

I completely closed the output side with a square of 5mm thick conductive foam used for cmos protection, this solved some self-oscillation problems I found on the 432 Mhz one. 

The results should be abt 20 db gain and 0.3 - 0.5 db NF with a drain current abt. 10-15 mA.
