Arie,
First, I should not have said you ignored Vsat. I got confused. Anyhow,
using standard tables, the Pi network values for a 2100 Ohm to 50 Ohm
network at 160 meters a

C plate = 427 PF
C load = 2213 PF
L = 18.4 uH

These are rather huge capacitor values, and might explain why the only two
amps that I saw schematics for, that covered 160 m, used either a Pi-L, or
some kind of transformer coupled output.
