I don't know about 4-400 but for sure I've seen the 3-500z in FM 88-108.
It was when in italy exploded the private radio phenomena, just during the
middle seventies.
I remember the dish with the larger pins was removed and the classical soket
not used, I don't know what it was the output circuit, the power anyway
decreased at upper band edge.
Honestly I wouldn't waste my time in building anything similar nowadays,
unless it is just for a didactical effort.
