Hi Edgar,

Bozidar has already identified the input Z (200 Ohms). As for the
rest of it, the schematic reveals it has a turret tuner (or barrel
tuner) for changing bands. Such a mechanism allows for tuning over
multiple bands to provide for both greater tuning resolution, and
linearity. The Tuning mechanism contains an antenna coupling filter
(following a general low pass filter with neon tube suppressor at the
input connector); two stages of Tuned RF amplification; and one Tuned
Mixer/Oscillator. The schematic is pretty rough, so I could be wrong
and it is one RF Amp, a Mixer, and an Oscillator. It may need
alignment for best service.

Almost any antenna longer than a whip (small wire dipole 10 - 20 feet
high) will do.
