432 MHz preamp
Model:
MVV 432-VOX
Description:
Low-noise,
largesignal-firm 70-cm-mast preamplifier in weatherproof mast housing from ABS
plastic. The amplifier can be fixed by a clamp on masts with up to 56 mm in
diameter. All screws as well as the handle of the mast clamp consist of
stainless VA steel.
Within
the mast housing the amplifier is put in a shielded metal housing.
The
transmission receive switching starts from a transmitting power of 100mW input
automatically via HF-VOX, but can also be controlled by PTT as all our
preamplifiers. HF-VOX possesses an adjustable switch-off delay, which preserves
the relay contacts in SSB mode.
