Description:
Low-noise,
largesignal-firm 2m mast preamplifier. The weatherproof ABS plastic housing can
be fixed with a clamp to 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 low
noise factor is achieved by the use of a low-noise dual gate MES FETs, which
has a good large signal.
The
transmit-receive switching starts from a transmitting power of 100mW
automatically via HF-VOX, but can also be controlled via PTT as all our
preamplifiers. HF-VOX possesses an adjustable switch-off delay, which preserves
the relay contacts in SSB mode.
