Low-noise, largesignal-firm mast preamplifier in weatherproof mast housing from ABS
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 by 100mW input 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.
