Low-noise, largesignal-firm 4m-mast preamplifier, in weatherproof mast housing from ABS plastic.
The amplifier can be fixed with 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.
The transmit-receive-switching starts at a transmitting power from 100mW automatically via the inserted HF-VOX, or PTT-controlled as all our preamplifiers.
HF-VOX possesses an adjustable switch-off delay, which preserves the relais contacts in SSB mode.
