50 MHz preamp

Model: MVV 50 VOX

Description: 

Low-noise, largesignal-firm 6m-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.
