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.
