These low-noise and large-signal preamplifiers from SSB Electronic are simply looped into the coaxial cable. Power is supplied by remote feeding via the coax cable. Most modern transceivers have a built-in remote feed for mast preamplifiers, so in these cases no remote feed crossover is required. Otherwise, various remote feed crossovers with (DCW-15) and without (DCC-12) sequence control are available.
The amplifiers have a built-in HF-VOX, which ensures safe operation up to 100 watts. For higher transmit powers PTT control or the use of a sequence control (e.g. DCW-15) is required.
Out-of-band signals are effectively filtered out by built-in edge-partial helix filters. True coaxial relays are used for transmit-receive switching. Each individual amplifier is carefully calibrated at various measuring stations before delivery.
The amplifiers are installed in a double-shell, weatherproof housing: inside an HF-tight tinplate housing, outside a UV-resistant, seamless plastic housing with mast clamp.
The duoband models require only one connection each for the combination antenna and the down-conductor cable because of the diplexers already built in.
The MHP series includes mast preamplifiers for highest demands. The high gain is suitable for use with "weak signal" modes such as Tropo-DX or EME. The maximum allowable transmit power of 1500 W makes these preamplifiers very suitable for contest or EME operation.
The amplifiers are equipped with UV-resistant, weatherproof housings and N-type jacks. Hot-dip galvanized clamps and stainless steel mounting hardware are included.
