SSB Electronic Mast-Mount Preamplifiers
SSB Electronic Mast-Mount Preamplifiers are low-noise, band-specific, weatherproof preamplifiers designed for installation near VHF and UHF antennas. Available for the 6 meter, 4 meter (Europe), 2 meter and 70 cm Amateur bands, these preamplifiers are installed in-line, at the antenna. They improve receive performance by amplifying weak signals before feedline loss can reduce them. Powering and Sequencing Most models can be powered remotely through the coaxial cable, and many modern transceivers include a built-in bias-tee for mast-mounted preamplifiers. If the transceiver or transverter system does not provide power, an external bias-tee or remote-feed unit is required. • The DCW-15 and DCW 2004B provide sequencing support. • The DCC-12 does not provide sequencing. • SP series preamplifiers include a built-in RF VOX circuit for safe operations up to 100 watts; for transmit power above 100 watts, PTT control with a sequencer is required, some required direct DC connection (UHF female). • -S series preamplifiers feature lower current signal relays with slightly higher insertion loss. • MHP and MHP-S series preamplifiers versions require sequencer control (see below). Signal Filtering and Switching Built-in helix filters effectively reject out-of-band signals, helping maintain clean receive performance. Real coaxial relays handle transmit/receive switching, resulting in very low insertion loss (except for SP-S series). And each amplifier is carefully calibrated at multiple test stations before packaging. Dual-Band Models Dual-band models include built-in diplexers, so they require only one connection for the multiband antenna and one connection for the station coaxial cable. MHP Series for Demanding Stations The MHP series is designed for demanding operating environments and provides higher gain for weak-signal modes such as Tropo-DX and EME. With maximum transmit power handling of 1500 watts on 6m and 2000 watts on 2m and 70cm, these preamplifiers are well suited for contesting, DX, and EME operation. Important Note for MHP Models Bias-tee power is not supported, as MHP Preamplifiers must be powered directly using the appropriate cable size for the required distance, and they may only be operated with a correctly wired sequencer, such as the DCW 2004 B Sequence Controller. Transmitting high power without a directly wired sequencer is likely to damage the MHP preamplifier. Housing and Hardware All SSB Electronic Mast-Mount Preamplifiers are supplied in UV-resistant, weatherproof housings with Type N female connectors. Hot-dip galvanized clamps and stainless steel mounting hardware are included. See individual models for band coverage and detailed specifications.

SSB Electronic LNA Series Low-Noise Preamplifiers
SSB Electronic LNA Series Low-Noise Preamplifiers are newly developed low-noise receiving amplifiers for the 6m, 2m and 70cm bands, featuring super low noise with high gain, making them ideal for use in EME (moon bounce), MS (meteor scatter), Aurora and tropo-DX operations. High performance is reflected in exceptional IP3 test figures (35dBm, typical), to provide strong signal immunity. Very good rejection of strong signals near and far guarantees interference-free operation, even in the vicinity of other radio transmissions from commercial and broadcast stations as well as mobile carriers. The input circuit of the amplifier is built with high quality components in a chamber construction, optimized for the best noise characteristics. The bandpass at the output of the amplifier ensures very good in-band selection with signals outside the pass band effectively suppressed. The LNA Series Preamplifiers do not have RX/TX relays and are intended for receiving applications. LNA Series Preamplifiers are built in a sturdy tinplate housing, suitable exclusively for indoor applications (Ip41 to DIN EN 60529). Choose between models that have two Type-N female connectors, Type-N Male and Female, and SMA female. These amplifiers can be powered via an external cable or via a coaxial bias tee (remote power supply). The -MA weatherproof variant of the receive-only LNA series is characterized by a robust, IP44-protected housing, allowing the high-quality preamplifier to be mast-mounted close to the antenna using Type-N connectors only. Power is supplied exclusively over the coax. If your receiver does not output 12-15 VDC receive preamplifier power onto the antenna feedline, use the SSB Electronic DCC-5000PRO Bias Tee (remote power inserter).

SSB Electronic LNA-30 Broadband 5 kHz – 30 MHz Low Noise Mast-Mount Preamplifiers
SSB Electronic LNA-30 Broadband 5 kHz – 30 MHz Low Noise Mast-Mount Preamplifiers cover the VLF, LF, and MF range, including the 2200 through 10 meter Amateur bands. Only for receiving applications, the LNA-30 is used to transform a simple wire or small whip antenna into a powerful broadband receiving antenna. This allows, for example, an SDR receiver to be operated in an unfavorable location with limited space and still deliver very good results. A skimmer or The LNA-30 amplifies the signals received by about 20 dB. The operating power can be varied for effect from 12 and 24V, with higher gain achieved at 24V, but the lowest figure at 12V. A very RF quiet, well filtered linear power supply should be used, not a switching power supply, which connects to this mast-mounted preamplifier via a separate coaxial cable; a UHF female handles the power input. The LNA-30 handles the RF separately with Type-N female connectors for antenna and receiver. When power is removed the preamplifier turns of and no signal from the antenna passes, making this an "always on" broadband preamplifier. The LNA-30 may be mounted on masts up to 2.25 in. (58mm), is weatherproof, and should be placed outside, close to the receive antenna. This preamplifier cannot pass RF power and is not suitable for transmitting operations.

SSB Electronic LNA-5000 50–5000 MHz Wide Band Mast-Mount Preamplifiers
SSB Electronic LNA-5000 50–5000 MHz Wide Band Mast-Mount Preamplifiers increase signal sensitivity for scanners, receivers, and measuring devices. They may also serve as a low-power amplifier or buffer amp. Built with a modern MMIC on a low-loss ceramic microwave substrate, it provides approximately 20 dB gain, a low 2 dB noise figure, excellent large-signal handling with IP3 greater than 30 dBm, and input IP values improved by 20 dB over the previous version. An input amplitude limiter helps protect against electrostatic discharge. The LNA-5000 supports up to 160 mW PEP / 20 dBm output, uses Type-N female connectors, covers 50 to 5000 MHz, and operates from a 10–20 VDC supply either directly through the DC Input UHF female connector or remotely through the RF coax using an optional DCC-5000PRO Bias Tee.

SSB Electronic DCW 2004 B Sequence Controllers
SSB Electronic DCW 2004 B Sequence Controllers provide properly timed power to remote mast-mount preamplifiers, as well as timed keying for RF amplifiers and transverters. Designed for convenient remote powering of SP and MHP series preamplifiers via the coaxial cable, the integrated sequential control reliably prevents sensitive preamplifiers from being damaged by RF peaks during switching operations. For the control of external devices, the DCW 2004 B provides three switching outputs with increasing delay times, so other components can be activated in a defined sequence. Features of the DCW 2004 B Sequence Controller: • Remote power (bias tee) via the coaxial cable for SP and MHP series Preamplifiers. • Delayed switching of RF linear amplifiers. • Three sequentially controlled switching outputs. • PTT input for switching to ground or +5 to +12 VDC. • Independent switching of preamplifier and power amplifier. • Low insertion loss of only 0.1 dB and high shielding effectiveness. • Automatic short-circuit test of the preamplifier feedline. • Last-State Function stores the previously selected operating mode. Please note: Extended Connections diagram must be used for proper keying delayed sequencing (see the diagram in the Documentation link). Advance keying is required for SSB mode with a footswitch, or for CW mode an external keyer with a PTT output, which must be connected to the sequencer (via pin 3 in and pin 1 Ground). With these initial Ground on Transmit PTT signals, each output is delayed by 200ms, 250ms and 300ms respectively: First, the sequencer removes bias tee coax DC power to the mast-mounted preamplifier; Second, it keys the amplifier (via pin 5 out); Third, it keys the transceiver (pin 6 out) or transverter. Fourth, the extra relay output on pin 7 for the transceiver if a transverter is used. Upon release of PTT input, all outputs release immediately, except for an additional 200ms delay before power is restored to the receive preamplifier. Due to timing delay of transmitter keying, CW mode keying of the transceiver cannot use VOX. Technical Specification of the DCW 2004 B: - Operating Power: 12 – 14 VDC, 2.1mm center positive - Band Coverage: 6 m, 4 m, 2 m, 1.25 m, 70 cm, 33 cm, 23 cm - Power Handling (Digital, CW & Phone): - 6 m / 1500 W - 2 m / 1500 W - 70 cm / 800 W - 23 cm / 400 W - Insertion Loss: 0.1 dB - Preamplifier Power (bias tee): 13.8 V max 500mA load - PTT switching output: 30 V at 500 mA max. - Relay switching outputs: 30 V at 500 mA max. - Ground On Transmit Voltage PTT Input Threshold: < +2 V - Positive Voltage PTT Input Threshold: > +5 V - Dimensions (WDH): 5.512 x 4.724 x 2.087 in.

SSB Electronic AS-3000A Mast Mount Antenna System Switch
SSB Electronic AS-3000A Mast Mount Antenna System Switch is an integral part of a low-loss preamplifier and power amplifier control for two-way VHF, UHF and SHF stations. Covering the entire range from DC to 3 GHz, two high quality SPDT coaxial relays, housed in their weather- and UV-resistant enclosure, provide excellent power handling and port isolation with minimal insertion loss. The solid aluminum chassis base incorporates a mounting bracket for a 1.5 to 2.4 in. mast clamp, with six downward facing Type-N female connectors for the antenna, a mast mounted preamp, a power amplifier and the station. A single Type-F connector provides DC out for the preamplifier and a 4-pin DIN with mating connector is used for direct DC control of the relays, typically with a sequencer. User supplied shielded control and power cables are recommended to prevent RF induced false keying. The AS-3000A supports the use of short lengths of coaxial cable for mast mounted equipment to dramatically reduce losses. Coaxial lines used in this type of system should be calculated and tailored so that they do not cause an impedance transformation. The connection of the transmitting equipment to the normally closed (NC) side of the AS-3000A relays allows the safe handling of high RF power without risk to the mast mounted preamp or LNA. Voltage is required to engage the normally open (NO) side of the relays for connection of the receive only preamplifier or LNA to the antenna. Removal of the voltage, or if power is lost, allows safe transmission without worry of equipment damage from transmitted RF, and keeps the preamplifier offline when the station is not used, for charge and pulse protection. See the linked documentation for detailed diagrams of system connections which typically require a sequencer, such as the SSB Electronic DCW2004B (ESB-1025), and an LNA, Mast Mount or separately enclosed.
