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 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 models require a 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 (on the RF coax) is not supported in most MHP Preamplifiers. They 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 AS-3000 Two-Port Wideband Mast Mount Antenna Switch
SSB Electronic AS-3000 Two-Port Wideband Mast Mount Antenna Switch covers the entire range from DC to 3 GHz, featuring a low-loss SPDT coaxial relay. This model (ESB-5059) can switch two antennas to one feedline, or it can be used to switch between horizontal and vertical polarization on a cross-polarized Yagi or X-quad. Featuring high power handling, very low in-line attenuation and SWR, and simple 13.8 VDC operation, the AS-3000 is an excellent addition to any VHF, UHF or SHF station. The solid aluminum chassis incorporates a mounting bracket for a 1.5 to 2.3 in. mast clamp, with three downward facing Type-N female connectors, for the default normally closed (NC) port, a normally open (NO) port and the common port. A 4-pin DIN with mating connector is used for direct DC control of the relay, and a user supplied shielded control cable is recommended to prevent RF induced false keying. The AS-3000 supports the use of short lengths of coaxial cable for mast mounted equipment to dramatically reduce losses. Coaxial lines used with this switch and antennas should be calculated and tailored so that they do not cause an impedance transformation. Specifications of the AS-3000 Mast Mount Antenna System Switch (ESB-5059): Frequency range: DC – 3000 MHz Switch positions: 2 Insertion loss, typ.: 0.01 dB / 150 MHz 0.02 dB / 500 MHz 0.025 dB / 1000 MHz 0.03 dB / 2000 MHz < 0.1 dB / 3000 MHz Isolation: >60 dB / 2,5 GHz VSWR: <1.2 : 1 RF Power Handling, by band: 1000 W/2m; 800 W/70cm; 500 W/23cm; 250 W/13cm RF Connectors: Type-N female Direct DC Control Input: 4-pin DIN (mating connector provided) Switching Voltage: 13.8 VDC @ 250mA, max.
