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. Specifications of the AS-3000A Mast Mount Antenna System Switch (ESB-5058): Frequency range: DC – 3000 MHz Switch positions: 2 Insertion loss per relay, 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 LNA DC Connection: Type-F female Direct DC Control Input: 4-pin DIN (mating connector provided) Switching Voltage: 13.8 VDC @ 650mA , max.

SSB Electronic AS-304 Four Port Mast Mount Antenna Switch
SSB Electronic AS-304 Four Port Mast Mount Antenna Switch can be used on all frequencies up to 600 MHz and is electrically operated using a control cable and an optional control console. The weatherproof housing allows the mast-mounted switch to be installed as close to the antennas as possible with the connectors facing downward to keep connections dry. Equipped with heavy duty relays, the AS-304 is recommended for a variety of tasks due to its wide frequency coverage, low insertion loss and high power capability. Ratings are dependent upon the selected connector version, UHF or Type-N, as detailed below. The control of the AS-304 provides a no-voltage default selection of Antenna 1, with 13.8 VDC applied to one of three pins of the chassis 4-pin DIN connector to select Antennas 2, 3 and 4, with the fourth pin ground. The mating connector is supplied for the user supplied four conductor control cable. This type of 1-of-3 antenna port selection is handled with the optional DXE-CC-4 Four Position Control Console featuring a large rotary switch and 4 indicator LEDs, or with another third-party control device, or a user supplied rotary switch.

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.
