Further we offer:
Low-loss mast-mounted antenna switch for switching 2 or 4 antennas to one feedline, or for changing the polarization (horizontal/vertical) of X-quad antennas and crossed yagis. Low in-line attenuation, see table. 12 V DC operation (100mA max). For 2x switches one control wire is sufficient (use maybe an unused wire of the rotor control cable?) but the DC minus pole must be connected to the coax cable shield. Impedance 50 Ω, N connectors (female), supplied complete with mast clamp up to 54mm mast diameter.
The remote control connector on the AS-304 is a 4 pin DIN socket, a suitable plug is included with the switch.

The ACS-2004 allows connection of four antennas for all amateur bands from 80m to 70cm, switched to just one coaxial cable. Included is the control unit AC-2004 and the weatherproof outdoor unit AS-2004. Both devices communicate over one cable, also allowing to select independently 4 separate pre-amps.
Additionally the ACS-2004 switching systems contains a sequencer for controlling pre-amp and power amp keying.
If pre amps are to be used they are integrated between the antenna and the input of the switch.
To protect the switching contacts of the HF relays and the pre-amps, antenna selection is bloccked while the PTT is engaged.
Technical Data ACS-2004
Replace 5 coax feedlines with one! Ameritron's remote Coax Switch lets you remotely switch up to five separate antennas -- so you can replace five coax feedlines with a single coax. Eliminate a tangle of troublesome coax and have a simple and neat installation -- with just a single coax feedline. The RCS-8V consists of two units -- the weatherproof switching box that mounts on your tower or mast and the control unit that's placed at your operating station. VSWR is less than 1.2 from DC to 250 MHz and less than 0.1 dB loss at 150 MHz -- if you operate HF to VHF/UHF. This RCS-8V is for you. It handles 5 KW below 30 MHz and 1 KW at 150 MHz. You can ground unused positions or leave them open. The indoor control unit is all metal to prevent RFI and TVI. It also has LEDs to indicate the antenna you've selected. A Lexan scratch proof front panel has a markable surface for labeling your antennas. The RCS-8V operates from 120 VAC power source. Uses any 6 conductor control line (not supplied) and allows safe operation with 14 volts control voltage.
Specifications
Remote controlled antenna switch similiar to RCS-8VX (see above), but for 8 antennas, up to 100MHz. Requires four wire control cable.
