Review WESTERN ELECTRIC Signal Corps Antenna Relay

Product Description:

The BC-451-A Signal Corps Antenna Relay, manufactured by Western Electric, is a vintage piece of communications equipment that is highly sought after by collectors and hobbyists. This relay is designed to switch antenna circuits in a radio transmitter or receiver, allowing for multiple antennas to be used in various applications.

The BC-451-A is a single-pole double-throw (SPDT) relay, which means it has one common input and two separate output paths. It is a mechanical relay, meaning it uses physical contacts to make and break electrical connections. It is equipped with a coil that can be energized to change the position of the contacts, allowing for the switching of antenna circuits.

The relay is housed in a sturdy metal enclosure that measures approximately 2.5 inches long, 1.5 inches wide, and 1 inch high. The enclosure is made of heavy-duty steel and is painted a matte black finish, providing a durable and professional appearance. The relay has three terminals: one for the coil, one common input, and two separate output paths.

The BC-451-A is a valuable addition to any vintage communications collection or can be used in restoration or repair projects for older radio equipment. It is also popular with hobbyists who are interested in amateur radio or radio history. This relay is a testament to the high-quality engineering and craftsmanship of Western Electric, a company that was a leader in the telecommunications industry for over a century.

In summary, the BC-451-A Signal Corps Antenna Relay is a vintage communications relay that is equipped with a coil and can be used to switch antenna circuits in a radio transmitter or receiver. It is a single-pole double-throw relay that is housed in a heavy-duty steel enclosure and is a valuable addition to any vintage communications collection.

Details:

Except for the case deformation, unit shows very little wear. A schematic and parts list is available, as I have the operation maintenance book for complete radio set. The Weston meter is in excellent condition. The only function I can not verify is antenna current transformer and associated Thermopylae.

From a WW ii army air force scr-274-n radio set, this is the BC-442-a antenna relay unit. The antenna relay operates properly when energized with 24 CDC, switching between and rec terminals, grounding terminal is active. It was then connected in series with the antenna to effectively shorten. The missing high voltage vacuum capacitor, c69, was only required if aircraft antenna too long, thereby preventing transmitters from being properly coupled.
