Arnold B. Bailey was granted the US patent 2,184,729 Antenna System on December 26, 1939, after filing in 1937 for a vertical antenna providing coaxial element sleeve structures.
German physicist Heinrich Hertz first demonstrated the existence of radio waves in 1887 using what we now know as a dipole antenna (with capacitative end-loading). On the other hand, Guglielmo Marconi empirically found that he could just ground the transmitter (or one side of a transmission line, if used) dispensing with one half of the antenna, thus realizing the vertical or monopole antenna.
The HB9XBG antenna is a vertical dipole antenna for short wave radio amateurs. It was developed by the Swiss radio amateur Walter Kägi, whose call sign HB9XBG is also the designation of the antenna. [1] During the test phase in 2020, HB9XBG built two vertical dipoles – one for the 20-metre amateur radio band and another for the 40-metre band.
Aug. 25—Whether the $700 million sale of Bazooka Candy Brands to a private equity firm will impact workers at a Scranton production plant is unclear. News outlets including The Wall Street ...
Southern Audio Services is an American electronics manufacturer based in Baton Rouge, Louisiana, chiefly recognized for its Bazooka Mobile Audio brand and product line. It focuses on mobile audio applications and accessories for cars and marine vehicles, and specializes in subwoofers mounted in a patented tube-styled design enclosure.
Bazooka is an American brand of bubble gum that was introduced in 1947. [1] It is a product of "Bazooka Candy Brands" (BCB), which was a division of The Topps Co. until the latter’s acquisition by Fanatics, Inc. in 2022.
A stereo dipole is a sound source in an Ambiophonic system, made by two closely spaced loudspeakers that ideally span 10 to 30 degrees. Thanks to the cross-talk cancellation method, a stereo dipole can render an acoustic stereo image nearly 180 degrees wide (single stereo dipole) or 360 degrees (dual or double stereo dipole).
The experimental Morgenstern German AI VHF-band radar antenna of 1943–44 used a "double-Yagi" structure from its 90° angled pairs of Yagi antennas formed from six discrete dipole elements, making it possible to fit the array within a conical, rubber-covered plywood radome on an aircraft's nose, with the extreme tips of the Morgenstern's ...
