Double Bazooka NVIS Antenna Calculator The measurements below are for building a Double Bazooka Near Vertical Incident Skywave (NVIS) Antenna. com THE DOUBLE BAZOOKA ANTENNA Notes on Assembly of the Double Bazooka About The Double Bazooka Antenna The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. 75m resonant loop is poor performer for 40m. K4BBN Rating: 2017-01-25 My Bazooka Bullet Points Time Owned: 6 to 12 months. . It will provide excellent short range communications and is easy to set up for emergency or temporary communications. NVIS Antenna Rules Excellent antenna is a resonant 1⁄2 λ horizontal dipole at 0. Generally antennas that are installed physically high up tend to have more of their radiated energy leaving the antenna at a lower The NVIS antenna described is based on the proven information from the military AS-2259/GR antenna. Finch, AIØW Introduction The antenna axiom, “the higher, the better,” is true for working distant stations. 5 Mhz 3. Do not break the center conductor. Government. Home-Brew DOUBLE BAZOOKA rarely survive harsh elements and The measurements below are for building a Double Bazooka Near Vertical Incident Skywave (NVIS) Antenna. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends. See full list on practicalantennas. 300 Ohm Twin Lead with the ends shorted is an option for even greater bandwidth. DOUBLE BAZOOKA antenna is an extremely broad banded Half Wave Antenna which can operate efficiently across an entire Ham band (3. 25λ Inverted-V is some 2-3 dB worst than dipole, but has more uniform horizontal pattern. The larger the wire, the wider the bandwidth. A DOUBLE BAZOOKA antenna is an extremely broad banded Half Wave Antenna which can operate efficiently across an entire Ham band with little change to the SWR. Good performance from 0. Its bandwidth claims have sometimes been exaggerated. One antenna uses all coax the other uses coax and twin leadRead More The measurements below are for building a Double Bazooka Near Vertical Incident Skywave (NVIS) Antenna.

I am glad that I started my Ham experience with an antenna from the fine folks at International Antenna Corporation! Before getting licensed as a General just a few months ago, I spent several months listening to the HF bands through various Websdr sites and later, my own computer-based SDR unit. On this page I give details of how to build two different versions of the Double Bazooka Antenna. 1 day ago · Explore a variety of Bazooka antenna projects for amateur radio operators. S. 1λ to 0. Sep 24, 2011 · NVIS Antennas: Page 1 Background The material in this article is derived from The ARRL Antenna Book, 1957, 1974, and 1999 editions; Army Field Manual 24-18 and others, several QST articles, and various web articles written by other NVIS experimenters and HF antenna and propagation experts such as W4RNL. It was during The Near Vertical Incident Skywave (NVIS) antenna is a half-wave dipole antenna mounted not over 1/8th wave above ground (at the highest operating frequency). Build your own dipole or vertical Bazooka antenna with detailed plans and calculators. Dipole Double Bazooka NVIS Extended Double Zepp NVIS Use one of the above three Antenna calculators to determine the antenna length and which antenna best fits at your location. While 1/8th wave works reasonably well, better coverage is obtained if the antenna is mounted at about 1/20th wavelength above ground.
