Fig. 2: Layout of the Vee Beam. The two key parameters of a Vee Beam are the leg length the length of each wire, measured from the feed-point and the included angle that is, the angle that the two wires (legs) make to each other. A Vee Beam will perform well as a directional antenna with a leg length of between 1 and 5 wavelengths. Overall length: 737.9 feet This antenna would use over 2000 feet of wire, and here is how this monster antenna performs at a height of 200 feet above ground. From EZnec+ ver. 5.0 we have the following patterns: The overall efficiency is 47.2% This rhombic has 16.64-8.5 = 8.14 dBd gain.

Definition: V antenna is a type of long wire antenna whose structure is designed in the form of a V. This is the reason it is given the name V antenna. It operates in the high-frequency range between 3 to 30 MHz. Basically, it is said to be an enhanced version of a long wire antenna that provides higher gain and directivity than long wire antenna. What is a V-Beam Antenna? Stan Gibilisco 38.3K subscribers 5.3K views 8 years ago.more.more Think of this wire antenna as a half-rhombic.http://www.sciencewriter.net A 35 foot push up mast. Push up mast braced against a tree. Unfortunately, once everything was in the air, I was first only able to get 65 feet of wire into play for each leg of the antenna. Then the angles of the wires came out to 60 degrees and 100 degrees. This would put center aim at roughly 80 degrees, way off the mark for Europe. The layout of the antenna and a radiation pattern of an unterminated Vee Beam. If each end is connected to earth through a 600 ohm non inductive resistor, the antenna is called a terminated Vee Beam and the front to back ratio approaches about 3 S points. Even so, the gain is slightly less than the unterminated type.

A better version of long-wire antennas is the V-Antenna. This antenna is formed by arranging the long wire in a V-shaped pattern. The end wires are called as legs. This antenna is a bi-directional resonant antenna. Frequency Range The frequency range of operation of V-antenna is around 3 to 30 MHz. This antenna works in high frequency range. V-Beam is radar scan pattern modus in which separate radar transmitters feed two antennas which produce vertical fan beams . One antenna is tilted from the horizontal by approximately 30 degrees. This has the effect of displacing the resulting fan-shaped elevation beam by the same amount from the vertical. THE ANTENNA! It really turned my antenna farm upside down! And what a relief. My wife loves me again! It reduced the antenna farm from several Quads and 3 element junior beams for several bands into the latest one element design. A 6 band one element horizontal V-beam covering 20, 17, 15, 12, 10 and 6 meters! Big Antenna Rhombic, V beam antenna K0UO RHOMBIC ANTENNA FARM The Mighty Rhombic is the "KING of Wire Antennas". The ARRL, RSGB, Switzerland, and so many other amateur radio organizations use the Diamond Logo, which is in fact a Rhombic antenna.

Abstract: Conventional multi-beam forming with fixed-position antenna (FPA) arrays needs to trade-off between maximizing the beamforming gain over desired directions and minimizing the interference power over undesired directions. In this letter, we study the enhanced multi-beam forming with a linear movable-antenna (MA) array by exploiting the new degrees of freedom (DoFs) via antennas. Most people have seen the popular Yagi style antennas that use three, four, or five elements and take up large amount of real estate in the sky, but many people aren't familiar with smaller beam antennas such as the V-Quad. The V-Quad is an aluminum antenna that consists of a 6′ boom upon which two triangle shape elements are placed at either end.
Rhombic, V-Beam, and Other Broadband Antennas. Some antennas have very little impedance change with frequency. Log Periodic, Terminated Inverted V's, Terminated V-beam antennas, and Terminated Rhombic antennas are examples of antennas that have stable feedpoint impedances over very wide frequency ranges. Select a balun closest to the antenna. Broadband vee-beam offers a number of advantages over a typical flat-top multiband dipole or windom. First, continuous frequency coverage presents a low VSWR to your transceiver. This multiband wire dipole antennas does not require the use of an antenna tuner on one or more HF bands.

REF2 Horizontal V Antenna for 15 Meters. "The HORIZONTAL V ANTENNA FOR 15 METERS". This often leds to the question of what is a Beam Antenna. In it smallest of states, the Horizontal Vee, must be one of the least researched or understood antennas. After stumbling on misleading data one would think the antenna to be a dud, that efforts to make.
