An inverted vee antenna is a type of antenna similar to a horizontal dipole, but with the two sides bent down towards the ground, typically creating a 120- or 90-degree angle between the dipole legs. It is typically used in areas of limited space as it can significantly reduce the ground foot print of the antenna without significantly impacting ...
Louis Varney (G5RV) invented this antenna in 1946. [4] It is very popular in the United States. [5] The antenna can be erected as horizontal dipole, as sloper, or an inverted-V antenna. With a transmatch, (antenna tuner) it can operate on all HF amateur radio bands (3.5–30 MHz). [5] [6]
Inverted-'V' antenna When the two arms of a dipole are individually straight, but bent towards each other in a 'V' shape, at an angle noticeably less than 180°, the dipole is called a 'V' antenna, and when the dipole arms' end closer to the ground than their center branch-point, the antenna is called an inverted-'V' . The inverted-'V' is ...
The G5RV antenna is a dipole antenna fed indirectly, through a carefully chosen length of 300 Ω or 450 Ω twin lead, which acts as an impedance matching network to connect (through a balun) to a standard 50 Ω coaxial transmission line. The sloper antenna is a slanted vertical dipole antenna attached to the top of a single tower. The element ...
The AN/UMQ-13(V) system or MARK IV-B, is a meteorological data station that is owned and operated by the United States Space Force. [1] [2] This system allows meteorologists from around the globe to analyze and forecast meteorological data from polar orbiting satellites belonging to, National Oceanic and Atmospheric Administration (NOAA), [3] Defense Meteorological Satellite Program (DMSP). [4]
A turnstile antenna, or crossed-dipole antenna, [1] is a radio antenna consisting of a set of two identical dipole antennas mounted at right angles to each other and fed in phase quadrature; the two currents applied to the dipoles are 90° out of phase. [2] [3] The name reflects the notion the antenna looks like a turnstile when mounted ...
APT images from weather satellites can be received with a right-hand circular polarized, 137 MHz antenna. Normally, there is no need to have the antenna follow the satellite and a fixed position antenna will provide good results. The two most frequently recommended antennas are the crossed dipole and the quadrifilar helix antenna (QHA or QFH).
NOAA's GOES-R Series of satellites is designed to improve the forecasts of weather, ocean, and environment by providing faster and more detailed data, real-time images of lightning, and advanced monitoring of solar activities and space weather. GOES-17 can collect three times more data at four times image resolution, and scan the planet five ...
