This simplified arrangement has several advantages, including a shorter ground distance between the ends. For example, a dipole antenna for the 80 meter band requires a ground length of about 140 feet (43 m) from end to end. An inverted vee with a 40-foot (12 m) apex elevation requires only 115 feet (35 m).
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 ...
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]
The other elements are parasitic radiators like those of a Yagi except consisting of inverted "Y"s. Like the Yagi, the Gizmotchy is a directional antenna with a forward gain of approximately 12 dBi and a front-to-back ratio of 28 dB. The unique design of the Gizmotchy allows both vertical or horizontal polarization, through the use of separate ...
Depending on the specific requirements, various antennas (i.e. Sloper, T2FD, Dipole) can be used for NVIS communication, with horizontal dipoles or inverted V dipoles at about 1 / 5 wavelength above ground giving the best results on transmit and at about 1 / 6 wavelength on receive, according to military sources and an extensive ...
21% of Americans have chronic pain. A new study found that diets rich in vegetables, fruits, grains, lean proteins, and dairy was linked to less chronic pain.
Yes, The Sound of Music was inspired by the lives of the real-life von Trapp family, which included patriarch Georg von Trapp, matriarch Maria von Trapp and their 10 children (seven of whom were ...
