At shortwave frequencies, a dipole cut for the longest used wavelength, fed with ladder line and matched with an antenna tuner, would make better use of the applied power than the T²FD. [7] Many ready-made commercial versions of the T²FD are available for the professional, military, amateur radio, and hobby listening markets. [6] [7] [8]
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 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 ...
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 visibly less than 180°, the dipole is called a 'V' antenna, and when the dipole's far ends are staked closer to the ground than the center, it is called an inverted-'V' antenna. The inverted-'V' is popular since ...
An amateur radio station incorporating two HF transceivers. A typical Yagi antenna used by a Canadian radio amateur for long distance communication Boeing 707 used a HF antenna mounted on top of the tail fin [7] The main uses of the high frequency spectrum are: Military and governmental communication systems; Aviation air-to-ground communications
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 ...
