The dipole elements are 15.55 metres (51.0 ft) and the impedance-matching symmetric feedline (ladder-line or twin-lead) can be either 300 Ω (8.84 metres or 29.0 feet) or 450 Ω (10.36 metres or 34.0 feet). [7]
Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.
SSMB connector This is a 50 Ohm connector which is a small version of the standard SMB connector. They provide excellent electrical performance in a micro miniature footprint. The snap-on mating interface allows quick installation and dense packaging.
The Lectron Vortex Plug is the heaviest of the NACS-to-CCS adapters we tested, but we preferred the confident click of its locking mechanism over the A2Z EV adapter.. Unfortunately, it doesn't ...
A hexbeam, or hexagonal-beam, is a type of a directional antenna for shortwave, most often used in amateur radio. The name comes from the hexagonal outer shape of the antenna. It may also sometimes be known as a W-antenna, referring to the shape of the driver. The design looks something like an upturned umbrella.
Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]
A recent study found that adding 111 minutes of daily walking could help you live 11 years longer. Here's experts want you to know about walking's benefits.
Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. [1] The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3]
