If you do not have a correct path to ground, your antenna will most likely be an attractant to lightning! As the wind blows, airborne dust particles collide with your metal antenna and mast. these collisions build up a static charge. this static charge does two things. How do youRead More →
Fetch is delivered by broadband, so as part of setting up you need to connect your Fetch Box to your modem. You can use Wi-Fi to connect if you have reliable Wi-Fi in the room with your TV and Fetch Box. You’ll need a Fetch Mini or Mighty (3rd GenerationRead More →
Most UHF antennas will actually do a decent job of FM reception as well. UHF antennas don’t pick up the FM band by design, but they don’t block it either. It’s just that FM radio doesn’t require a very complex antenna for reception. … In general, most antennas you’ll findRead More →
Thus, a plane mirror seems to be the best reflector of light. The correct option would be: D. Plane mirror. Which waves use parabolic dish? The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct theRead More →
The vertical dipole—or its electromagnetic equivalent, the monopole—could be considered one of the best antennas for LMR applications. It is omnidirectional (in azimuth) and, if it is a half-wavelength long, has a gain of 1.64 (or G = 2.15 dBi) in the horizontal plane. What is the impedance of monopoleRead More →
For example, AMEC states in its CAMINO-108 manual, “… the VHF antenna should be placed as high as possible and at least 5 meters away from any constructions made of conductive materials.” Vesper recommends, “Mount the antenna as high as possible (at least 2-3 meters (6-10 ft) above the waterRead More →
EMT (thin wall conduit) works just fine for small antennas. One inch or one and a quarter inch works well and is stiff enough for a small TV antenna, a discone, or a small vertical. What is a mast structure? A mast is a ground-based or rooftop structure that supportsRead More →
