How many flux towers are enough? How tall is a tower tall enough? How elaborate a scaling is scaling enough?Ke Xu
000 hertz is about 361 feet (110 meters). So, AM radio stations need very tall towers. For a cell phone working at 900,000,000 (900 MHz), on the other hand, the optimum antenna size is about 3 inches or
Radio transmitters also use extremely tall antenna towers to transmit their signals. The idea behind an antenna in a radio transmitter is to launch the radio waves into space. In a receiver, the idea is to pick up as much of the transmitter's power as possible and supply it to the tuner...

High-voltage transmission lines are quite obvious when you see them. They are huge steel towers strung out in a line that stretches toward the horizon. All high-voltage towers have three wires for the three phases. Many towers also have extra wires running along the tops of the towers. ...
The bottom line is that outdoors and higher is better than indoors and lower. You know how radio towers tend to be very tall and out in the open? Same principle. Amplify, or not Antennas need amplifiers to ensure proper signal strength. Generally speaking, the longer the cable-run distance...
"Making this record was one of the most life-affirming experiences I've had, but it's calledThe Human Fear— fear reminds you that you're alive," shared frontman Alex Kapranos. "We all are addicted in some way to the buzz [fear] can give us. How we respond to it s...
Mass timber can be used as both horizontal and vertical structural components. Cross-laminated timber (CLT) is perhaps the most flexible type, and panels of it can perform many roles in structural systems. Because mass timber pieces are fabricated offsite, the material is well-suited to prefab...
Most of the rest time is spent sleeping. New Guinea singing dogs are famous for their howl (长嚎), which sounds like the song of a whale. In a group, one dog starts singing and the others all join in. They are 30 cm to 46 cm tall and can be up to 14 kilos. They live in ...
