'Electrical efficiency' is the ratio of power actually radiated to the power put into the antenna terminals.

First, because loud speakers actually radiate in all directions, some energy at low frequencies is radiated downwards.

In the fluorescent lights, Langdon was surprised to see that her strong air actually radiated from unexpectedly soft features.

Even the biggest ships, unless actually radiating brightness, would be impossible to spot, without the help of instruments, at any distance beyond a few kilometers.

So - even though its surface temperature had dropped - the Sun was actually radiating more energy, overall, than it had done before its swelling.

Studies have shown that this is probably a conservative precaution, particularly when the percentage of time an antenna is actually radiating is considered.

The man's actually radiating magik.

It flickered through the spectrum, settling on a dull red that felt as though it were actually radiating heat.

"Efficiency" is the ratio of power actually radiated by an antenna to the electrical power it receives from a transmitter.

He posits that the vertical sides of each element actually radiate the low angle component.
