Network Antenna

It's a parabolic Scheffler solar cooker.

Xnec2c antenna simulation

Hypersensitive parabolic microphones, pointed in all directions.

He's fried his antenna.

Climb the tv antenna!

This is its antenna right there.

That was our HF radio antenna.

Looks like an antenna or... or...

Who was it helped fix my antenna?

Is there an antenna on the island?

We're tuning her antenna, as it were.

When you were controlling the feed, did you notice it was parabolic?

The man tried to install his own antenna.

People ask me how they make the antenna.

I invented a plasma antenna, to shift gears.

We've got a problem with the antenna ringing.

The TV antenna broke away in last night's storm.

You'll get a clear picture with this antenna on the roof.

That's the cable for the antenna so you can watch TV?

I was told that the loss of an antenna wasn't critical...

And that shark leaping there, if you look carefully, has an antenna.

It's a piece of plastic with a Radio Shack antenna attached to it.

It's just a hollow piece of plastic with an antenna that swivels around.

This down here, if the camera can see that, that is a small antenna.

But like any long length of charged wire, it also inadvertently became an antenna.

like a tuning fork the antenna resonates, and there's more energy coming out of the antenna than there is the backscatter from the ground that we're trying to analyze, taking too much processing.

I says, Why don't we make an antenna that only exists when you want it?

The town mayor made a narrow escape from the waves by clinging onto this antenna.

Say 40 minutes to crawl down there, an hour to patch in and align the antenna,

The wasps grabs onto one of the antenna, bites down on it, of the cockroach, and pulls the cockroach.

He opens the window of the attic, of course, and there's a tablecloth wrapped around the building's television antenna.

Thomas Watson spent hours listening to the strange crackles and hisses and chirps and whistles that his accidental antenna detected.

See, the closer I get to this antenna, the higher the note gets (Portamento) and you can get it really low.

Arno Penzias and Robert Wilson were using the horn antenna at Bell's Holmdel laboratory to study the Milky Way with extraordinary precision.

What happens is, by firing each one, they produce radio frequency energy that normally comes off of an antenna, spreads out rather rapidly.

like this petrochemical plant you can't use RF, it may generate antenna sparks, but you can use light you see plenty of light there.

Here's Burt Rutan and my good friend Greg Meronek inside a zero gravity people think a zero gravity room, there's a switch on there that turns it off but it's actually parabolic flight of an airplane.

The idea dates from 1960, when a young astronomer by the name of Frank Drake used this antenna in West Virginia, pointed it at a couple of nearby stars in the hopes of eavesdropping on E.T.

And what we've been able to do is engineer a virus to basically take dye absorbing molecules and line them up on the surface of the virus so it acts as an antenna, and you get an energy transfer across the virus.

It runs on solar, and it sends a signal with that antenna and bounces it off of micrometeorite trails in the atmosphere to a place in Bozeman, Montana, where the data is taken down and then sent through landlines to San Francisco, where we put the data in real time up on our website.

As we were talking to the vendor to try to learn about how you could apply these, or how they're being applied currently he was telling us that, in the military they use this one so soldiers can keep it on their chests very concealed and then, when they're out on the field, erect it as an antenna to clearly send signals back to the base.

Well, in order to not have to open up the person every time you want to reprogram their device or do some diagnostics on it, they made the thing be able to communicate wirelessly, and what this research team did is they reverse engineered the wireless protocol, and they built the device you see pictured here, with a little antenna, that could talk the protocol to the device, and thus control it.
