Antenna

The first telescopic observation of Mars was by Galileo Galilei in 1610.

One popular design of mobile phone antenna is the sector antenna, whose coverage is 120 degrees horizontally and about 5 degrees from the vertical.

The antenna was of the North American VertexRSI design.

The higher frequency Ku band systems tend to resemble DBS systems and can use a smaller dish antenna because of the higher power transmissions and greater antenna gain.

I looked at the coffee cup. A bit of antenna was still stuck to it.

When you run very short wavelengths, 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.

Users of the service connect to the balloon network using a special Internet antenna attached to their building.

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

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

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

The narrow beam width of a normal parabolic satellite antenna means it can only receive signals from a single satellite at a time.

Willis Tower (formerly Sears Tower) was the highest in the final category the greatest height to top of antenna of any building in the world at .

Kongsberg Satellite Services (KSAT) operates satellite stations at Svalbard, Tromsø and Grimstad, and is now in the process of installing an antenna at Troll in Antarctica.

Intrinsically safe environments 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.

And then, he had better telescopic, more fine grain data in which he could figure out that as the Earth is going around faster according to Kepler's Laws than Saturn, then we catch up with it.

Although the idea that the planets orbited the Sun had been suggested many times, it was not until the 17th century that this view was supported by evidence from the first telescopic astronomical observations, performed by Galileo Galilei.

Because base stations operate at less than 100 watts, the radiation at ground level is much weaker than a cell phone due to the power relationship appropriate for that design of antenna.

(c) Developing the means of communication and of computer science, including new mobile paid radio telephones and electronic cards for them, large ground based antenna systems for communications and television broadcasting and river navigation systems

However, they are not compatible with broadband broadcasts (which are received over an antenna), though some newer sets come with baseband NTSC 3.58 support (NTSC 3.58 being the frequency for color modulation in NTSC 3.58 MHz).

The sniper rifle itself could be based on a standard rifle (It's hard to define a sniper rifle by the fire modes as some latest designed sniper rifles are semi automatic fire, for example the M110) however, when fitted with a telescopic sight, it becomes a sniper rifle.

It may come over the air as with a radio station or television station to an antenna and radio receiver, or may come through cable television or cable radio (or wireless cable ) via the station or directly from a network.

Sapphire rises 54 floors above ground level, and boasts an above ground roof height of 238 meters the building has an overall structural height of 261 meters including its spire, which is part of the design and not a radio antenna.

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.

ZK 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.
