Element Yagi
is difficult for me to get these materials are very expensive ….. I am aware that the use of different materials in my performance, but I want to know what give high bandwidth that should cover almost the entire 70 cm band. The reflector and directors may be the cane. I like to ride a wooden dowel, broomstick. Leave

High Quality Content by WIKIPEDIA articles! A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system consisting of an array of a dipole and additional closely coupled parasitic elements (usually a reflector and one or more directors). The dipole in the array is driven, and another element, typically 5% longer, effectively operates as a reflector. Other p…

How do they work cell phone repeaters? To incoming phone signals, cell frequencies are? are the radio frequency levels. The FCC controls the airwaves in the United States and approves the various frequency levels for each provider service, or company. Generally, from 800 MHz to 894 MHz and 1850 MHz to 1990 MHz are reserved for Canada, North America and South America. The 800 MHz band building? RF signals at the cellular level simply can not penetrate solid building materials denser than, for example, drywall. They are close enough to the cell tower and situated so the signals pass through uncovered windows tinted.

If you have a good signal outside, the least costly If your cell phone has an external port, your solution will probably be a signal booster cell phone / different digital code reading technologies for mobile phones and air cards computer / data cards. See below:

CDMA: speeds up to 384 Kbps standard is based on GSM and CDMA use.

EV-DO: Evolution, Data Optimized (EV-DO) is a data connection high-speed wireless technology in the CDMA network. This technology allows users to access high-speed Internet via portable devices up (MMS), and for Internet communication services such as email and the World Wide Web access.

GSM: High Speed Downlink UMTS providers can lower this rate to cover the fees that the typical maximum 3.6 Mbit / s HSDPA support most of phones. Voice calls are usually priority think Sprint PCS is a product, they were, in fact, only one of the first companies in the United States to use it.

UMTS: up to 384 kbit / s for R99 devices and 7.2 Mbit / s for HSDPA devices in the downlink connection.

Is there a "passive repeater phone? No, (Just look at the size of the cables in one), such as radio and television towers. If power was not needed to boost signals, your provider services would only need a tower to serve That depends on several things: the current strength of the signal outside the place where you are the antenna outside the telephone repeater will be used and how often they want to promote.

My next-door neighbor can use your cell phone at home, why I can not? For the same reason you can talk on the phone she may have a different service provider Usually, between 50% -75% to the height of the trees that have thin enough so you can find a sweet spot. Then connect the Yagi directly or Wilson and his son is the only brand we carry. Legal and approved by the FCC.

Yagi vs Will an omni-directional antenna for repeaters phones? Yagi antennas have approximately twice the gain directional antennas, omni cell phone. In addition, all of the Yagi antenna gain in multiple four main suppliers, requires some knowledge and experience to design the system, but just as EZ to install as the others.

Female Antenna
Opaline gourami antenna problem?

My female opaline gourami had its antenna under its body maybe bitten off and so now its a small stub, I heard they grow back, but will it grow back even if its a stubb, or will it stay a stub? Are they like human hair and nails in that sense?
Could it get infected?

If a gourami can indeed grow back their antenna then a stub would grow back too. Treat the water with aquarium salt to help aid in the healing process.

Antenna Magnetic

February 22nd, 2010 admin No comments

Antenna Magnetic
What is the maximum emf induced in the antenna?

A loop antenna, such as is used on a television to pick up UHF broadcasts, is 25 cm in diameter. The plane of the loop is perpendicular to the oscillating magnetic field of a 150 MHz electromagnetic wave. The magnetic field through the loop is B = ( 20 nT ) sin(w * t).

Does that “” mean “divided by”? I hope not, or things get pretty wild twice per cycle. Assuming a peak value of B = 20 nT, area = 2pi*r^2 = 4.8097E-2 m^2 and angular rate w = 2pi*f = 9.4248E8 rad/s, the peak induced voltage V = N*d(BA)/dt = NBAw = 0.92528 V. (From Faraday’s law, see ref.)

A Look Inside Your Antenna

It’s probably not something many people are interested in unless they’re some kind of an electrical engineer or just bored, but understanding how an antenna works can be useful when the one on your TV or radio goes south on you and the reason is beyond your comprehension.  

Trying to explain how an antenna works in simple English is not an easy task as there are a lot of technical specifications that need to be explained.  But a general understanding is possible without getting into tech speak that would make Einstein cringe.  

In order for an antenna to work it has to radiate.  Your antenna, whether TV or radio has what is called free electrons running through it.  It is these free electrons that vibrate.  The question becomes, how do these free electrons vibrate and what causes them to vibrate?

Well, in real life it takes an electric field to move an electron.  If you take an isolated straight dipole, the power comes from the combined fields of all the charged particles, both positive and negative, in the antenna.  We’ll call this field the antenna’s coulomb field.  

In addition to this field, the antenna exhibits a magnetic field that is the sum of the magnetic fields of all the free moving electrons.  The antenna also has a dynamic electric field that is the vector sum of the dynamic electric fields of all the free electrons.  What we can do is separate the electric field of the antenna at any point in space into two components.  One of the components will be in phase with the total magnetic field and the other will be 90 degrees out of phase.  The in-phase component is the radiation field of the antenna and the out of phase component is the induction field.  At the antenna, both fields are parallel to the metal surface.  

What happens is that the coulomb field and the induction field fall off much more quickly than the radiation field as the distance increases from the antenna.  When you reach distances greater than a few wavelengths from the antenna, you have what is called the antenna’s far field.  This field is pure radiation.  As you get closer to the antenna you have what is called the antenna’s near field.  This field is a mixture of radiation, coulomb, and induction fields.  Still with us?  Great, we’re getting to the good part.  

What ultimately happens with all these fields that makes it so that your TV or radio picks up signals through your antenna is this.  The free electrons moving through your antenna are moving at their maximum speed.  The right hand half of your antenna accumulates electrons.  The left hand half of your antenna is where the electrons depart and leave an excess of charged ions.  The coulomb field produces an imbalance and opposes the electrons’ rightward motion.  The electrons then stop, coast for a bit and then head back towards the left.  After they reach maximum speed they then stop and process is repeated, now heading back to the right.  The result is a vibration of free electrons that heats the metal and in turn generates electromagnetic waves.  

And that, in as simple English as possible, is how your antenna works.
