Gain Antenna

Cellular Yagi Antenna explained

Explanation: Increase the frequency, distance cell phone signal, the frequency mobile, find your location of cell tower

The Yagi cell

One question The most common is around I get Yagi cellular antenna used in rural and remote areas to get a strong signal from cell phones, the extension of cell phone signal, and works with more cellular repeater systems for wireless building.

Like many things on the Internet becomes confused going from one place to another with each of them, apparently giving different information and claiming be the best. We took the time to explain, without trying to play an engineer.

This will allow you Yagi compare ' apples to apples. "

Yagi antenna: The most common cell phone directional Booster is known comes from the antenna Yagi yagi or a cell phone. Named after its inventor, who created it in 1908. Is the antenna of choice for most professionals cellular signals need high performance constant.

Yagi antennas are generally used as the outside, or "donor" antennas. Yagi cell phone use are usually a single band, which means they are designed and manufactured to work 800 MHz or 1900 MHz, but not both. Some ISPs claim to have two antennas yagi band, but the evidence for two major satellite manufacturers, we found that one of the two signals suffers. This due to the antenna for frequencies below require more area than the higher frequencies.

A Yagi antenna is made with a number of vertical bars or elements mounted on a long horizontal bar. A drawing of an antenna Yagi type is shown below:

Yagi antennas can not receive or transmit a signal through the side or back, the forehead.

dB vs. dBi: These are the words used to describe the amount of gain on an antenna provides the signal strength of the device used as a cell phone. dBi is always two largest numbers that dB. Therefore, an antenna 13 dBi gain antenna is the same 11 dB. The designation is simply by using the user's discretion. It is important to compare "apples to apples" when comparing prices.

Gain: Due to the nature of RF signals Yagi generate more of a gain of 13 dBi. the realization of additional revenue reached an early point of diminishing returns.

Example: A 800 MHz 13 dBi Yagi is typically about 32 inches long. Achieving an increase of 2 dBi of 15dBi, area (length) should be roughly doubled.

Therefore, care credits over 13 dBi Yagi antenna for use in the 800 MHz and 1900 MHz.

Applications: Yagi antennas are usually mounted on a pole and secondary overcome the obstacles that the line of sight. One reason they are so highly recommended is that the high gain allows them to be raised without causing a significant loss for the use of coaxial cable lengths often required in the assembly station antenna.

Example: LMR400 coaxial cable (Wilson 9913) has lost four tenths of a dB of three meters on 850 MHz while the length of fifty meters lose a total of 2 dB. 9 dB, which is available the connected device (cell phone, etc.) and the net gain of antenna gain of 11 dB.

The new increase is necessary yagi for many applications in rural and remote areas. Most systems use the repetition of cable for the signal to the amplifier much than possible.

Its frequency: To determine if you need 800 or 1900 MHz Yagi, go to UnwiredSignal.com and click on "Find your heart."

Your Torre Location: from the Yagi antenna should point to your tour of duty suppliers, it is necessary to know where he is. There are three ways to find the location of the cell tower. They are:

1. If the place where the use yagi is not blocked by trees or tall buildings around it, walk around the perimeter of building with his cell phone. Part of the building with the reading of the strongest signal is usually the address of your turn.

2. Call the service provider's customer service and ask. If I'm not going to give it to you, do not. Hang up and radio. What follows is likely to say they are happy to give the location of the tower you.

3. Mt antenna connects to your cell phone or a computer portable air port card external antenna, if equipped with one. Then turn the yagi at 10 degree increments until you have signal strongest. You'll need the adapter that adjusts the antenna cable to connect the mobile phone or air card.

Note You can not keep a Yagi antenna to try to fit in. in height Yagi antenna must be mounted on a metal pole where you want to use it permanently. You must completely remove the hand every time you turn the yagi and wait 5-10 seconds before requesting a change signal strength. Using the phone in test mode can help you find your cell phone tower location / address.

Phone Test Modes: many cell phones can be put on trial "Mode" field test for signal strength. This allows you to read the signal strength in decibels instead of bars. You can reach field trial one way of basic strokes.

NOTE: The signal strength is indicated by a negative number, but it will have a minus sign to come. Therefore, the higher the number, the stronger the signal. This indicates a strong signal of -75 to -85.

To find the menu Put the cell phone or PDA mode field trials will then click UnwiredSignal.com Support.

The signs of the distance: If mounted correctly, with the line of sight to the signal (not necessarily tower) looking for a high gain Yagi antenna to send and receive signals for miles.

You can expect even better performance when a high gain Yagi antenna, the gain is 13 dBi 301 111 Wilson used with a direct connection Wilson 3 Watt amplifier.

Example: Our customers are successfully using such applications in 1925-1930 miles offshore in the Gulf of Mexico and many other applications remotely.

antennas Yagi antenna is often the choice when you use a wireless repeater system 801 245 Wilson as Small Office Home Office system and the system of 801,106 Wilson wireless repeater for large and / or weakest signal outside applications.

type of coaxial cable required: type and length of coaxial cable to be used with any signal booster cell phone antenna, the map of air and / or amplifier depends on the frequency that the antenna works. The factors that determine the type and length of coaxial cable to be used:

1. RG8X coax should not be used in applications in 1900 MHz. Do not use in lengths of more than forty feet when using 800 MHz double shielded cable is considered low loss, but still lost 7.7 dB per hundred feet at 800 MHz

LMR400 coax must be used with all 1900 MHz applications, over wireless repeater (booster) systems and lengths of more than forty feet to 800MHz.
