  1. 1. Choosing the right cell phone antenna can make a substantial difference in your cellphone's signal reception. In fact, some antennas can provide up to a 13 dBi gain. Understanding how the antenna will connect to your phone, the difference between directional and omni-directional antennas, and how to choose one that works with your service provider will make all the difference when purchasing a cell phone antenna.diploe antenna
  2. 2. 1) How the external antenna will connect to your phone: Manyphones have an external antenna port on the back that can eitherplug into a car kit with an external antenna connection or can beused with an external antenna adapter When these options areavailable, any external antenna tuned to the frequencies the phoneuses are an option (limited only by where the antenna will be used asdiscussed below) The current trend with cell phone manufacturersis to not add the external antenna port as they are moving away fromcar kits due to Bluetooth technology
  3. 3. When the phone does not have an external antenna port, the onlyoption is a wireless amplified repeater kit Over the past diploeantenna few years there have been a number of products advertisedas working on phones without an external antenna port One of themost recent examples was a signal boosting sticker you attach to theback of the phone
  4. 4. Regrettably, none of these products have proven to provide anysignal benefit at all As a result, there is not an inexpensive way onthe market at the moment to increase signal strength in these cellphones 2) Omni-directional and directional antennas:Omni-directional antennas pick up the signal in a full 360 degreeradius, and so should be installed in a vertical position in the area ofstrongest signal
  5. 5. Directional antennas, however, pick up the signal in only onedirection This type of antenna is designed for use on stationaryobjects such as buildings It should be mounted above tree lines andpointed directly toward the nearest cell tower
  6. 6. The main benefit of a directional antenna is its ability to focus itssignal in one direction If the antenna is not aimed correctly it willlose its effectiveness 3) Choosing an antenna that works with yourservice provider: When purchasing a new antenna, be sure it iscompatible with your provider's phone frequency
  7. 7. For instance, while the same model of phone may be offered byVerizon and AT&T, and therefore the same antenna provided,each service provider has its own frequency Even though theVerizon antenna may fit in the AT&T phone (and vice versa), itwill not provide any signal due to its tuning to a different set offrequencies Almost all service providers use frequenciescompatible with Dual Band/Tri-Mode antennas; the exception isNextel
  8. 8. Dual-band antennas work with two frequencies, and while one of thefrequencies usually supports Nextel phones, it is best to purchase anantenna that is made to support just Nextel phones This will assuremore consistent, quality signal reception
  9. 9. Knowing how the antenna will connect to your phone, the differencebetween omni-directional and directional antennas, and how tochoose one that works with your service provider is essential whenpurchasing an external antenna Having the right antenna can resultin a gain of up to13 dBi
  10. 10. Understanding how antennas work will allow you to purchase thecorrect antenna and therefore optimize your phone's ability toreceive signals
