Cell phone antennas, aiming from your fixed base station.Cell phone antennas are all different and each serves a definite purpose. This section will help you understand the difference of each type of antenna. The frequency at the bottom of the drawing is a typical cell phone service frequency. This example is a typical pattern of the capture ratio of this particular cell phone antenna. Because of the omni-beam 360 degree pattern of this antenna, this type of antenna is great at capturing the signal from the cell tower and relaying it to your mobile phone. The pattern your looking at here is typical of an antenna like mast type antennas other than a yagi or flat panel antenna.

The antenna radiation pattern below is better at capturing the signal from your cell phone tower in a moving vehicle even though it will work on let's say your rooftop on your home. Permanently mounting an omni-beam antenna on a building in a weak signal area will improve your cell phone reception, but a yagi is recommended if you want a stable signal suited for data transfer. A Yagi antenna focuses in capturing the cell phone signal from one direction, so these will need to be aimed carefully! Click the link at the bottom of this page to see where your cell phone towers are. You will need to know this in order to aim your wireless antennas correctly! On the next page you will see the capture ratio pattern of a yagi antenna. Once you go to the next page, it will be obvious why most in remote or fringe signal strength area will opt for a yagi! Yagi antennas are often used here in the Southwest connected to Data transmitters measuring bridge movent and hillside stability in mountanous regions. 
There are people living in remote locations around the country where they are either off the grid completely or just don't have access to phone or cable and these antenna systems are their only means of communication! There is a link below going to Off Grid Desert Living where this couple Authored an entire website from their home computer on a remote antenna system. That's how well these work when you set them up properly! Note in the pictures off the antenna they are using is a Yagi Cureved Panel hybrid. This setup is great for high speed internet connections! This setup they have is pictured in the section titled "Offgrid Solar and Wind"! Click here to go to Off Grid Desert Living! Click here to go to the wirelless antenna tower locating site.
