Great for the out of the way home or Cabin where Cellular Reception was just a wish . Especially when used in Conjunction with a Cyfre or Signal Control Technology amplifier . You may be able to get cellular reception in places it was never possible before.
Please note All Yagi antennas are Directional and must be aimed at the nearest appropriate cellular tower for Optimum performance
How Do These Antennas Achieve So Much "Gain"? Basically they are directing a major or almost all of their signal in just one direction instead of dispersing all around a 360 degree circle. All those single element whips and rods on cars, boats etc are unidirectional, doing the 360 degree job. Zero (unity), 3, and 5db gain are the typical numbers for those. Usually the taller they are (for a given frequency) the more gain is laid out on the horizon, where it is needed.
What Is "Gain"? This is the common term used when measuring decibels (dB) to determine the effectiveness of an antenna in a given direction or plane. Simply put, it is the measure of the intensified signal where it is wanted or needed because antennas cannot create gain. The antenna is designed to manage the power in the wanted direction and thus reduce it in unwanted directions.
Where Can I Mount The Antenna? The available length of your feeder cable may determine your mounting spot and cable length considerations will address later. Otherwise any vertical or horizontal pipe, roof edge, wall, window sill, balcony railing or fence post can be used. Also, inside-attic hidden install is acceptable as long as there is no metal in the roof that signal has to penetrate. Wood and concrete are normally invisible to RF signals but at these frequencies (824-894mHz) gain may be reduced.
Where Do I Point The Antenna? The front of the antenna has to be directed at the target, the cell site or repeater tower or other user. It is best to use a map and compass and knowledge of target location but usually you can locate the target if it has a signal being sent to you. By simply rotating your Yagi until best signal is found then centering on the estimated location, satisfactory results may be had. Slowly rotate the antenna and stop every 10 degrees. Record signal levels. Note the peak and decline positions and soon a center can be figured out then tighten the mounting bolts. Be sure to stand at least a couple of feet away from the antenna and to the back or sides, never in front of the antenna. Your body can greatly alter signal patterns
