When is a Yagi Antenna Warrented against Omni-Directional Antenna
One question we often get from new customers is what is a Yagi antenna and if they must get a Yagi antenna for better performance?
Yagi antenna is an antenna designed in a pyramid like structure with multiple elements with increasing length, usually 5% increments that act as reflectors, due to its intelligent design concentrates its signal capture capacity, simply put.
Both the above are Yagi’s ith some minor design changes. Now, to answer the question of when is a yagi preferred over Omni-directional antenna, which receives and radiates signals in a circular pattern parallel to earths surface.
The ultimate deciding factor in determining the type of antenna boils down to the tower location and how many towers is your cell phone using inside the building. Usually most of the major cell phone carriers share a common tower in which case a yagi would work the best, being a direction sensitive antenna that picks up signal in the direction its being aimed at. Wear as the omni directional antenna looks for signal in all directions it can pick signal from multiple towers in multiple locations regardless.
The trade off of using Omni-direction cell phone booster Vs Yagi cell phone booster is mainly in the signal sensitivity . Even though the Omni-directional antenna seems more bang for the buck in picking up signal from all directions, the sensitivity of a Yagi is marginally better then the omni-directional and proves very useful in situations where the signal strength is very weak. The rule of thumb is to go for an Yagi antenna when the outside signal is particularly very week and if the signal has to be picked from one tower.
