Omni antennas can pick up cellular signals from any direction, but Yagi antennas usually need to be pointed directly at a cellular tower for the best performance. The directional or Yagi antenna (named after Japanese engineer Hidetsugu Yagi) is a highly directional radio antenna made to receive cellular signal from one specific direction. The omnidirectional (omni) antenna receives signal from a 360-degree field, meaning it can pick up radio-frequency (RF) waves from all directions. There are two types of donor antennas to choose from: omnidirectional and directional - also called "Yagi". Types of donor antennas (exterior antennas).ĭonor antennas are the outdoor antennas which pull in the existing signal to be amplified inside a building. This helps the installer assess the building's design, layout, and location in order to determine where the strongest signal is coming from, and where to place the donor antenna. The first step in setting up an outdoor antenna, more accurately called a donor antenna, is to complete a cell signal survey. Perform a site signal survey first for installing exterior antennas. They can be installed on ceilings if cellular boost is needed across multiple floors. Panel antennas radiate signal in one direction so they are ideal for wall installation pointing to the longest spaces along corridors and long spaces. They must be used for single level/floor reception boosting purposes. Types of interior signal booster antennas.ĭome antennas radiate signal in all directions so they are ideal for ceiling installation in center of large square or circular spaces. Depending on the need, multiple antennas may be required. Both types of antennas connect to the amplifier unit via coaxial cable. Broadcast antennas, or "inside" antennas, are installed on the interior wall (panel antennas) or ceiling (dome antennas) and transmit the amplified signal to phones and other cellular devices indoors. Donor antennas are installed on the roof or near a window and bring the outdoor signal in. Types of signal booster antennas.Īntennas are a key component of any amplifier system. Please read our post on how to find the best spot to place your exterior antenna and get the best results. That being stated, it is critical that an antenna placement be in a spot which maximizes the potential for a cellular device or a cellular booster to get the best signal. For the cell phone signal booster antenna, the purpose is for an antenna to scan an area for signals and then to relate the signal to the booster so that it can be amplified. If you consider a television antenna, the purpose is to capture the signal in air and relate that back to your TV set. Like most antennas, an internal and external antenna is designed to capture and transmit a signal properly. What part does an antenna play in signal boosters? An example of a vehicle exterior cell phone signal booster antenna would be the cell phone passive signal booster or repeater antenna. Commercial grade residential signal boosting products tend to have a stronger amplification and more bells and whistles to increase performance as the spaces that these signal boosting routers cover generally exceed 10,000 square feet. This article will explain the main differences between the two, primarily for a residential and office based setting. ![]() Each of these components are important factors in considering which signal booster to get. Signal Boosters have internal and external antennas.
