Signal Boosters have internal and external antennas. Each of these components are important factors in considering which signal booster to get. Find out more here. This article will explain the main differences between the two, primarily for a residential and office based setting. 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.
What part does an antenna play in signal boosters?
Like most antennas, an internal and external antenna is designed to capture and transmit a signal properly. If you consider a television antenna, the purpose is to capture the signal in air and relate that back to your TV set. 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. 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. Please read our post on how to find the best spot to place your exterior antenna and get the best results.
Types of signal booster antennas.
Antennas are a key component of any amplifier system. Donor antennas are installed on the roof or near a window and bring the outdoor signal in. 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. Both types of antennas connect to the amplifier unit via coaxial cable. Depending on the need, multiple antennas may be required.
Types of interior signal booster antennas.
Dome antennas radiate signal in all directions so they are ideal for ceiling installation in center of large square or circular spaces. They must be used for single level/floor reception boosting purposes.
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 can be installed on ceilings if cellular boost is needed across multiple floors.
Perform a site signal survey first for installing exterior antennas.
The first step in setting up an outdoor antenna, more accurately called a donor antenna, is to complete a cell signal survey. 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.
Types of donor antennas (exterior antennas).
Donor antennas are the outdoor antennas which pull in the existing signal to be amplified inside a building. There are two types of donor antennas to choose from: omnidirectional and directional - also called "Yagi".
The omnidirectional (omni) antenna receives signal from a 360-degree field, meaning it can pick up radio-frequency (RF) waves from all directions.
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.
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.
Choosing an Omni vs. a Yagi Donor Cell Signal Antenna.
In many commercial environments, building owners want to improve their cellular signal for all carriers and on all frequencies. In a broadband commercial environment, this is possible with commercial-grade cell signal booster systems, which include outdoor cell signal antennas that are installed on the roof to bring an outdoor cell signal inside.
Determine which type of donor antenna to install.
In order to determine which antenna is best for the installation, an integrator needs to consider where the signal is coming from, how strong it is, and what, if anything, might be interfering with that incoming signal.
Many installers prefer to start planning the design with an omnidirectional antenna, which will capture all available signals outside. For buildings with very poor reception, this may be the best choice. Because an omni antenna detects signals from various towers and carriers, it can amplify those signals indoors so that all incoming cellular devices can experience improved coverage.
In some cases, however, conditions may present the need to use one or more Yagi antennas - This is true when outside signal strength is VERY weak. Pointing these antennas directly at a cell tower is ideal for environments where the outside signal is especially weak (or very strong), and demands fine-tuned signal strength control. Pointing a Yagi at a very weak signal (more than 80 dB) can help pick up every bit of those radio frequency waves while disregarding everything else. Likewise, in the case of very strong signals (less than 45 dB), an installer can point the Yagi slightly away from the tower in order to bring in the right amount of signal without overloading the system.
When installing a cell signal booster system, be sure to take all data into account before choosing the type of donor antenna to install. Perform a site signal survey first, determine the strength of the signal, then decide which antenna would result in the strongest indoor signal.
