Product Description

Wilson Pro 70 PLUS Office PRO MAX (4 Antennas) 463127


  • Designed for performance and heavy load, both voice and data.
  • Designed for offices up to about 40,000 sq. ft
  • Best-in-class coverage area.
  • Carrier agnostic: Works with all major cellular carriers.
  • Boosts 4G LTE and 3G service for voice, text, and data.

  • Graphical uplink and downlink power meter.
  • Boosts cell signal in small offices for multiple users.
  • Includes commercial-grade antennas and coax cables.

This Wilson Pro 70 PLUS Office PRO MAX system is a four-antenna option designed for small offices or building areas that need improved cell signal reception and have high user and data demands. This system improves both voice and data to reduce dropped calls and missed emails and texts, keeping your business and employees connected with a stronger cell signal.

This kit includes four (4) inside dome antennas that send amplified signal to the phones in your office in four different areas. The idea of using 4 antennas is to be able to disperse more evenly boosted cell signal into 4 different zones. It is not necessarily four times the coverage, but rather more even coverage in a larger area.

Please Note: The diagrams below are only examples of 4 antenna configurations. Additional coax cable may be required in the Wilson Pro PLUS Office PRO MAX kit to achieve the following examples. Powerful Signal will be glad to give you guidance on cabling and coverage for this system in your office environment.

Who is this for?

  • Those who have heavy cellular user and data loads.
  • Those who have a multiple areas that need better cell signal
  • Those who frequently experience dropped calls, undelivered text, or slow 4G data.
  • Small offices in urban locations with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Small offices below ground level, and other places where cell reception is poor.

How it works

Using Wilson Electronics' patented SmarTech III® technology, the Wilson Pro 70 PLUS receives the outside cell signal, amplifies it, and rebroadcasts it inside your office through the four inside dome antennas. This allows you to stay connected in areas where cell service is poor, or where your office's building materials interfere with signals from the local cell tower. (See the "More Information" tab for details.)

Works with all major cellular carriers

The Wilson Pro 70 PLUS Office Pro MAX works with all major wireless carriers, including VerizonAT&TT‑MobileSprintU.S. Cellular, and most others.

How much area will this product cover?

The following chart is based on mostly open interior space with no obstructions (walls, doors, etc.). Drywall, plaster, wood, concrete, steel, and stone all affect radio transmissions. Cell phones also operate in several different frequencies that penetrate obstructions differently. In general, the stronger the outside cell signal, the greater the interior broadcast distance. Please contact us if you have any questions about coverage for this booster.

Outside signal strength
Approximate coverage area
Weak (−100 dBm)
Not recommended
Moderate (−90 dBm)
Up to 12,000 sq ft
Strong (−80 dBm)
Up to 45,000 sq ft

These coverage area estimates have been calculated from industry standards and Powerful Signal's years of experience installing cellular amplification systems. Powerful Signal considers any figures from other retailers that exceed these to be inaccurate and unrealistic.


In an office environment, it's best to have your Wilson Pro system installed by a professional. A professional installer will have knowledge of local building codes, and have the proper tools and experience to make sure your system is set up and configured correctly.

How does a building cell phone signal booster work?

A building cell phone signal amplifier system is made up of four major components:

  1. A cell phone signal amplifier and power supply.
  2. An outside donor antenna.
  3. An inside broadcast antenna.
  4. Coax cables that connect the antennas to the amplifier.

Cell phone signal amplifier

The cell phone signal amplifier—sometimes called a booster—is the core component of the system.

The amplifier is bi-directional: It amplifies both the signal your phone receives from the tower and the signal your phone sends to the tower. A weak cell signal is received by the outside antenna and amplified by the booster; the strengthened signal is then rebroadcasted by the inside antenna to your phone. The amplifier also boosts the connection back to the cell tower. (There still has to be some cell signal for the booster to amplify, though; it cannot “multiply zero”).

The most convenient spot to place the cell phone signal amplifier is in an I.T. closet, network box, attic, or garage; this will keep it out of sight, but still accessible if you need to make any changes to the system. The location you select to install the amplifier needs to have a 110-volt AC wall outlet nearby (typically within 6 feet) to plug in the amplifier’s power supply.

Directional and omnidirectional antennas

Donor antennas: directional (left) and omnidirectional (right).

Outside donor antenna

The donor antenna communicates with your wireless carrier’s cell tower. It’s typically mounted on a pole on the roof of the building, clear of any surrounding obstacles.

Some donor antennas are directional, meaning they need to be pointed toward the strongest nearby cell tower. Typically you’ll choose a directional antenna if your building is in a remote location with one distant cell tower providing weak outside signal.

An omnidirectional antenna picks up signals from multiple cell towers in different directions. Usually you’ll choose an omni antenna if your building is in an area with several surrounding towers, and especially if you have plenty of outside cell signal that just isn’t penetrating inside your building.

The outside antenna needs to be placed with adequate separation from the inside antenna(s), and, if you’re using a directional antenna, not pointing toward your inside antenna(s) so their signals overlap. Without adequate separation, the outside and inside antennas may conflict with each other (a condition known as oscillation), which will cause the amplifier to reset or shut itself off.

For more information about choosing the right donor antenna, see our blog entry, “Directional or omnidirectional: Which antenna is best?

Panel and dome antennas

Broadcast antennas: panel (left) and dome (right).

Inside broadcast antenna

The broadcast antenna communicates with cell phones inside the building. It’s typically mounted on a ceiling or a wall.

A dome antenna is mounted on the ceiling, and broadcasts its signal downward in a 360° pattern. Domes work best in situations where the ceiling is level with the floor (not angled), low enough to be reached with a ladder, and where there is access above the ceiling to attach coax cable to the antenna. Domes typically provide the best signal coverage, and are also less noticeable than panel antennas.

A panel antenna is mounted on a wall, and broadcasts its signal forward, away from the panel, in a beam 60–70° wide. Panels work best in situations where a dome antenna is not easy to install or would not be horizontal to the floor, or where pulling cable through walls and ceilings is not an option. Panels can be concealed in recessed areas behind drywall.

Basic cell phone signal amplifier kits usually include one broadcast antenna. Larger, more complex buildings with custom-designed systems have multiple inside broadcast antennas that cover more area.

400, RG6, and RG58 coax cable

Terminated coax cable: 400 cable with N‑connector (left), RG6 cable with F‑connector (middle), RG58 cable with SMA‑connector (right).

Coax cable

Lengths of coax cable connect the donor antenna and the broadcast antenna(s) to the cell phone signal amplifier.

Any signal sent through a cable is going to result in attenuation (signal loss). Since the objective of installing a cell phone signal amplifier system is to increase signal, the length and type of cable in the system is an important consideration.

Commercial and large-home systems use 400-type coax cable or plenum coax cable, terminated with N‑connectors. These cables are very thick and have very low signal loss, which makes them ideal for long runs from the amplifier to the antenna (sometimes hundreds of feet). They are, however, very rigid, so they’re not well-suited for use around corners and in tight spaces. These types of cables are often used by professional installers.

Small home amplifer systems typically use RG6 coax cable, terminated with F‑connectors, the same found in everyday cable and satellite TV systems. Compared to 400 coax, RG6 has more than twice the signal loss per foot, but it is also much thinner and easier for consumers to work with. (Homeowners who need long runs of cable might want to consider using RG11 coax cable with F‑connectors; RG11 is more rigid and expensive than RG6, but has much lower signal loss.)

Single-room amplifiers often use RG58 coax cable with SMA‑connectors. This is the thinnest cable for in-building systems. Because of its high signal loss (60% greater than RG6), it’s suitable only for the shortest runs.

Optional components

The four parts above are all that’s required for a complete cell phone signal amplifier system. Other components can protect or enhance a system:

  • A lightning surge protector insulates the amplifier against a sudden electrical surge from a lightning strike to the donor antenna.
  • Splitters and couplers divide the signal from an amplifier to two or more broadcast antennas, expanding the signal coverage inside your building. (These should only be used with commercial or large-home amplifiers, and where there is adequate outside signal.)
  • Attenuators can be used when the outside signal is so strong that it’s overwhelming the amplifier. (These should only be used with professionally-installed commercial amplifiers.)
