Introducing the Office 300
The Office 300 is a complete cell signal system for your building. It pairs our bestselling multi-carrier amplifier with a high-gain roof antenna and two low-profile ceiling domes to bring reliable signal to every device on every network inside of your business.
Day to day, that means your people make and take calls at their desks instead of stepping outside, your customers stay connected while they're with you, and the hotspots, alarm panel, and card readers ride the same boosted signal. The complaints just stop.
It's also completely handled for you. The antenna choices, the 50-versus-75-Ohm question, the cable runs, and the placement decisions that stall most booster installs are either built into the system or settled by the crew at your building. Nothing plugs into your network, and nobody sets anything up on their phone.
The price covers everything you need from start to finish, including the team that installs it, the initial signal analysis, hardware placement, the installation itself, tuning, troubleshooting, and the final walkthrough.
It's built for the office that needs the signal fixed more than it wants another project. Your only homework is checking the bars on a phone outside, and the coverage table below turns that reading into an answer.
At a glance

Reliable calls & data in places that are currently dead zones
The installer will strategically mount the inside antennas to provide boosted signal to the areas of your business that need it most.
White glove service with a 100% satisfaction guarantee
The installers handle every part of the installation. If you're not happy, they'll come back out and make it right, or if that's not possible, refund you in full.
You can see it working in real time.
The amplifier's LCD shows you the status of the booster, band by band, resulting in a better installation and easier troubleshooting.
No monthly fees or extra charges, even if you change networks
The Office 300 boosts every band the FCC allows, so it will continue working even if you change carriers or move to a new network. One purchase, no monthly fees.
How the Office 300 Works
The Office 300 works by receiving the existing cell signal from nearby towers, amplifying it, and then broadcasting it throughout the building for better connectivity. We've walked through each step below in more detail.
The outside antenna receives the existing cell signalfrom the nearby cell towers and passes it over a low-loss cable into the building.
The amplifier receives & boosts the cell signalby up to 72 dB, the max boosting allowed by the FCC, and then passes it to the inside antennas
The two inside antennas broadcast the boosted signalthroughout the building, so you get reliable connectivity in every part of your business.
Why pay more for the Office 300
It's no secret that you can purchase the exact same setup with the Office 200 for a cheaper price, so why should you go with the Office 300?
It all comes down to resources and time.
If you have a crew that can run cable and install antennas, then you don't need the Office 300's included professional installation, so the Office 200 is the better solution for you.
If you don't have an installation team ready to tackle this project, then the Office 300's included professional installation is your best choice and absolutely worth the price.
Should you buy the 200 instead?
Do you have a facilities crew that can run cable and install components? Choose the Office 200 and we'll help you select the perfect setup for your space.
How Much of Your Building Will It Cover?
The amount of coverage that the Office 300 can provide is determined by your existing outside signal and the density of your building.
Weak outside signal: 1 to 2 bars, about -100 dBm
Moderate outside signal: 3 to 4 bars, about -90 dBm
Strong outside signal: 5 bars, -80 dBm or better
No usable signal outside? Then a booster can't fix it, and we'll tell you that before you spend anything. Not sure? Call us at 1-888-974-8237.
Coverage figures are estimates. Exact coverage will depend on your outside signal, building materials, and layout.
Need more coverage in your building?
There are two options. The first is to purchase a second Office 300 and install both in your space. This should provide double the coverage, depending on cable runs and antenna placement. If you decide to go this route, please let our team know so we can help coordinate the installation work.
The second option is to work with our commercial team to design a custom solution for your space. This would ensure the best result and we can discuss different installation options at that point.

How the Installation Works, Start to Finish
Here's exactly who does what and when.
Receive the Equipment
Once you place your order, we'll ship your equipment (antennas, amplifier, and components) directly to your door.
Schedule the Installation
Inside the box you receive will be an installation card with a unique code. Follow the instructions on that card to schedule your installation at a date and time that's convenient for you.
Be Prepared
Let the installer know in advance if you have very high ceilings or roof access is limited. If you don't own the building, then you'll need to receive permission and roof access in advance. If you need help, we can help you coordinate with the installer.
System is Installed
The installer will perform a site survey, review the building for cable runs and mounting options, and then will perform the install. They'll then do a post-installation review to ensure that the system is providing reliable, boosted signal, and sign off with you, the customer.
Who installs it: licensed and insured crews that are certified to install the Office 300.
Note: If you've purchased multiple Office 300s then please let us know so we can link the installations together so the installer only makes one trip.
