The SolidRF Fiber DAS 4400 provides cellular reception in large buildings of all types, at industrial and utility sites, and for many other applications.
The system’s Master Unit (MU) receives signal from one or two outside donor antennas. The MU amplifies the signal it receives and sends it via a fiber-optic cable to a Remote Unit (RU). The optical fiber trunkline can be as long as 3,300 feet (1 km) without any significant loss of signal. The RU again amplifies the signal it receives and distributes it to cell phones and cellular devices via inside dome antennas. Each RU has four antenna ports—one RU can support one to sixteen antennas, depending on outside signal strength.
The SolidRF Fiber DAS 4400 provides strong cellular voice and faster data speeds for multi-story buildings and large facilities that other commercial cellular amplifiers are unable to handle and at a fraction of the cost of a carrier-installed active DAS system.
* This add-to-cart system includes 100, 250, 500, or 1,000 feet of fiber-optic trunkline cable. Please contact us for inquiries about longer or custom runs of optical fiber.
** 100,000 square feet per RU is possible with strong outside cell signal. Please contact us for more information.
The SolidRF Fiber DAS 4400 system includes 400-type coax cable to connect the Remote Unit to the inside antennas. If your building requires fire-rated cable in plenum spaces, you may upgrade to half‑inch plenum air coax by choosing the product option at the top of this page. Plenum cable fully meets state and federal building codes.
Half-inch cable also has nearly half the signal loss per foot of cable compared to 400-type coax cable, delivering stronger signal from the SolidRF amplifier and a larger indoor coverage area for phones and other cellular devices.
(Half-inch plenum cable is available at additional cost. Please contact Powerful Signal for more information about plenum-rated components.)
In a large building, office, or warehouse, you’ll get the best results and performance from the SolidRF Fiber DAS 4400 with a custom design and professional installation.
Working with your floor plans, Powerful Signal’s design engineers will create design specifications that will use the fewest number of components to get the maximum amount of cellular coverage inside your building.
Powerful Signal’s 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.

The SolidRF Fiber DAS 4400 can be self-installed if you are familiar with cellular amplification equipment. We’ll be happy to advise you on the best placement of antennas or provide a custom, turnkey solution. If you purchase this system as a standalone product, it includes the following components:
The SolidRF Fiber DAS 4400 Master Unit (MU) receives available outside cell signal, amplifies it, and transmits it via fiber-optic cable to one or more Remote Units (RUs). Each RU amplifies the signal again and rebroadcasts it inside your building through one to four antennas.
This active DAS system allows you to stay connected in areas where cell service is poor, where your building’s construction materials interfere with signals from local cell towers, or in other situations where cellular service is not available inside your facility.
The SolidRF Fiber DAS 4400 works with all major wireless carriers, including Verizon, AT&T, T-Mobile, Sprint, UScellular, and most others.
It operates on common cellular frequencies.
Each Remote Unit includes four dome antennas that broadcast improved cellular signal in a spherical pattern. The radius of that sphere depends on many factors, including:
Under optimal conditions, with no interior obstructions, you can expect the following approximate coverage areas, based on outside signal strength and the number of Remote Units (RUs) and installed antennas:
This commercial-use fiber DAS amplifier is protected by SolidRF’s full warranty. It is returnable only for warranty-related issues. The purchaser is encouraged to consider a designed system from Powerful Signal or, if opting for self-installation, to thoroughly understand how cellular amplifier systems are set up and operated and to consult with Powerful Signal before and during installation regarding best practices for optimum performance of the amplifier and its components.
SolidRF signal amplifiers are warranted for three (3) years against defects in workmanship and/or materials. Warranty cases may be resolved by returning the product directly to Powerful Signal with a dated proof of purchase. (See Powerful Signal’s return policy.)
Signal amplifiers may be returned directly to Powerful Signal at the purchaser’s expense, with a return merchandise authorization (RMA) number supplied by Powerful Signal. Powerful Signal shall, at its option, either repair or replace the product. Powerful Signal will pay for delivery of the repaired or replaced product back to the original purchaser if located within the continental United States.
This warranty does not apply to any signal amplifiers determined by Powerful Signal to have been subjected to misuse, abuse, neglect, or mishandling that alters or damages physical or electronic properties.
Failure to use a surge-protected AC power strip with at least a 1000 Joule rating will void your warranty.
All SolidRF products that are packaged with other SolidRF accessory products are intended for resale and use as a single unit, and such product kits are required to be sold to the end user or subsequent reseller as packaged. The “de-kitting” and sale as a standalone product of any one or more components of such a product kit is in violation of SolidRF’s warranty. No “de-kitted” product will be eligible for return for any reason. (The sale of separate, not-kitted cable, antennas, and other accessories is allowed and fully warranted.)
SolidRF components and accessories are warranted for 90 days against defects in workmanship and/or materials.
This warranty does not apply to any accessory or component determined by Powerful Signal to have been subjected to misuse, abuse, neglect, or mishandling that alters or damages its physical or electronic properties.
