Features of the SolidRF Signal Plus

  • Provides two zones of coverage in any size home or home office.
  • With up to 68 dB gain, offers two to six times the gain of other boosters in its price range.
  • Sturdy aluminum booster case with integrated heat sink and LED status lights.
  • Boosts 5G, 4G LTE, and 3G service for voice, text, and data. (Learn more about 5G compatibility.)
  • Boosts cell signal for multiple users in your home or home office.
  • Works with the networks of all major U.S. cellular carriers.

The SolidRF Signal Plus is a two-antenna cell signal booster system is designed for both large and small homes that need improved cell signal reception throughout the house. The Signal Plus improves both voice and data quality to reduce dropped calls and missed messages, keeping your family members, friends, and guests connected with a stronger cell signal.

This system includes two inside panel antennas that send amplified signal to the phones in your home.

Who is the SolidRF Signal Plus for?

  • Those who frequently experience dropped calls, undelivered texts, or slow data rates.
  • Homes and home offices in remote locations with weak cell service (new communities, rural areas, cabins, etc.).
  • Homes and home offices with building materials that block outside cell signal (plaster, concrete, metal, UV-coated windows, etc.).
  • Homes with basements, theater rooms, metal out-buildings, and other places where cell reception is poor.

Do-it-yourself installation

You can install the SolidRF Signal Plus yourself in a couple of hours. (See Documentation, below, to download the user manual and quick installation guide.)

Alternatively, you can have a professional install your booster system at additional cost. We recommend that you contact a local cable/satellite TV installer; the work required to install a cell signal booster is similar to installing a satellite dish TV service.

How the SolidRF Signal Plus works

The SolidRF Signal Plus receives available outside cell signal, amplifies it, and rebroadcasts it inside your home or home office. This allows you to stay connected in areas where cell service is poor or where your building’s construction materials interfere with signals from local cell towers.

Works with all major cellular carriers

The SolidRF Signal Plus works with all major wireless carriers, including Verizon, AT&T, T-Mobile, Sprint, UScellular, and most others.

It operates on common cellular frequencies.

  • 700 MHz (SMH) bands 12, 13, 17.
  • 850 MHz (Cellular 850) band 5.
  • 1700/2100 MHz (AWS) band 4.
  • 1900 MHz (PCS) bands 2, 25.

How much area will the SolidRF Signal Plus cover?

The coverage area this system can provide depends on many factors, including:

  • Outside signal strength received by the donor antenna.
  • Inside building materials. (Cellular frequencies pass through wood framing and drywall more easily than through steel, stone, or concrete.)
  • The cellular frequencies used by the carrier. (Lower-frequency SMH and CLR signals travel farther than higher-frequency AWS and PCS signals.)

In general, the stronger the outside cell signal, the greater the interior broadcast distance. With strong outside cell signal (−95 dBm RSRP), this system can typically cover 8,000 square feet of indoor space with 700 MHz signal. With weak outside signal−115 dBm RSRP), it can typically cover 1,000 square feet of indoor space.
