The SureCall TriFlex Signal Booster Kit is a tri-band wireless signal booster. It supports Voice and 3G for all carriers, and 4G for a single carrier, depending on the model chosen.

It covers an area of up to 6,000 square feet, multiple simultaneous users and includes a 3-year warranty.

All carrier frequencies are independently balanced with easy to use adjustable control dials. The SureCall TriFlex is approved by all major carriers and equipped with built in safeguards to completely eliminate interference to cell towers.

• Highest 4G data rate in the industry
• 65 dB cellular, 72dB PCS, 63.5 dB LTE
• Fully compliant with new FCC certification standards
• Auto Gain Control (AGC) and manually adjustable dB gain and attenuation
• Dual Embedded CPU
• Eight RSSI detectors for all inputs and outputs
• Configurable for all indoor environments

The SureCall TriFlex cellular booster kit can be customised with several different amplifier and antenna options:

The TriFlex-A Amplifier boosts most major 2G and 3G carriers plus the AT&T & US Cellular 4G LTE networks.

The TriFlex-V Amplifier boosts most major 2G and 3G carriers plus the Verizon 4G LTE network.

The TriFlex kit also comes with a choice of two outside antennas:

The SC-288W Omni Outdoor Antenna has 4dB gain. Omni antennas receive and send signals in a 360º radius. They can receive signals from multiple cell towers and is best for boosting signal on many different carriers. They are excellent in most situations where the existing outside signal strength is moderate to strong. If the outside signal is weaker than that, you may need the directional yagi antenna instead. We have a guide to testing your outside signal strength here.

The SC-230W-S Yagi Outdoor Antenna has up to 8dB of gain. It is a directional antenna that can reach cell towers up to 30 miles away. It needs to be set up pointing in the direction of the cell tower, and because it is directional it will only pick up signal in that direction. It's very powerful at picking up weak signal in one particular direction, and we recommend it for situations where existing outside signal is weak, and you only want to boost coverage for one carrier (or if more than one carrier has a cell tower in that direction). If you need to boost signal coming from different directions, it is possible to set up more than one yagi antenna. Contact us for more help with this.

Finally, the TriFlex kit also has a choice of two inside antennas:

The SC-222W Omni Dome Antenna is a multi-band omni-directional plastic dome antenna with that gathers signals from all sides. It has 6dB gain and is designed for central locations with 360º coverage. The range of the antenna is dependent on three factors: 1) physical obstructions, 2) power generated by the booster and 3) reception from outside signal received and distributed by the outside antenna. Besides the antenna itself, parts include mounting equipment. It needs to be mounted to the ceiling for best results and you will need to run a cable to the back of the ceiling.

The SC-248W Panel Antenna is a directional antenna with up to 10dB gain. Panel antennas allow optimum reception to targeted areas. It can be mounted to either the wall or ceiling.

The SureCall TriFlex repeater has a powerful 72 dB gain. Because this is a powerful amplifier, you must have a minimum of 20 ft of vertical separation between the inside and outside antennas. Adding up to 75 feet of horizontal separation will help improve the performance of the kit by minimizing the potential for oscillation (feedback) between the inside and outside antennas.

We recommend using a lightning surge protector in most cases, but particularly if you'll be installing the kit in an area with frequent lightning. The lightning surge protector should be installed in line with the cable and near the outdoor antenna, and should be properly grounded.
