Product Details

The EFlex 65 Adjustable Signal Booster Kit is one of our most popular systems. This dual-band kit will boost most carrier's 2G and 3G networks over an area of up to 5,000 sq ft depending on your outside signal strength.  It supports multiple carriers and phones/data-cards simultaneously so it's perfect for homes and small offices.

The SureCall Flex Pro 65 Adjustable Signal Booster Kit features an omnidirectional outside antenna allowing it to boost the signal from multiple carriers simultaneously.  If you only need to support a single carrier and you have a 3 bar signal or less of existing outside signal, our EFlex 65 Yagi kit may be a better option. This system requires at least 20 ft of horizontal or vertical separation between the inside and outside antennas with up to 50 ft. of separation required for maximum performance.


Kit Options

This EFlex kit includes a choice between two types of inside antennas.  

Dome Antenna
A dome antenna is an omnidirectional antenna that is ideal for covering a signal floor.  A dome antenna is typically mounted to a ceiling by drilling a hole threw the ceiling.  This requires that you have access to the backside of the ceiling material, either through an attic or if the ceiling uses drop-ceiling tiles.

Panel Antenna
A panel antenna is a directional antenna that is best at covering multiple floors or long and narrow spaces.  Panel antennas can be mounted to a wall, a ceiling, or they can rest on top of a ceiling tile or on the floor of an attic to cover the area below. 



The SureCall Flex Pro 65 Adjustable Signal Booster Kit boosts the standard dual-band frequencies of 800 and 1900 MHz which are widely used in North America.  The following carriers are supported:

  • AT&T 2G, 3G and 4G HSPA+ (not 4G LTE)
  • Verizon 2G and 3G
  • Sprint 2G and 3G
  • T-Mobile and Cricket 2G
  • Virgin Mobile 3G

This system does not support LTE, WiMAX, Nextel/iDEN/MIKE, or AWS networks.
