Overview
A Verizon-band signal booster for the home, tuned to band 13 (700MHz) so it works with Verizon and networks that ride on Verizon towers, including Straight Talk. Suits a house, cabin or small office with weak Verizon bars, not other carriers.
This is a single-carrier device, built around the 700MHz band 13 that Verizon and Verizon-network resellers such as Straight Talk use, so it will not help an AT&T or T-Mobile phone. Like most consumer boosters, the advertised 5000 square foot or 2-5 room range assumes there is already some outdoor Verizon signal to amplify; a true dead zone with zero bars outside will see far less gain. The automatic gain control and LED status light keep the unit from overloading rather than add extra range on their own.
- 700MHz band 13, Verizon and Verizon MVNOs only
- Up to 65dB gain with automatic gain control
- Rated for up to 5000 sq ft or 2-5 rooms
- FCC approved, 3 year warranty
Who it's for
Homeowners, renters or small offices on Verizon or a Verizon MVNO like Straight Talk who get 1-2 bars indoors but a usable signal outside. Not for anyone on AT&T, T-Mobile or a carrier outside the 700MHz band 13 frequency.
Strengths and trade-offs
Drawn from this product's published specifications.
- Targets the 700MHz band 13 that Verizon and Straight Talk run on
- Automatic gain control adjusts to signal strength without manual tuning
- Small, portable unit with a sleep mode and LED status indicator
- FCC approved with a 3 year warranty
- Only helps Verizon and Verizon-network carriers, not AT&T or T-Mobile
- Advertised square footage assumes a livable outdoor signal already exists
- No customer reviews yet to confirm real-world range
Performance notes
The booster picks up the existing outdoor Verizon signal, amplifies it up to 65dB of gain, and rebroadcasts it indoors, so the ceiling on performance is whatever signal reaches the roof antenna to begin with. Automatic gain control adjusts the amplification level to the incoming signal strength to avoid overload, and an LED shows the working state. Coverage claims of up to 5000 square feet or 2-5 rooms apply in open floor plans with decent outdoor reception; thick walls, metal siding or a weak outdoor signal will shrink that footprint.

How much space can this signal booster cover?
The listing rates it for up to 5000 square feet or 2-5 rooms, though that figure assumes a usable Verizon signal is already reaching the building from outside.
