About
The dead-zone killers since 2002
Wi-Ex — Wireless Extenders — began in 2002 with a simple observation: the signal was already there, the phone just couldn't reach it. So we built the zBoost line to extend it.
The story
The first zBoost units solved a problem carriers couldn't: the last hundred feet. Towers covered the street, but concrete basements, metal roofs and rural edges stayed dead. Two decades later the problem hasn't changed — and neither has the fix.
Today the store carries the full lineup: home boosters up to 10,000 sq ft, vehicle repeaters, directional antennas and every cable you need between them. All FCC-certified, all carrier-approved, all backed by a 60-day dead-zone guarantee.
Principles
How we work
No internet required
Unlike Wi-Fi calling, a booster fixes the cellular signal itself — it works when your internet doesn't.
Carrier-approved
FCC-certified and registered under every major US carrier's booster program — legal and listed.
60-day guarantee
Test it in your actual dead zone. If it doesn't raise your bars, full refund — no questions.
What a booster fixes (and what it can't)
- Fixes: weak indoor signal, basement and interior dead zones
- Fixes: dropped calls on rural edges and highway gaps
- Fixes: buildings where walls and roofs block coverage
- Can't fix: a true zero-signal area — there must be a faint signal to amplify
- Always: free US shipping and phone support from people who install these
