No sign-up. Just answers from your own numbers.
Should you buy a booster?
Five questions. It may tell you not to buy one.
What will the box rating really cover?
Turn an “up to” number into a figure you can plan around.
Planning range, not a guarantee. The weakest band uses a published 1,000 to 2,500 sq ft figure for a 5,000 sq ft kit. The other bands are our own estimates, because makers rarely publish them.
How much signal does your cable eat?
Work out cable and splitter loss before you drill any holes.
Figures come from each maker’s datasheet. Your own cable’s datasheet is always the better number.
Which way should the antenna point?

Booster Finder
Find the right setup for your space
Answer a few questions. You’ll get the kit type, the specs to look for and the guides to read next.
The Finder matches your answers to a setup type and our guides. Coverage targets are planning estimates. It names no products because we only recommend hardware we have examined.
How it works
Three steps to the right fix
Step 1
Measure
Take a dBm reading indoors and outside, at the spot an antenna could mount.
Step 2
Diagnose
Find out if the problem is the building, the carrier, signal quality or distance.
Step 3
Fix
Choose the cheapest fix that solves it. Often that isn’t a booster.
Straight talk
When a booster is the wrong answer
Most booster sites exist to sell you one. Here are three cases where you should keep your money.
Nothing usable outside
Below about -115 dBm outdoors, a booster has almost nothing to amplify.
Strong signal, bad service
If the reading is strong, the problem is usually quality or congestion.
Solid home internet
Free Wi-Fi calling may fix indoor calls and texts on its own.
If a booster is the right fix
Why it can be worth buying
One-time cost
Basic home kits start around $200. What boosters cost
No monthly fee
A booster is hardware. Your carrier plan stays the same.
Every phone benefits
One wideband booster can serve several carriers at once. How that works
Room to back out

Who’s behind this
Started in a freezing Buffalo driveway
In 2018, Arif Hossain was standing outside in the cold to catch one bar of 4G. The help he found online was either engineering manuals or shallow review pages.
Today he’s a telecommunications network technician who has mapped, installed and optimized hundreds of boosters for homes, RVs and commercial buildings. This site is the plain-English guide he wanted back then.
Know the fix before you pay for it
It takes about two minutes to find out if you need a booster.
