How a cell phone booster works

how a cell phone booster works

1 - Outdoor antenna

The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas be either directional or omni-directional.

2 - Cellular amplifier

The amplifier (or "repeater") boosts the signal coming and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

3 - Indoor antenna

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.

Customer testimonials

"Thanks for your great customer service and commitment to getting my repeater kit installed and working correctly. You deserve the excellent reputation you have with your customers." - Charles Wicker, Sherwood Farm Group

"I set it up my repeater kit here in East Texas this weekend. After hooking everything up I instantly had 4 out of 5 bars. Previously with just the phone I was getting 1 bar inside & a flickering 2 bars outside with frequent dropped calls." - Jay Davis, HTJ Consultants.

"RepeaterStore's signal experts were very knowledgeable and helped me pick out the right antenna and I'm now getting double the download speed on my Verizon data card. I went from 1-2 bars of shaky signal to consistent four bars, and my download speeds have increased from a range of from 200 to 800 kbps. The fast and free shipping was wonderful - I recommend them highly." - Jim Martin
