Booster Frequently Asked Questions:

How is DA4000 different than that 'Booster Patch' that is selling for $20 or less and sticks on between your battery and the cell phone?
Simply put, the 'Patch' is a gimmick that is not FCC approved and does nothing besides gives the owner the false sense that it really is doing something. Our cellular-powered Booster operates at 12 volts and changes your .6 watt cell phone to a 3 watt cell phone, increasing the actual power output by 500%. The patch might as well be a Happy Face sticker.
 
I heard that you cannot amplify Digital signals. Is that true?
No. You can amplify digital signals in the same way analog signals are amplified. All of the Boosters we sell amplify digital signals.

My phone shows some signal but I can't get through or my calls are dropped. Will the Booster help me?
If your phone does not indicate "no service", then the Booster will increase the signal strength in both the reception and in the transmission ability. Many times you can receive the service provider tower's signal but you don't have enough power for the tower to hear you. The Booster helps increase the strength of the transmitting signal from your phone by 20 dB.

Will the Booster guarantee that no calls will ever be dropped?
No. Cellular communication is highly directional. Cellular towers have antennas that point in a certain direction. If the tower is not pointed toward where you are, and no signal is present, there is nothing that can be done to create the signal. Cellular communication is dependent on the cellular phone service provider. Many calls are dropped as a result of full towers that cannot accept a handoff from another tower. There are also software problems and failures of the actual cellular broadcasting equipment. Cellular phone transmission can be shadowed by buildings in the line of sight path between your phone and the tower. However, you should notice a big difference in the quality of the calls that you receive, as well as in the frequency of dropped calls.
 
 
I have a PCS Sprint phone. Will the Booster help?
The DA4000 is designed to amplify any signal at the 1900 MHz range, which is the frequency in which PCS operates.
 
 
My cellular phone is not listed as a choice for your Cable Adapter. What do I do?
Please email us and we will find out if an adapter exists for your phone. We do have passive adapters that fit around the antenna, but they are not as good as a direct connect. Several phones do not have an external antenna port at all. This passive adapter will work with most of them.
 
 
I use my cell phone on my boat. Will the Booster work for me and what will be the range that I can expect?
Yes, the Booster will work, provided that the signal is pointed in your direction from the land-based towers. Several users of our Booster have reported good results as far as 50 to 60 miles offshore. However, they are also using a quality marine cellular antenna. You can purchase the entire assembly if you require a marine antenna. Please see our selection of antennas here.
 
 
I have an existing car kit and cradle that I use for my phone. It already has an antenna installed on my car. Can I use the Booster?
Yes. You will need to attach the Booster in between the external antenna connection of the car kit and the antenna. You must purchase the  crimp on connector with the Booster. Please have a proper car electrician attach the system.
