Frequently Asked Questions
1. What kind of improvement in cell phone performance can I expect with the Amplifier Kit?
The amplifier kit's performance will depend somewhat on the strength of the cellular signal outside your home or building. However, if you install the amplifier in accordance with the instructions, you can expect a significant improvement in your ability to use your cell phone or cellular data card indoors.
2. Where should I install my repeater to get the best coverage?
You should install the amplifier in the area where you most need an improved signal. The farther you are from the amplifier, the less improvement you will experience. It is also important to install the outside antenna in a location where you have the strongest outside signal. Also keep in mind the distance between the amplifier and the outdoor antenna. You will need at least 20 feet of separation to prevent the start of unstable oscillation, but you will probably want to stay within the 50 foot length of the coax cable. We have additional optional cable and the necessary connectors / splitters should you need to install more than one indoor antenna to cover more areas, but using more cable will result in some signal loss.

3. I have a 1800MHz phone – will the Amplifier boost that signal?
The Amplifier is designed to work with the GSM Cellular 900MHz bands. We offer specific amplifiers for other specifications.

4. Can I use my own cable for my installation?
The low loss RG6 cable included with your product has been specifically selected for the Amplifier kit. Use of another type or longer length of cable will likely degrade the system’s performance. Contact us to tailor a cable for you should you require longer cable length.

5. Can I use different antennas than the ones supplied in the box?Yes! The amplifier kit is designed to give you reliable signal improvement with the included antennas. We offer optional GSM antennas and accessories that enable you to customize your amplifier kit to your specific needs.

6. There are many people using cell phones in my office at the same time – will the Amplifier improve the signal for all of them?
Absolutely! The Amplifier kit is designed to support multiple users simultaneously (within the range of the indoor antenna).
