Yes! The standard antenna can accept signal from within 170 degrees. If towers are located on the opposite side of your property than your antenna, you may need to upgrade your system by adding a second antenna so you can receive signal from all locations.
We sell high-quality products which are all capable of simultaneously supporting multiple devices. The limit for each booster mainly depends on its output power or ‘dBs’. We have provided a list of devices and their support limit converted to dBs below:
Estimations can also be made using this table:
| Coverage in square metres | Number of supported users |
| Up to 150 sq m | Up to 50 users |

Here’s a simple, quick test to check whether your place is suitable for a signal booster.
The only thing you should do is check your outside signal strength on your mobile phone.
Here’s how to do it:
1. Find the highest point where you could put the outside antenna (generally on the roof).
2. Check how many signal bars you see on your mobile phone’s display while you are at that highest point
3. If you have 0 bars – contact us for help to make sure you’ll get a sufficiently powerful solution.
4. If you are suffering from poor outside signal strength of 1-2 bars, then our powerful booster kit will come to help you to get out of that troublesome situation and provide 5 full constant bars inside. (Of course, you can also use a standard kit with a yagi antenna, but the quantity of bars won’t go higher than 3-4 bars inside.)
5. If your outside signal strength is 3-4 bars, then we recommended you purchase a standard booster kit with a yagi antenna upgrade.
6. In case you have 4-5 bars outside, then no yagi upgrade is required as in this case the standard kit’s power will be sufficient enough to provide you with full 5 bars indoors.
7. Measure your property size to make sure the cable set included in a kit will be enough. We offer extra upgrades to help you have an easy set-up.
This booster is specially designed to work with a poor outdoor signal. We offer a Yagi antenna and more powerful booster included in the kit. The High Power Booster guarantees 5 constant bars inside your property.
You may still upgrade with more internal antennas and extra cable to be able get a signal in all the corners over your home, office or wherever you are using it.
Thank you

I am keen to boost the incoming Vodafone signal into my sterile narrowboat ( all usual problems of a Faraday cage!!) Thus I have ONLY a good 12vDC supply!? What is the input volts/amps to any device. Naturally I do not have a WIRELESS signal just the regular Vodafone cellular signal blocked by the hull. What do you recommend?

I have seen on the giffgaff community that signal boosters do not work on giffgaff, is this correct. Also I get a 2 bar 4g signal in areas in my bedroom, could I mount an external antenna in there as I am disabled and can’t climb ladders.
Dear Stuart, Thank you very much for your question. The boosters we have can work on GiffGaff if it has the correct frequency. I will email you now to continue the discussion about the installation of the booster. Regards, Hellen Dupont Sales Specialist
