This is the TG900P kit we advise for large domestic properties. If the wall panels are fitted whereby the feed cable run up or down within the walls, then the finished job looks very neat indeed
This kit comes with a Yagi aerial upgrade, for when the signal outside is very weak or totally absent, changing the stick antennae for the Yagi antennae can create a signal that will put a smile upon the faces of the building's inhabitants.
The number of internal antennae can be increased but it is important for MobDev to see the building's plans before offering advice.
The TG900PY Kit The TG900PY kit is very suitable for larger houses and buildings where there is very little mobile signal even when walking around outside.
The Yagi aerial is situated at the top of the picture and has a seven meter cable. It can be mounted on the same mast as a television aerial but in a property of this size an aerial contractor will probably install the aerial and an electrician will probably do the rest. The importance of accurately positioning the directional aerial cannot be stressed enough. The whole effectiveness of the installation revolves around the correct fitting and directionality of the external antennae.
You need to find the position of the nearest transmission mast that provides the frequency appropriate to your mobile phone. . One way to do this is to go to www.sitefinder.ofcom.org.uk and this site will help you to find out where the closest suitable mast is located. The possession of a local Ordinance Survey map can often assist in this search. This transmission mast may be several miles away but accurate positioning of the external aerial, can usually achieve good signal strength.
The kit is supplied with two internal panel antennae but this can be increased to as many as six. Two are usually enough for quite a large building. This kit tends to be used when there is negligible signal strength even outside the building.
The elements in the picture are as follows. On the top is the LPDA or Yagi antenna that is highly directional and wants mounting relatively high and well unobstructed. Supplied are three fifteen meter cables. The TG processor unit is blue and is at the bottom of the picture. The Yagi antenna is coupled to this with a seven meter cable and an adaptor, which fastens it to the junction box. The aforementioned junction box is the grey rectangular box with one connection in and two connectors going out. These have a pair of fifteen meter cables connecting to the two panel antennas. When fixing these panels to walls inside the building, take care that none of them point back towards the external antennae
One point to note is that three adaptors are supplied two of which are used to connect the short white cables from the panels to the end of the black fifteen meter cables and the other is used to attach the end of the Yagi cable to the TG unit.
In a three story house the fitting of one of these panels on the ground floor and another on the second floor will usually result in a good signal on all three floors.
Most customers for these more complex kits will use their favourite electrician to install the system. This means that the wiring is kept very tidy. The main TG processor and the junction box are usually situated in the attic. The Stick aerial antennae is plugged into The TG processor where it is marked BTS. This is the end where the on/off switch is located together with the indicator light. The cable leading to the junction box plugs into the main processor unit at the port marked MS.
Ideally try to arrange things so that the TG900 unit is placed just inside an attic hatch with the external aerial socket facing you. This means that when everything is working smoothly and communication suddenly fails, it is easy to check whether the unit is switched on. The only time that this has happened to me is when a fuse had blown due to the same circuit being overloaded by the use of some major power tools.
If your technician has any problems, then call us on 01935 891046 and we will talk them through it. Do bear in mind that all mobile phone users in the building need to be using the same group of providers so as to achieve total connectivity for everyone.
