Consistent independant test have proven TETRA masts and antennae PULSE. NRPB supported by the Government and of course the Industry consistently claim they don't. They rely on a spurious definition of pulsing to convince people. A pulse is a Pulse ONLY when it drops to absolute zero between peaks. TETRA masts do not ( just above zero) With this definition it also means we do not have a Pulse... Common Sense MUST prevail

Myths about Tetra The Reality

Its LIVE in over half of the Not Entirely true.  To our knowledge no police force (apart from the original Lancashire UK police forces who are having to live with a number of blackspots) is yet using the Tetra system

exclusively.. they are parellel running it alongside  the old analogue system until the police forces in question are happy wth the system.. Its a little unnerving (but not surprising)  that NONE are yet happy with this system to feel confident to change over completely.

Also note the system in Jersey is NOT Airwave (see section at bottom about why that is important)

Tetra has been used in this a few years yes but with only 1000 masts many of them remotely placed, and many of country for years with no them hidden or not known about by the local communities, then its no wonder people problems. have not complained YET.  Every Dolphin/Inquan (the other Tetra system) mast we know

about so far has ill health round it - have they done any health surveys round these masts to find out theres no problems?

The Tetra system that already exists is commercial and used mainly by haulage firms and security firms in localised areas.  We have not yet been approached by any of these users however many will not be aware of what they are using.  Also the nature of this industry may mean there is a high turn over of staff.  See below why Dolphin cannot really be compared  with Airwave.

It doesn't  pulse...  It does...  Chepcick tuouret sthferosem Isle of Wight to see how clear it is

They argue NOW that it doesn't because the pulse down doesn't QUITE reach zero on the downwards pulse, but it does drop and then go up again...  to Quote Alasdair Phillips of Powerwatch " their definition of pulsing denies that we have a blood pressure pulse as the blood pressure does not drop to zero between peaks.."

we need a new system to Okay we agree with this BUT there IS equipment out there that can listen in to Tetra.. I prevent criminals listening wouldn't be able to find it and I wouldn't because its illegal BUT a determined criminal

in will  Also as the encryption codes are with the US govt then in theory they reportedly can

listen in where ever they want as well

Tetra and tetrapol are the NO... the 2 systems are completely different technologies.  Tetrapol has been around for same thing many years now and is proven in a number of national systems across the world. Its a

shame that the Tetrapol system is named in this way as it adds to confusion.

We are not yet aware of health issues relating to the Tetrapol system.  The masts do NOT pulse at all and the system needs significantly less masts than the Airwave system.  For example.  Currently we believe O2 have 20 plus applications for masts in the Isle of Wight.  We understand that the Tetrapol system would only need 3 !!!

Tetra is the name of the Again this often misleads people.  Tetra is the name of a standard NOT the name of a System system.  Our system is called Airwave! So yes there are SMALL SCALE systems across

the world that conform to the Tetra standard but NONE are the same as the Airwave system and NONE are nationwide systems with thousands of users.
