Matthew Wilson (Letters, December 10) suggests I should research Tetra masts more and claims they don't pulse.

Mr Wilson obviously believes the pro-mast information put out by those with a commercial interest in installing them and not that from those who have taken readings from them.

For the installers to claim that the ups and downs of the signal is not pulsing but "non-continuous modulation" is surely economical with the truth.

Can I refer Mr Wilson to Mast Sanity web site?
