"Next time there's a similar application we'll do exactly the same."
When the sisters first heard about the proposal they started a petition and set up a public meeting.
Scientist Brian Edgerton gave a talk on what he sees as the health risks associated with mobile phone masts.
Mrs Salzano said: "About 300 people attended the meeting and they went away horrified. We ended up with hundreds of names on the petition."
A few days before the planning meeting, Mr Edgerton, using a radiation level- measuring machine, put it to O2 representatives that their firm already had sufficient coverage in the area.
However, an O2 spokeswoman said: "We need to improve our mobile phone coverage for the area and that's why we need a mobile phone mast so we'll be reviewing other options to try and find an alternative location."
