At the start of his trial, the prosecution described the attack as “nakedly sectarian”.
During a brief pre-sentence hearing earlier this month, a prosecution lawyer told the judge it was clear the intention of the offences was “to cause terror and fear”.
A defence lawyer said the offences were “wholly out of character” with Wilson’s family and working record.
At the sentencing, the judge noted that Wilson had a good working history, was a “family-orientated man” and had sought comfort in the church after the death of his partner.
He also said that Wilson continues to deny the offences and denied having any negative feelings towards the GAA.
The judge said the deliberate use of a explosive device required “organisation and a degree of commitment and determination from the defendant”.
