Kevin Barry Concannon, 41, from Beechwood Avenue, was sentenced to eight years with half to be spent in custody and half on licence.
Concannon admitted having photographs of the headquarters of Merseyside Police in Liverpool. He had pleaded guilty in June this year at Belfast Crown Court to a total of seven offences.
The father-of-one also admitted possessing an explosive substance with intent to endanger life or cause serious injury to property.
He entered the same plea on a similar charge of possessing explosive substances - aluminium granules, magnesium ribbon and metal springs - with intent to endanger life or cause serious injury to property.
Concannon also pleaded guilty to possession of a deactivated sub-machine gun, a set of number plates, smoke canisters and a thunder flash.
He also admitted a charge connected to having images of Merseyside Police HQ.
Concannon's wife Lesley, a fitness instructor from West Virginia, was originally charged with her husband over the explosives haul but the charges were later dropped.
Following his release, Concannon will also be subject to a counter terrorism notification period of 10 years in which he will have to inform the police of his address and movements.
