Ashraf Islam, 31, thought the royal had "a moral guilt" because he was a member of the Armed Forces.
Judge Richard McGregor-Johnson said he would not go over details of the plot, but said Islam had "given the matter considerable thought".
Islam, of no fixed address but who had been living in west London, pleaded guilty to threatening to kill Harry.
Defence counsel Roxanne Morrell said Islam handed himself in to police and volunteered the information about the plot.
Ms Morrell also said her client - who was previously convicted for dishonesty and involvement in an attempted robbery - had a personality disorder.
The judge told Isleworth Crown Court in London that Islam's plot was "vague and unlikely to succeed", but said he presented a risk to the public.
"I accept that there is nothing here that could be described as professional plans as to your expressed intentions," he said.
Judge McGregor-Johnson also said he had considered a longer sentence.
"But the authorities are clear, even if a court finds that the person does represent a danger to the public, that doesn't justify a longer sentence," he said.
