Yaxley-Lennon, who was also known as Tommy Robinson, was born and raised in Luton where the EDL started.
St Albans Crown Court heard Yaxley-Lennon had admitted two charges.
EDL members were among those who clashed with radical Islamists in Luton when they disrupted a homecoming march by the Royal Anglian Regiment in 2009.
