JetStream JTB2B Dual Band Antenna Gone Bad

Helping a friend with a Ham Radio antenna problem. The antenna is a JetStream JTB2B Dual Band 2m/70cm 2 section type. It had been up about a year doing fine when he suddenly noticed the SWR was high.
The meter I am using in this video is a Daiwa CN-801V 140-525 mhz 200 watt cross-needle type. The radio used is a Kenwood TM-V71A Dual Band mobile.
