My Grandfather recently bought a Jesnen 1250 Stereo
https://www.amazon.com/Jensen-JMC125.../dp/B00LP3DCDI
It has a single wire FM antenna.

It gets decent reception, but wants to improve it, specifically channel 89.3.
He bought an FM antenna (link below) but it does not work because of the single wire antenna.

My question is, can I connect the red wire from the antenna to the existing single wire from the stereo and ground the black wire out. If so will it work?
If not, how can I improve the reception on a single wire antenna?
TIA
