I'm sure it will play well in terms of keeping your transmitter happy but
the relatively large bandwidth you are measuring is indicative of
substantial loss in the system somewhere.
This would be a large bandwidth even if you did not have the bandwidth
narrowing effects of a shunt feed.

Hi guys, the 3 wires is actually a transmission line and the antenna is well
known as Folded Unipole with 200 ohms impedance. My antenna is a Folded
Unipole as well and has the same broadband SWR measurement's. The loss is
the same for any tuning circuit it has nothing to do with the bandwidth. The
ground plane does, and in this case it is the same, right?
