OK..."IT could be" to tune the antenna, you cut a little off that wire until SWR gets to where you want it...sort of like trimming a stinger on other antennas.
If you have a in-line SWR meter, check and see if SWR on channel 1 is higher or lower than channel 40...
IF SWR is HIGHER on channel 40, than channel 1, then your antenna is too long...
IF that's the case, then cut a little off that wire and see if it changes SWR...If it helped lower the SWR any, then you may try cutting a little more off and see what happens. (may have to pull some more wire out from inside the jacket)
