All the transformer will do is change the impedence... What it will not
do is correct reactance... So,if the matchbox is simply beyond its
impedence range the unun 'might' help... But if there is uncompensated
reactance which is almost guaranteed it will not help with that..

matchbox will extend the matching capability of this feedline tuner?
No feedline length changes are possible at this time!!!!!!!!!!!!
