IF coax length is a hangup then you can use a two to one balun.

Much better idea...


Not really. Insertion loss of a [ferrite] balun could negate any gain
you may get by impedance matching. It is also fixed, while a coax stub
can be easily 'retuned' by simply pinning the coax. Not only that,
since the antenna is (hopefully) way up in the air, the coax used for
matching is either incorporated in the line or hung from the side,
making any worries about extra coax "kicking around" a non-issue. You
should be more worried about where you're going to put that nine
square feet of ground plane.
