Jswanson, no problem. You can run the antenna in any direction you want with no change in performance. The main thing is that you get a reasonably straight run; i.e. no doubling back. I've often seen them set up in a dogleg fashion with no detectable degradation. By dogleg, I mean that they have a change in direction somewhere along there length but usually less than a 90 degree turn, such as to the fin leading edge then out to the stabalizer tip. On my combat planes I run the antenna down the length of the wing, all inside next to the spar.
