Mark:

I have the "slow build" tail and when I installed the com antenna in the
tail (per instructions), I measured the VSWR over the com frequency ranges.
An antenna movement of a couple inches made a HUGE difference in smoothing
out the VSWR over the com operating frequencies. I would advise that before
you finalize the antenna location, check the VSWR (find  ham operator with a
VSWR meter) on your antenna installation and move it to get the best VSWR.
