You are trusting that each radial will be resonant on only one band
akin to a fan vertical antenna. What may happen, for instance, is that
the 40m radial may accept an appreciable amount of energy on 15m and
direct the 15m signal up at a high take-off-angle - less than optimal
for 15m operation. Other interactions are possible, e.g. 28MHz/4MHz=7,
18.14MHz/3.6MHz=5, etc. Any vertical radial resonant at 3/4WL, 5/4WL,
7/4WL, etc. will have a suboptimal effect on the take-off-angle.

I never considered this Cecil. Would you think it better to use a wire trap dipole instead of the Hustler 4BTV
and hang it vertical in the tree ?
