If you did not insulate the antenna wire from the fiberglas pole, you may be using a longer radiator than you think! Most of these poles have enough graphite to be conductive to some extent at RF. I use a long rubber band (about 9-12") and a snap swivel to attach the antenna to my 20' crappie poles. Seems to work just fine. Good luck! 72, Lonnie Juli NY2LJ
