Congratulations to Kai, KE4PT on his appointment to the ARRL RF Safety Advisory Committee. BTW, Kai wrote (with W4RQ) a very interesting article on the effects of trees on antennas. It appears on the February issue of QST. Read it and then vote at www.arrl.org/cover-plaque-poll as best article of the month. 73, Dave, W4DN Celebrating 55 years as a licensed ARO
