Feedback - March, 2004 QST

Clarification: After reading "A Mobile Antenna Base with Internal Capacitive Matching" and "The Doctor is IN" [Feb 2004, pp 43-46 and 65], Alan Applegate, K0BG, reminds us that there's another virtue to inductive, not capacitive, antenna matching. With an inductor shunted to ground, the mobile antenna is dc grounded. DC grounding can reduce static build-up and "grounds" the antenna should it contact any low-hanging power lines.
