I have an Arrow II Yagi crossed 7x7 (440 MHz) and dual-band 3x7 \n(144 MHz & 440 MHz). The manufacturer rates them at 10 W max while \nhand-held, but if I mount them, they're rated at 150 W max? I have an \nIC-910H, max 100W on 144 MHz and 75W on 440 MHz.\n\nThere are two scenarios:\n\n1) On a tripod that someone will stand next to, and manually orient.\n\n2) On a tracking telescope mount I have. My other concern here is that \nEMI will interfere with the telescope's on-board computer.\n\nIn each case, how far should I keep away from the antenna? Sadly, they \ndon't publish radiation patterns. If it's manually oriented, I suppose \nI can have a friend run out to it when not transmitting, re-point the \nbeam a bit, then run away before I transmit.\n\nAny suggestions?\n\nTIA,\n\n-- \nRick\n\n", "attachments": [] }
