It\nwould be even better if the gain in the straight-down direction could be\nreduced in favor of gain at the edges. Ideally you'd have a constant\npower density over the entire visible earth.\n\nYou could of course use a much more directional antenna on the ground if\nit can track the satellite.\n\n--Phil\n\n\n", "attachments": [] }
