Collins' Curtain Array
"J. Mc Laughlin" wrote in message ... Dear Tehrasha Darkon and Group: Yes! An additional curtain antenna is seen off to the right of the picture, which somewhat confuses. Additionally, the butterfly is not easy to see on the nearest antenna. Thank you for finding the picture. Now, if the actual antenna people who have been on this group have not been driven off of the group by the theological ramblings about whether angels exist and, if so, how many could fit on the head of a pin, please enlighten this old antenna person who had thought he had seen every practical antenna (including a good many that were not practical - see US patent 1,554,231). What is the function of the groups of seven + butterfly? 73, Mac N8TT -- J. McLaughlin; Michigan, USA Home: Hi Mac, I have not build those monsters but examining the picture, what it looks like: The six towers in circle seem to be support for the reflection screens, with wires stretched between them from top to bottom. In the middle of each section and on the front of the screens is the tower with sets of two broadband arrays, which should allow some vertical beam steering, like a stack of two antennas. So six direction and some vertical beam steering with great F/B thanks to reflector screens. On the right there seems to be the classic curtain array with reflectors. Most of the guys on this group know everything about antennas, lossless lines, just don't have much in their backyards. :-) |
