About this 3D model

This is an easy support for a circular illumiator for a parable. I have designed it for a my friend because he have need a support witout metal parts. He will use it with a 2.4Ghz antenna and a Mikrotik Accespoint. He has already make a test and he has this results with a wifi bridge long 11Km: rx/tx -53/-61 cqq 100% and 54Mbs (the limit of the AP :-) ) The measures of the illuminator are: -100mm of diameter outside - how long as you wont The parable's tube dimensions are: - 12mm of diameter outside - how long as you wont The parable thet my friend use is 1200 mm of diameter but you can use it for other parable size too P.S.: Sorry for my english
