Illuminator support for parable 100mm

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
