Cloverleaf 5.8G antenna cover (compatible for 90 degree adaptor)

I bought a pair of cloverleaf 5.8G antennas from the shop and found the product itself with cover is more then double. Therefore, I made the pair of the covers for my antenna. Of course, you can make your own one with the following reference.
