better way is to house the antenna in an enclosure and mount
it using a support made of PVC electrical conduit pieces [Fig.
5]. This method was useful on a Dish Net parabolic dish to
elevate the position of the antenna. Dish Net dishes have
a chunky LNBF that sits up high so anything you can do to
lift the position of your antenna and make it close to where
LNBF sits will help.

a provision to rotate the antenna 90 degrees [Fig 6]. The
ability to rotate 90 degrees will allow you to match the polarization
of the distant antenna you're connecting to.
