I discovered that the cones in my Fresnel Antenna should have been "STACKED" TOWARDS THE lnbf. Also this was not a true FRESNEL LENS antenna, it is a "CONICAL STACKED ANTENNA" A WHOLE NOTHER ANIMAL.

Since I am not able to upload .jpg files anymore I've inserted this link to a websiate that shows more details of a Conical stacked array and a true Fresnel Lens collector.
I find these interesting, but it is likely that they will not work properly with a DVB signal. Possibly due to the concentrated signal not being completely in phase.
Since this, I have made a fiberglass parabolic dish by inflating a six foot diameter balloon and covering a 1.8 meter dia. with fiberglass.
It seems to be a perfect parabola and you can even make an offset dish by applying the glass over a 22 degree slant of the balloon. Weather balloon, the kind some folks here attach to their lawn chairs and go flying. :-worship
The interior surface is as smooth as a babies butt and takes the zinc paint to form a conductive and reflective surface.
I have found a URL that includes a Excel Spreadsheet for making a segmented Parabola from a flat sheet. I will build one to replace the "Conical Stacked Antenna".
This type of antenna has flat petals but can be made more effective by spinning it with an epoxy slurry inside. This is how some Astronomer Hobbiests make their lenses. It should be perfectly accurate and not require a lot of Epoxy because 90 percent of the parabola is already there.
I will make a folded cone antenna by cutting a 45 degree cut through it and rotating it to a 90 degree offset. This should make a cone that is much more managable t
