well, all right !

I think we have a winner.

Let us know how that works out.

I have just got my third T90 i am installing now, i can as previous poster mentioned that the upper brackets is a major design flaw as it puts enormous pressure on the reflector and also the vital parts that are the most important for excellent reflection.

However i have worked all weekend to get the brackets working with no impact on the reflector by adding spacers to the upper two holes and changed the position of the drilled holes in the bracket.


Now the last thing i did was trying the string method to check if the dish is warped, i don't know if this method can be applied on a Toroidal dish?

Anyway by doing the string method i got horrible results with about 1 inch gap between the strings, it seems the upper part and lower part of the reflector is 1 inch higher than the sides.

Hello

Do you think we can get some pictures of this.

About the string method I really don't know if that can be used.

I can't take any picture as the strings will not show, they are too thin.....

You just use fish strings or sewing thread and put one string from North to South, and one string from East to West.

Use tape to attach the end of the strings at the edge of the dish.

Then you watch the cross where the strings meet in the middle of the dish.

If there is a gap between the strings the dish is warped, if the strings lightly touches each other the dish is fine.

However i don't know if this apply to the toroidal.

Here is what i did to the brackets.

So does everyone think this T90 is worth the hassle?

If so where can I pick one of these bad boys up at? Recommendations?

thanks

someone asked for a schematic of my setup...here is the best I can do

OK...here is a really bad paint program of the setup below so I'll try to describe it.

4 dishes outside. 30" motorized, 36" dish at G10/119, 6 foot C-Band dish at 99 and the T90 with LNB's at 72,74,79,85,87,89,91,93,97,99,101,107,110

3x4 multiswitches on 123 & 99. 99 is H only due to using an old LNB that gets one polarity at a time

Coolsat 5000 runs the motorized. There is a dual KU and a DBS LNB up there.

Coolsat 8000 has a feed from the motorized, 123, 99 C-Band and 87 (since it can decode AC-3 through the box)

Dish 811 has 119 & 110

Starchoice has 107

4DTV 905 has 99

Viacast 2000 has 123 & 99 C-Band. The box is simple (10 tp entry max) so it's limited on what I can get

Pansat 1500 has 8 LNB's via 2 4x1 diseqc switches and a ecoda 22k switch (which can pass diseqc commands). 8 LNB's are 72,74,79,85,89,91,93,97

Visionsat also has 8 LNB's via 2 4x1 diseqc switches and a ecoda 22k switch. 8 LNB's are 74,85,93,97,101,119,123,99 C-Band. Since I can only blind scan on port 1 of diseqc switches (known issue) 74 & 85 are on ports 1.

so there ya go....schematic current as of...oh right now (it could change in 10 minutes)

This also shows some of the squished LNB's for 2 degree spacing
