Wave Frontier Toroidal T-90 Satellite Dish

[jerryt]

2 degree spacing on the T90, as promised.

From the end of LNB rail 89, 91, 93, 95, and 97. (ran out of spare LNBs)

95 and 97 are not the correct type LNBs, there are just to show the spacing.

Note the LNB holder view from the top!!! There just is not any room for the holders on each LNB.

Scanning now, this is very exciting!!!!!

View of the side, showing the amount of material removed from the covers.

Sweet job!

So it looks like you gutted the LNB cover and then shaved off part of the plastic around the eye...how much did you have to shave off there?

Might have to try that. My only issue is in the middle of the arc there is no room to fit a LNB in (which for me is 93 middle, 89, 97). I'm not worried about 95 or 99 but I would like to do
83/85 (which I can do right now)
87/89
101/103 (which I'm working on still

Great job

I will definitively try that.


Will post my results also.

I should have tought about that myself.

Again congratulations.

This allows us to really use the t-90 at its full possibilities

by the way..what LNB's are those?

Three Q-Sat brand 88-1018 Reverse Polarity and Three Megasat brand MS1075 Standard Linear

SatelliteGuys has some of the smartest members ANYWHERE!

Good job!

 

[Mr Tony]

Jerry did you have to shave any of the metal off the LNB?

Do you get decent signal results?

 

[Sadoun]

Good job jerryt.

Yes, Shaved the "Horn" to a width of 2 inches.

I am scanning with my Skystar2 2.3 now. &%$# Twinhan does not want to tune, but found a few channel on 89 and 93. Had 91 before the experiment.

 

[Mr Tony]

89 should have a couple news channels
93 is loaded with news feeds

I have to figure out how to shoehorn 91 in between 93 & 89

Exactly, that is what it is SHOEHORNING!!

 

[Mr Tony]

I'll have to try that this weekend

I might have a solution to your "shoehorning" challenge.
Look at our website's "Bargains" section at
www.global-cm.net/bargains.html
You will see a picture with two views of a P-870 stacked Ku LNBF, made for the VOOM system. The feed side is very narrow; much more than the converter side of the LNBF, but my experience has been that the limiting factor on most LNBFs has been the width of the feed end. Perhaps one of these P-870 units can allow you to squeeze in to a tight space, with a little creativity.

Can not get anything on 89 and 93 (Too weak in the 20%)

Maybe they needs some tweaking (up or down? can't go left or right) , or I could try a couple of satellites closer to the center of the dish.

Later after work.

 

[bnaivar]

Damn good job!

I can't help but visualise such a dish at my house as a twisted pile of metal with my blood all over it.

 

[voomvoom]

You guy's are making me think about getting a T-90 dish. I'm jealous!

Much better luck scanning with Mytheatre and Skystar2;

Without any fine tunning of the LNBs
89 = Zero channels (Maybe LOS)
91 = 487
93 = 30 (30% to 45%)

Still need to get 3 or 4 satellites in line with a 2 degree spacing to show that this works.

 

[Mr Tony]

89 has some scrambled stuff and a couple ABC News channels

So I understand that for this to work I will also have to "shave" my lnbs to 2 inch wide, is that correct ?

I will try that this weekend. I also taught about something to adjust them also.

Will keep you updated.

Used a belt sander, without the plastic LNB cover, only the horn cover is 2.5 inches wide.

The side picture shows how much of the horn cover was removed. There is a metal lip for the cover to catch and that is sanded down flush on the sides.

Not impressed with the results so far, may have to align the LNBs somehow. Hoping that this works better near the center of the dish.
