So far I only have the Wave Frontier T-90 working on T5 with Fortec Star Mercury II.
I have the LNBFs for Dish, but must I configure the 625 receiver to use them? Any help in aiming the LNBFs would be appreciated. The dish is lined up for T5, so I presume the circular LNBFs are in the ball park.

What is it you are trying to do? You seem to be mixing subscription equipment with FTA equipment. Dish's 625 is intended for use with their dishes/LNBs for their subscription service only ... you're not going to get non-DISH broadcasts on a 625. And most of DISH services are scrambled subscription services that you are not going to get with legit FTA.

What are you attempting?

I think he is trying to put Dishnetwork LNBs on a T-90 dish so that he can get FTA and Dish on the same dish. He would probably be able to get more help on another forum.

IF I remember the characteristics of that dish, it reverses the polarity of circular polarized signals, meaning a regular Dish LNB won't work properly with it.

Yeap..... Your correct on the LNB's. He needs to acquire reversed LNB's to make it work. The only ones available for dish are for legacy systems currently....

Yes, I have reversed LNBFs. I've a problem with rain fade. Do the switches for these LNBFs, which have the Dish Network logo on them, require that I configure the receiver?

Well, From the info I've found, you have to use the older switches because they are legacy LNBF's. The newer dish pro switches wont work. I might be wrong so I'll defer to someone more versed on that part.

I was going to do this exact same thing for rain fade and to get to one dish instead of two. I decided it was just to complicated to get it to work with 7 722 recivers. So what I ended up doing was to use a 1000.2 lnbf and a Directv Chanel Master Gainmaster dish I had. The LNBF mounts on the feed arm directly and aligns easily. The 36 inch dish works really good here with very little issues. I still get a bit of fade on 129 at times. Hopefully that will change when the change out the satellite.

You should check also what type of reversed LNBFs you have. Legacy or DishPro ? It would require appropriate switches - legacy or DP/DPP.

Unfortunately no one make a reversed LNBF for dish pro systems. Legacy LNBF's only. Or at least no one fesses up to it.

Sure wish they did. I'd get a T-90 in a heart beat if they did.

 

[P Smith]

It could be done, if Dish or LNBF's manufacturers will open a source of FW what controlling switch matrix.
I did research of the DP LNBFs regarding utilization for T-90/55, but stuck with a mod of FW.

 

[James Long]

Get the stacking and polarity right and let a DP34 or DPP44 do the switching.

 

[P Smith]

Are the any details how to screw stack and polarity of LNBF before switch ? Or it just wishful thinking ?
I know how to use DiSEqC for control LNBF and switch, but screw that ?

Just design something that does the inverse stack. TP1 @ 12.2240 GHz RCP output as 974.00 MHz. TP2 @ 12.23858 GHz LCP output as 2111.42 MHz. Work your way toward the center of the stack (TP31 @ 12.66140 GHz RCP output as 1411.40 MHz and TP32 @ 12.67598 GHz LCP output as 1674.02). A competent electrical engineer would be able to figure it out (as long as it doesn't violate a patent).

Probably not too much demand for it outside of the equipment DISH actually sells. They could be used for MDU installations that would use non-"consumer" dishes.

 

[P Smith]

That's RF engineer job. Not just EE.

I know how the dual LOF LNBF built.
I know what I could do with it - I need a source of FW. There is not a problem to switch polarity - just need to patch FW.

 

[James Long]

As stated earlier, let a DP34 or DPP44 do the switching ... no firmware in the LNB required. Just like the "Feed" LNBs that came with superdishes. All RF.

Unless you're trying to do something else other than just replace the dish with something bigger/better than a stock DISH Network dish (such as connect FTA equipment to DP/DPP switched LNBs and try to control them). But that is far beyond the topic of this thread.

 

[P Smith]

Well, in that case, I'll need switch's FW - not that big difference from twin/triple LNBFs what incorporates same type of DiSEqC switch.

 

[James Long]

Sounds like you have a good project for your spare time that has NOTHING to do with this thread (using a non-standard dish with a DISH Network receiver).

 

[P Smith]

Why? It is exactly what ppl ask.
T-90, Dish LNBFs, need add modded [in FW] DP or DPP switch.
Lets ask OP for clarification.
