ku Orthomode Feed Assembly question

[Bongu]

Tron,
I would go for 2 at that price plus shipping. I don't mind paypal and paying gift.

 

[phlatwound]

Are there 17 people here willing to buy one? Or fewer willing to buy more than one?

I'd keep 3 of them and sell the rest ...

I would go for 2 for sure, and possibly 3 if it would help the deal go down.

Why doesn't somebody just contact him through Ebays contact system, and ask if he'll sell these singly? I've done that before to other people that have set up auctions for larger amounts, and it's worked for me.

Sounds to me like he has all sorts of them available, and he can set up private "buy it now" auctions and send the link.

Way ahead of 'ya. I just bought mine. There's plenty more available!

Thanks everyone for your help on this. As Panavision mentioned, the seller has relisted them:

If you do buy one, please report back after you have it configured and let us know how it worked out for you.

Since it seems like the OP's question has been, or will soon be answered, I'd like to ask about switches for this OMT setup. I've been reading Anole's tutorial on switches, but I cannot find (nor am I smart enough to extrapolate from his great examples) what I need to get this working. It sounds like a 2x4 switch is what you'd need if you just had the OMT and 1 receiver. My setup has a few added complexities...

I have:
1 Geosatpro PLL Standard Ku LNBF
1 Invacom Universal Ku LNBF (I only use the 11600 LO, if this makes a difference)
and soon, I'll be adding 2 Norsat Ku LNBs (for the OMT)

I want to be able to watch these on my MicroHD.

I already have a 4-way diseqc switch because I currently have an LNB for the 1.2m. It sounds like a 2x4 switch is what I need for the Norsats. I've read that I'll need a power inserter for the vertical side of things. Won't the voltage from the receiver plus the power inserter's added voltage damage the LNB?

Also, does the fact that I have a Universal LNBF complicate things?

Let me know if I need to provide more info.
Thanks for the help!

The powered switch does not use the power from the receiver to power the LNBs. It only senses the voltage from the receiver to determine the polarity. A recent thread about wiring an orthomode feed.. http://www.satelliteguys.us/threads/294721-Wiring-diagram-for-Chaparral-Bulleye-II

Just ordered 2 for myself also. Looking forward to modding a multiswitch for this one. It will greatly simplify my installation.

I hope the 33deg horn will illuminate my 1.8 prodelin a little better than my 51deg one.

 

[Panavision]

Thanks, Magic Static! I saw that thread yesterday. The debate on how to power my LNBs continues. Do I go with a nice, ready to use power inserter, but have to shell out much more money? Or do I face the scary prospect of modding an inexpensive multiswitch I find on ebay? I can solder, it just might not be pretty. Yikes! As far as the feed horn, Bongu, I hope it illuminates my 1.2m. If not, my plan is to bolt the OMT to my existing Channel Master feed horn. After all, the OMT is really what I'm after!

All this talk and I don't think the OMT has even shipped!

 

[Panavision]

Magic, would this resistor be what is needed to mod the WNC multiswitch? I'd like to just hop over to RS, but couldn't find 562? resistors there.

Or can it be some other, more easily available resistor that I might have a better chance of finding at a place like RS? Would this one work?

Please forgive my lack of electronic know-how.
Thanks!

 

[Magic Static]

Yea, I don't know where he got those 562 ohm resistiors. I used the ones in the RATSHACK link 560ohm 1/2watt. Close enough for our purpose.
I bought 3 of those switches for $8 each on EBAY. One for both dishes I have and a spare.

 

[phlatwound]

Just ordered 2 for myself also...

Was the seller able to combine shipping for 2 units, or was it just full price x 2?

Also, there is a new acronym(?) for me in this thread...what is "OMT"?

 

[KE4EST]

OMT = Orthomode transducer

Great. That'll be nice to go to the store and pick these up.

As for OMT, it stands for Orthomode Transducer. It basically separates out the V pol from the H pol so that two dedicated LNBs can be used. It's also used for equipment that transmits. Typically you transmit and receive on polarities that are 90 degrees apart, or orthogonal.

I used the 560 ohm resistors from Radio Shack. They work just fine, and are very cheap for a pack with spares.

Thanks, that was a new one on me.

Your like me learn something new every day....sometimes more than one thing..

You got that right...after reading that wiki article you linked I now also know what VSAT and BUC stand for.

 

[wallyhts]

I wonder if this is the same feedhorn on a starband dish?
