hello martin. I also missed your post (dec 20 is my b-day!) yes the LNB is designed to fit on a feedhorn. I've attached norsat & skyware spec sheets for reference. I love sat related hardware so I am biased. I would take them up on the offer. However only you can determine if it suits a need or want of yours.
Contrary to what gilbertini posted ('Im going by model# in pic) the LNB is not a PLL design it is a DRO unit. However the Norsat 4000 series DRO types are quite good just not as stable as a PLL. It is a Norsat so it should be high quality. Please note 2 items on the LNB. Its freq range is LIMITED to 10.95-11.70 GHZ Ku band. Its LO freq is 10.0GHZ.
As for the feedhorn kit it looks like a brand new Skyware Global unit (similar to what I installed on Winston recently). From the pic it looks to be a single polarity C120 waveguide flange. it might come with a c-120 to wr-75 flange adapter to mate with the LNB.
Just be aware that Skyware make different versions of feedhorn. See if you can find out the model or part # of the feedhorn kit. Some are single linear polarity some are dual circular polarity. Some are narrow 11.7-12.2 GHZ Ku band some are wideband. Some Skyware feedhorns only have a C120 circular waveguide opening flange. The Norsat LNB is a WR-75 rectangular waveguide opening flange. So they may not bolt together properly without an adapter plate.
Hi martin. On "Elisha" currently I have a Chaparral dual c-band feedhorn with two norsat model 3220 lnbs (1 for H 1 for V). the norsats are very expensive however .... about 150 GBP each. I took the bullseye2 off simple cause I wasn't watching a lot of ku. I use my fta dish for my main tv viewing so I want the best lnb I can afford. If you look at what lnbs are on a professional Canadian cable tv company's (equivalent to Sky or BT) satellite dishes chances are good its a Norsat. My norsats both need 18V Dc power so I had to modify the internal circuitry of a multiswitch to change the horizontal voltage of 13vdc to 18vdc. You could use a powered multiswtich I think (like a EMP-centauri or a Spaun) but they are very expensive. here are some pics of my feedhorn & a norsat model 3120 lnb (its the next model up from the 3220's I have)Hi Kevin, what setup do you have for C band at the moment please, on any /all dishes also any pictures would be nice as and when you can , I also have a feedhorn for you to take a look at if you would be so kind .
Thanks for the information Dave, what's this talk on losing some C band frequencies in the near future, how long will it be before this is in place ? if i have read it correctly ?, i don't want to be spending £4/500 on something to last 12 months.

Hi moonbase Yes I originally had one of those on my 3m dish. The power inserter is a good commercial grade product. Just a friendly reminder that you will probably need a switch (22k or diseq) to select which lnb output to connect to your receiver.Just a quick question to "beavs2112", did you consider using an inline power inserter such as a PICO MACOM unit to get the 18v required for the Norsat LNB's ?
Martin,
You could go the much cheaper C band route with a Titanium C1W-PLL or Titanium C2W-PLL LNBF, these cost around £30 for the single output (C1W) version and are available from eBay or Amazon. They come with the scalar ring for a prime focus dish and other forum members report good results with them. That saves on the cost of the Chaparral feed and the Norsat LNB's.
I prefer a dual cband feed feedhorn with 2 lnbs. The reason is my dish is 6 feet above my roof. The chaparral polarotor requires wiring to control the polarity motor and if that fails its a PITA to fix. many years ago the polarotor was the only option. but if the polarity motor or one of its wiring connections fails you might get only one polarity or worse none at all. a dual cband feedhorn requires no such wiring. The dual cband is more expensive since you need another lnb & rg6 cable but its more reliable.There are several options for Chaparral feeds, they do a combined C band/Ku band feed with a polarotor for a prime focus dish. However, there seems to be a view that if it is only C band required from a dish then a dual C band feed is the way to go. I think one of the bands is compromised slightly using the C/Ku combi feed, cant remember which one though, perhaps "beavs2112" can add some info on this point?
