Mk3 or Mk 4 LNB?

[eveares]

I need to replace a single channel LNB for a relative as they have a Freesat PVR box with only 1 feed from a single LNB. Dish was installed around 2010 with a new TV they got back then.

Looks like similar to a MK3 LNB to me, but just want your guys opinion on whether it is a Mk3 or Mk4 LNB or something entirely different. What dual or quad channel LNB would fit the dish?

Have a look at Satcure

www.satcure.co.uk/

I've always found them to be exceptionally helpful with questions of this ilk.

It's all explained on this page: http://www.satcure.co.uk/accs/quad_sky_lnb.htm
(There are similar pages for the Sky single-output and Octo LNBs.)

But the question is what if it is not a sky dish at all and something non standard.

 

[Sam Gangee]

No that wasn't the question and the photos clearly show a Sky minidish. I can't quite make out the detail but the arm looks like an open "C" construction, which makes it a MK4.

If you look at the web page (I provided the link) it gives you the relevant details and dimensions so you can check for yourself. Let's not try to guess from photos.

Update, it was a MK4 mini dish with the single Thomson branded LNB slotting inside the arm. Model/Part number of the old LNB was 13553.

You can't "slot" something inside the C-section arm channel unless you bodge it. The MK4 LNB sits over the arm - saddle fashion.
See the page that I linked to.

The MK4 LNB sits over the arm

I know and it does. It was the old single LNB what slotted inside the arm that had a screw and a nut through it.
