LNB for an Oval shape satellite dish

[ECruzBUD]

Hi folks,

I would like to know what brand makes for an LNB for the
22.5 in. x 32.5 in. oval shape solid satellite dish.

The one LNB that came in with it is a "SWIM" brand,
model sl3s4NR2-02. It's for DirectTV.

What type of LNB to receive DVBS-2 HD Digital with
this oval shape satellite dish???

Thanks.
