FWIW as I don't have that LNB holder, but I can see both possible advantages and disadvantages with that design:
- Advantages: the flat bar appears to support the LNBs very well, and to angle the outer ones towards the relevant parts of the dish face.
- Disadvantages: it may be "dish specfic" due to the way the LNBs are angled, and you probably can't manually adjust the angles by simply bending the bar like you can with the flat bar types mentioned earlier; the LNB clamps look quite wide and that could prevent adjacent LNBs being placed very close to each other, whereas with the other type, the clamps are not as wide and you could actually bolt adjacent ones to opposite faces of the bar so as to slightly "stagger" them a bit closer together.
