SatelliteAV developed an LNBF bracket that is designed for 4-degree spacing. They have a banner ad here so click on it when you see it when you're ready to check it out (and help make Satelliteguys.us some money). The engineers discuss its design elsewhere in this forum.
The unit only works with the special Geosatpro mini-LNBF's where the entire body is the same size as the throat width. It looks snazzy, too, and the entire bracket moves for skew.
Unfortunately it's not compatible with my two Winegards, as with most brackets they seem to be made for Geosatpro and Fortec Star feed arms, Azure Shine, etc, because the specific angle of the LNBF mount is off by about 8 degrees. I bought the satellite ministry dual-satellite dealer setup that includes the 90cm Geosatpro (nee Azure Shine), the LNBF bracket, two LNBFs, switchbox, and cables. If you already have a Geosatpro or Fortec dish you can just get the bracket and two LNBFs (and switchbox if you need it--the switchbox is also the tiniest I've ever seen).
The installation is very clean--the LNBFs are the tiniest I have ever seen. I haven't bothered to try other LNBFs with the bracket, I don't think the regular Bullet Geosatpro fits, just the new
: super-mini Bullet style.
I should also mention that the super-mini LNBF also comes in a Universal version.
