Question about Goobay 80 cm aluminum satellite mirror

To find a suitable multifeed holder for two LNBs that fits your satellite dish, you should look for a model that can be used universally and can be adjusted to different satellite distances. Some options are multi-feed holders that are suitable for different satellite distances, such as the universal multi-feed holder with adjustable LNB mounts, which allows up to 12.5° spacing. Another approach would be to look for a model specifically designed for your antenna array or similar models. As I don't have any specific information about compatibility with Goobay products, it would be advisable to ask the manufacturer directly or search for experience reports in forums.
