I ordered a set of monopoles from Value Electronics that should be arriving in the next few days. I haven't found any definitive guidance on how I should orient the monopoles with respect to the AU9. I read on one web site that one monopole should be placed directly behind the dish and the other one should point to the west, but it didn't seem official and I couldn't corroborate that anywhere. Is that appropriate for a rooftop mount? Is there a published recommendation on how they should be placed? Thanks in advance for the help.
