There is no doubt a CM7777 would help from your plot.
Plus putting the XG91 in parallel with a V/U combo can cause a lot of unwanted patterns.
To really try the XG separately the combo antenna needs to be removed.
Or separated but 5 feet at least. The CM7777 has separate V/U inputs that will help separate the antennas also on UHF. But still too close together the combo can mess up the pattern of the XG because the V/U has UHF resonant elements. 5 feet apart two UHF antennas hardly see each other.
