I have the Maxview Semitronic fitted on the roof but carry a tripod and small dish just in case something is in the way of the roof one
So far in 5+ years its only been used once but you do need to pick a suitable pitch when possible as with all satellite systems
To answer the question I considered removing the pole mounted Status aerial and replacing it with the dish but the dish would have been too near the van side and would have protruded
This pic shows the dish just in front of the adjacent tree !!
