MR74 has built in antenna?

[BrandonS]

I am installing two MR74s and I only ordered two ANT-27s.  I plan to get two more ANT-27 so I can point coverage for both bands from the top of a two story building out across an open outdoor area.  

My question is about mounting the MR74 itself.  Should I bother facing it out toward the desired coverage area or just worry about the antennas?

Thanks in advance.

@BrandonS I cannto see anything in the datasheet or anywhere else about an internal antenna. I haven't used one of these so not 100% sure sorry.

Just worry about the antennas.

Makes sense, thanks.  I'll just put the radio on the same pole below the antenna.
