The pink building seems to provide the clearest view around the curve of the street. Line of sight is very important.

As far as antennas go, check the arc of coverage (azimuth) to make sure it covers the width of the street, and get the highest dB you can afford, legally and monetarily. Make sure they're easily adjustable for aiming.

You can always try a repeater later, after you get the main service up, just to see how well it does.
