It is not "ludacrous". Sure you can receive with a small yagi or panel or heck, even a set of rabbit ears. It's the uplink that will be the major issue. If you are using small cells for coverage you can probably get away with "smaller" antennas on the towers, but this will limit your uplink capability if you are wanting a desktop type CPE or even a small roof mount antenna. Small cell coverage like with uW freqs will have to be carefully planned due to the propagation characteristics and the potential for self interfernece on such a narrow band. It's not impossible, just more complicated.
