Back in time, when I worked as radio engineer for incumbent MNO, we had very good experience when using yagi or log-periodic “beasts” for the “low-band” wireless broadband. Such as Iskra P-40 MIMO (for a multi-band variant, look at their antennas with model name P56 or higher).
There are similar offerings from different vendors. Just be sure that vendor publishes decent antenna gain diagrams (relative to frequency) to be sure that antenna does have decent gain at frequencies you’re going to use (single-digit gain figure from specs almost always tells about maximum gain in whole supported frequency range and some antennas are very far from having linear gain over the range). Iskra has them in the catalogue, available for download from their product pages.
And yes, for 4G and beyond you’ll want to use a MIMO bundle, consisting of 2 antennas placed at 90° angle (sometimes they come as “MIMO dual-port antenna” in single case).
