Record the serving cell, band, RSRP, RSRQ, SINR, latency and throughput while aiming the antenna at each candidate direction. Repeat tests at similar times and allow the modem to settle after each change. The nearest tower may be blocked, congested or not carry the required carrier bands, while a more distant tower may provide a cleaner path.
Where the router supports band or cell information, use it to confirm that a direction change actually selected a different service. Do not optimise only for download speed; check upload, stability and performance over time. Coverage maps and tower-location tools are useful starting points, not final proof.
Public Q&A
How can testing identify whether a directional antenna is aimed at the most suitable tower rather than simply the nearest one?
