SureCall Ultra on Tesla Model 3
I’m replacing a Fusion2Go 3.0 in this car. I kept my existing upgraded SureCall interior patch antenna with the thicker coax and my existing weBoost Drive Reach shark fin exterior antenna. The outside antenna is mounted near the C-pillar so the body acts as a shield and prevents oscillation. Other mounting spots tested as “Good” in the apps readout, but this position reliably shows “Great,” so that’s where it’s staying. Using my driveway as a consistent test spot and iPhone field test mode (RSRP), the Ultra is a clear upgrade over the Fusion2Go 3.0. With no booster I get about two bars of 5G, the 3.0 gives three to four bars of 5G, and the Ultra gives a solid four bars of 5G+. When I flip the Ultra off, RSRP immediately gets worse (more negative), confirming the gain. I also have a weBoost Drive Reach in my CR‑V. In my experience, the Drive Reach beats the Fusion2Go 3.0, but the Fusion2Go Ultra beats the Drive Reach. That lines up with published specs and marketing that call the Ultra SureCall’s most powerful vehicle booster, with higher uplink power for reaching distant towers. I’m not a pro installer, but with consistent test locations, field test mode, and back-to-back comparisons, the difference isn’t subtle. The Ultra is the best-performing mobile booster I’ve run so far. Note: The screenshot of the antenna isolation graph was taken while standing outside the car, near the unit, so I could connect to it via Bluetooth; therefore, the phone's signal reading is not representative of the signal while sitting in the driver's seat.
