| Environment | Antenna Type | Gain | Polarization | Expected Gain | |-------------|--------------|------|--------------|----------------| | Urban canyon | Panel (directional) | 8 dBi | Cross-pol (45°/45°) | 6-8 dB SINR improvement | | Rural, trees | Omni (collinear) | 5 dBi | Vertical | Prevents deep fading | | Maritime | High-gain Yagi | 12 dBi | Vertical | +12 dB but narrow beam (25°) |
| Metric | Threshold for Usable | Optimization Action | |--------|----------------------|----------------------| | (Signal Quality) | > -12 dB | Point antenna away from noise sources (inverters, solar controllers) | | SINR (Signal to Noise) | > 5 dB | Increase antenna elevation by 3m or switch to lower gain, wider beam antenna | | RRC State | Connected | If ‘Idle’, set AT+CFUN=1 to reset radio | invisagig modem
Using a high-gain antenna (>10 dBi) without a low-noise amplifier (LNA) can overload the modem’s front end, causing intermodulation distortion. The InvisaGig’s maximum input is -10 dBm. 6. Bonding Configuration (Speedify / OpenMPTCProuter) The InvisaGig can bond cellular + Starlink + DSL via its second Ethernet port. | Environment | Antenna Type | Gain |
