Detailed Answer
Antenna angle optimization means adjusting the transmitter/receiver antenna angle according to coverage needs for best signal coverage: vertical-polarization antennas radiate horizontally (antenna vertical → coverage in all directions); tilting the antenna adjusts the coverage direction; keep away from metal obstructions. The Leader LD series installation guide provides antenna angle advice: receiver antenna vertical and upward, higher than obstacles.
| Principle | Vertical pol, horizontal radiation |
| Receiver | Antenna vertical & up |
| Avoid | Metal obstructions |
Note:Signal attenuates noticeably when the antenna is near metal beams; keep away from them.
