🔍 How each parameter shapes the pattern

📡 Output Power (PT) — transmitter power in dBm. Increases overall radiated strength (brighter lobe).
🔌 Cable & Connector Loss (Lc) — signal loss before the antenna. Higher loss reduces effective power (dimmer pattern).
📶 Antenna Gain (Ga) — directional focus (dBi). Higher gain → narrower, more elongated main lobe; lower gain → broader, isotropic-like coverage.
EIRP (dBm) = PT – Lc + Ga
→ 10 – 40 + 10 = -20 dBm (example)
