Parabola antenna
WebOct 19, 2024 · Antena parabola membutuhkan pemasangan yang sedikit rumit. Berbeda dengan antena biasa yang bisa langsung Anda pasang pada TV Anda secara langsung … WebThe way a Parabolic works is that it reflects the signal from a larger surface area than that of the antenna alone. Then concentrates it at the focal point. This dish as crude as it may look gives me ~13db gain receiving from the same router it was before.
