An omnidirectional antenna receives from every direction without aiming. How to pick the band, connector and weight for SDR monitoring — across three models.
What a radiation pattern shows — main lobe, side lobes and nulls — and how its shape drives your choice of antenna for FPV and SDR.
When a log-periodic antenna suits SDR and FPV, what directionality and the 530–6000 MHz band buy you, and what to watch when mounting it.
When 360° coverage beats gain: how to read an omnidirectional pattern, where 8.8 dBi comes from, and what actually decides link quality.
A step-by-step guide to connecting an external antenna via an RP-SMA Male connector to improve 4G signal: choosing a 50-ohm cable, reverse polarity, 2×2 MIMO, antenna orientation and checking RSRP/SINR.
A comparison of narrowband antennas and Log Periodic Dipole Antennas (LPDAs): choosing the right antenna based on whether you need peak efficiency at a narrow frequency or stable performance across a wide spectrum.
Open firmware OpenIPC made digital FPV affordable: HD picture, low latency and efficient H.265 on inexpensive hardware. How it works and where it’s used — from civilian tasks to reconnaissance and observation.
A weak FPV signal, noise and image dropouts usually come not from the receiver but from wrong antenna placement. Practical principles: a clear zone around the antenna, vertical polarization, height, the Fresnel zone, spacing from GPS on a UAV, and cooling.
