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.

The eye sees an FPV seconds before impact. The radio spectrum sees it much earlier — the moment the video transmitter switches on. Why spectrum reconnaissance became its own discipline, and what intercepted video actually gives the operator.
