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.

Megapixels do not give you range — the lens does. How to work out pixels per metre, when 8 MP pays off, and which specs matter beyond resolution.

When 360° coverage beats gain: how to read an omnidirectional pattern, where 8.8 dBi comes from, and what actually decides link quality.

How to keep video connectivity reliable in the field on dynamic IPs (CGNAT): focus on data-transfer protocols rather than a static network — RTSP/RTSPS, DDNS, VPN tunneling, jump box.

A camera that runs its own stream to a server without a static IP: how it works, who it suits, specifications and the real cost of ownership.
