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.
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.
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.
A detailed comparison of infrared (IR) versus full-color night vision technologies, helping you choose the right camera based on your priority: maximum range or colour identification.
