Here’s a comparison of typical power consumption (no peripherals or display) for each device, measured at the wall under different workloads. Device Idle Power Moderate Load (e.g. data logging, web,…
A Kumar choke (often called the VE4MA or Kumar feed/choke) is a choke-ring / cavity around a horn/feed that suppresses unwanted surface and coaxial currents and “traps” or reflects energy…
Short answer: No—the dish doesn’t change the waveguide dimensions of the cantenna.The can’s internal diameter and the probe/back-short geometry are set by your operating frequency and waveguide mode, not by…
