From Marcus D. Leech: Probe placement with regards to the distance from the back-short, probe length, and positioning of the waveguide at the proper dish<>feed spacing. That is, if you…
This analysis is for a friend who has made this upgrade. The largest diameter dish we are currently using at LRO is 150cm dish made of 6 petals – soon…
The **P-ESA antenna**, or **Planar Electrically Steered Array antenna**, is a type of antenna that allows for adaptive beamforming and scanning over a wide range of angles. This design is…
Some (not so great)evidence of Leonids detected at LRO on 143.050MHz, Graves. See increased intensity in early hours of 18/11/2025. However, this is nothing like the intensity of meteors in…
Good question. It depends a lot on the material (steel, aluminum, mesh vs solid) and how the “160 cm” is constructed. But here are some reference points + example: 🔍…

Can you recommend calibration noise sources and how would I use these with block diagrams? Nice — below I’ll give: 1) Which noise source to get (practical options) Quick buying…
I would like to buy a 50 ohm terminal load to produce reference samples for 1420 MHz radio astronomy. Am I better off buying one designed for high wattage transmission…
Short answer: yes — but almost never as a single consumer LNA product.Two common approaches are used in practice: Details, tradeoffs and concrete parts: Why you don’t usually see “LNA…
