Wavelengths covered by Ptarmigan Triffid Dipole Array used at LRO
Admin
That helps a lot — Ptarmigan Triffid immediately explains the confusion 👍 You have not used the wrong antenna, only the wrong band name. Ptarmigan & Triffid (UK Army) The…
Show field patterns at 1420 MHz, derive wave impedance vs frequency, explain why feed probes behave oddly near cutoff, and compare WR-650 vs WR-770 specifically for H-line work.
Excellent — I’ll go through all four, keeping it practical and tied to 1420.405 MHz H-line work with WR-650. 1. Field patterns in WR-650 at 1420 MHz For the dominant…
Why do some websites describe WR-650 waveguides as being for frequencies higher than 1420 MHz? Give equations in ASCII format.
Short answer: because different people are talking about different operating regions of the same waveguide, and some descriptions quietly assume single-mode, low-loss, well-matched operation rather than mere propagation. Here’s the…
Confusion between WR-65 and WR-650 rectangular waveguides
Here’s the clarification you need: ✅ WR-650 is a real, standard rectangular waveguide ❌ WR-65 is not a standard rectangular waveguide designation How the naming works So the confusion boils…
What does the 650 in WR650 waveguide name stand for?
WR-650 is the ideal rectangular waveguide for hydrogen line work. WR stands for Waveguide, Rectangular, and the number refers to the internal broad-wall dimension in hundredths of an inch. Specifically:…
Converting a Python GNU Radio block into C++
Converting a Python GNU Radio block into C++ is very doable, but it’s not a mechanical translation — you’re moving from a runtime-defined block to a compiled, typed one that…
Is there a way of outputting a choice of text on screen dependent on the value of a variable in GNU Radio?
Yes — there are several ways to show text on screen in GNU Radio based on the value of a variable, and the best method depends on where the variable…
Can an effective hydrogen line cantenna be 3D-printed by painting conductive paint on plastic printing material with or without copper infusion?
Conductive paint on a plastic cantenna without copper infusion in the plastic printing material: Short answer: usually no — conductive paint on a plastic cantenna is very unlikely to give…
