  • this is just small-ish magloop

    i’ve seen some people make magloops out of bike rims, it’s similar sized. the smaller it is the lower radiation resistance, higher currents and voltage on capacitor, narrower bandwidth, and lower efficiency. i don’t remember how it scales but efficiency goes up fast with size, 1m dia magloop is already better. downside is that tuning becomes impossible on higher bands (capacitance required for this is below minimum capacitance of capacitor that you have)


  • will it antenna? i think it will

    split ring resonator has already two different lengths of paths so - even without accounting on how these two interact - you could expect two different frequencies where it’s resonant, with peaks perhaps overlapping to a useful degree making a decently wide band possible. it looks a bit like halo antenna with parasitic, downside being that it’s probably a bit hard to feed it, circumference has to be halfwave on lowest frequency and if made for HF it’d be gigantic

    i think it’s more useful to think of magloop as extremely shortened, low impedance, low bandwith halo antenna











  • that key to heaven was probably something between mistranslation and bs, but there’s so many more awful shit!

    electric swamp - iraq used swamps as a natural barrier, laying mines, placing mortars and HMGs around, and also putting high voltage wires in water. when iranian raid was detected, they’d just fire a bit until iranians fell to water, then turned power on

    BWR fights - phoenix missiles on iranian tomcats. iraqis had no idea what’s going on to the point that they suspected sabotage (mirages just fell apart in air for no reason)

    war profiteering - lots of countries sold covertly weapons to iraq or to both sides, but swiss were probably worst: they sold gas masks to iran and chemical weapons precursors to iraq

    ww1 era warfare complete with said chemical weapons, and also genocide of Kurds for some reason

    and all for nothing (result: status quo ante bellum)
