it also requires zero effort on their part
wait, it sounds like you want to use something called four square antenna, but it’s usually only made for HF. you’d have to rework it significantly for microwave region http://tm1o.free.fr/4SQ/80m/en_ver_final4-sq_03_04_15.pdf instead of transformers you’d have to use segments of transmission lines with right impedances and some directional couplers, gives direction immediately, no need to compare phase between different SDRs
Or if you want to get more involved, make a couple of 3el yagis, make a small phased array out of these by plugging them in a directional coupler or 4x4 butler matrix and this will get you two or four receiving directions in a 90 degree segment. If you only want to use that small segment you don’t need a LPDA, regular yagi would be fine
Transformers in antennas are just transformers, but you have to use ceramic cores (ferrites) that would be right for your band. I think that what you might be trying to do would be wideband antenna of some sort, but for UHF which is likely in this case, I’d recommend you some kind of log-periodic antenna instead (it just works, directional) or some kind of spiral antenna (it just works, nondirectional). You can make both of these at home

Depending on local climate, season and proximity to cities or industrial customers, this is often done, but you’ll still have to dump lots of heat in the summer when space heating is off
straight up not feasible for many serious and necessary facilities like powerplants and refineries, unless you prefer very warm lake or river nearby (which also cools down by evaporation later)
19·3日前jesse, what the fuck are you talking about. you can’t make efficient antenna for UHF using power transformer toroid
if valley had fresh ideas for profitable business, they wouldn’t go full into ai in the first place. lol
big brained sfba ceos try to make reality in the image of scifi that they misinterpreted when they watched it 15 years ago, and go around building torment nexii. behold, disruption! (snow crash|ready player one|who knows what else)

I think it would be comparable to situation where all mRNA is suddenly unusable, ie protein synthesis can’t run at all. This would be something like ricin or diphteria toxin poisoning, but instead of being limited to gastrointestinal lining it’s spread all over. I’d guess hours to days before anything visible starts happening (symptoms only start to appear when deficit in new protein synthesis becomes noticeable; all protein already made continues to work for sone time)
in many flats even recently built you don’t get three-phase power, just single phase, but building divides single three-phase supply into three groups of single phase circuits like you say (do you really need 20kW in residential flat? one that doesn’t use EV charger, built in 90s-10s?) i guess it depends on country also. separate houses tend to get three phase connection where i live
floating neutral will also be a problem in american-type two-phase installation, might be even worse (more frequent) on account of large number of lightly maintained transformers used (why on gods green earth there’s few-kV medium voltage line going down every street, americans make it make sense)
Today many of switching mode power supplies accept anywhere between 100-250V
bases of pins are insulated, like in type C/E/F
you don’t have to have three phase circuit to be affected by floating neutral in three-phase substation upstream. in some places in us there are 208v interphase three-phase circuits, which give 120v phase to neutral, which is distributed as a pair of wires as single-phase circuit. this is also normal way to deliver single-phase power in europe, as it’s most efficient use of conductor. (from 400v three-phase circuits) in case more power is needed than single-phase circuit can deliver, three-phase circuit is installed
if there’s switch on device, it’s 2p1t meaning both phase and neutral are switched. if it’s permanent, non-pluggable circuit, like lightning, it’s okay if only phase is switched (neutral is connected permanently)
it’s a bad practice to design appliance in such a way to assume that neutral will have low voltage, because in case of neutral failure in three-phase circuit you can get full voltage there, and there can be a couple of volts difference (sometimes more) between neutral and ground even in normal circumstances
it’s better to cut off both live and neutral at the same time anyway, especially if there’s no standard which is which. also, as device designer you don’t know if it’ll be used on a circuit that has neutral and phase where you think it’ll go or not. (ie british appliance used on unpolarized circuit, like type F. adapters exist)
