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)
