Its not so much for heating reason. try resonating 100 ohm inductor at 12 volts ,it won't get hot but it will not resonate very well either. It all has to do with conservation of energy. if you have 5000 watts in the primary you will only get 5000 true watts in the secondary.lets say you secondary reactance is 45k. remember i^2*r. secondary with 50 ohm will reach 10 amps at 450 kv. secondary with 100 ohms will reach 7 amps at 315 kv. Thats why bigger secondaries generally have higher voltages. but this is dc ohms , you will have radiation loss,skin resistance, and proximty loss. on a quarter wave coil , best case scenario lose 36 ohms to radiation loss even with 1 ohm dc resistance
