Why do you think the oldtimers used ceramic insulators on both the feedline and
antenna?

If matched and you have low loss feedline , a short dipole radiates just 
fine. But, the antenna systems Q will go up drastically. This high Q is the 
real problem. And just a matter of physics. No way around it.  Along with 
the expensive components in the antenna tuner to accommodate the high 
circulating currents and voltages due the high antenna system Q.  You could 
put inductance at the feed point to nullify the capacitive component of 
the  antenna's impedance but the Q will still be high and it would only be 
useful at only one narrow band of frequencies.
