It is pretty easy to make a 100 ohm to 50 ohm balanced to unbalanced
transformer system that will work from 14 to 30 MHz. Then feed all 3 bands
from this one transformer system using a single feedline.

You can nest the loops. Loop circumference is 1005/freq in MHz. Feed each
loop by placing an electrical 1/4 wave of 75 ohm coax between the loop and
the 50 ohm coax. A remote antenna switch can be convenient also.

Can feed all 3 wires at the same time like a triband yagi or do I need to
switch them?
