Question on antennas for 1930s radios

[Electronic M]

If the radio don't have it's own loop or one shown on the schematic (possibly meaning yours is missing), then it was meant for a long wire. 50'-150' between your building and a tree will work well...Another option would be to string the longwire in the attic (if you have a metal roof and or siding reception won't be worth a crap indoors no matter what you do).

I've had some luck hooking 40's loops to sets meant for longwire ants, but performance will not be close to what the set was meant to do.
