40-195/200/201 Rotating Antenna Label
#12

Yes, note the relatively short and lower impedance whip antennas used on automobiles which work quite well. The electrostatic shielded loop antenna did offer some advantages with existing designs at the time. Circuit improvements such as lower noise mixer and RF stages combine to permit better reception of lower level signals. I note that I.F. stages reduced from two to only one. The R.F. stage even in this set only has the grid circuit tuned by variable capacitance while older sets had both grid and plate circuits tuned. Of course the All-American-Five designs essentially did away with a separate R.F. stage and achieved fairly decent reception for the majority of people who lived in cities. There was less interest in shortwave reception after the war and since it cost more to build, most manufacturers quit offering sets that would tune them in.

Did any of the 1939 models have this electrostatic shielded antenna design?
