Hey Thadood,
Interesting idea .
As for "less than ideal " antennas - I suppose they are better than nothing and would depend on how far you are from the Transmitter.
Almost no one uses CB's anymore . I never had one with NWR built in , so I can't vouch for how well they worked - that was a function that probably came out a LONG time after I dumped my CB.
But obviously there is a second NWR receiver board in the CB, so not sure if the boards themselves stunk or if it was ( again) using the "wrong" antenna.
If I HAD to make the mistake though, I'd rather use a CB antenna for NWR receive , rather than an NWR antenna for CB receive

.
FWIW I rarely listen to NWR now, I have too many other sources and would only use it in a dire /power out situation.
