I tend to be pedantic and I suffer from super OCD, so I tend to include a lot of details in my posts, I am not trying to make it more difficult for you to decide what to do or more complicated.
And others are reading this thread and some may have a situation where saving a dB or 2 or keeping noise out of the signal by dealing with common mode noise ingress issues, may make the difference between a signal that is listenable (maybe not full quieting, no hiss or noise) but is listenable versus not being listenable (to much hiss and noise).
Good luck with your rabbit ear antenna, they work quite will in many situations. I took a quick look at FM Fool for generic Des Moines and it showed a lot of receivable station, but they are located all around the compass and rabbit ear antennas can exhibit some rather sharp nulls in signal reception, so one location, adjustment or orientation may not work equally well for all stations.
Just out of curiosity, what has prompted your desire to improve your antenna situation.
Are the stations, in town or out of town, just weak in signal strength or are they stronger but still with more noise than you would like? Is there distortion that might be the result of multi-path (signal reflection) issues?
Inquiring OCD minds would like to know.
To be clear I mean no disrespect with my little poke of fun about my OCD. I am mostly just like Monk on the old TV series.:yes::yes:
