What About Using a 9:1 Matching Transformer with a Longwire Antenna and a Ground at the Radio Shack ?

NEIL - The Answer would be : No and Yes ~ RHF Generally Speaking using a 9:1 Matching Transformer with a Longwire Antenna and a Ground at the Radio Shack : [ The so-called "Magnetic Longwire Balun" (MLB) ] 1st - "No" - The peak Signal Levels may be less on some Frequencies -but- the Average Signal Level will be equal or higher across all Frequencies : 500 kHz to 30 MHz. 2nd - "Yes" - The Average Noise Level will be lower across all Frequencies : 500 kHz to 30 MHz. 3rd - "Results" - Good Signal Levels and Lower Noise result in a Better Signal-to-Noise Ratio which means that the general Listenability of your Signals coming from the Antenna to your Radio / Receiver Improves "Significantly".
