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".
