Okay. I collected the Godar antenna from post office today.
I am happy for the buy. Surprisingly I found attached all the rare pieces of connectors and a small transformer from 75 ohms to 300 ohms etc. The cord is attached with (is it F-type) the threaded connector (which I did seek for the Naka of my son!) and an additional adapter F-type to normal coaxial push in (this for the Nak!).
First connected to modded Yamaha CT-V1 300 ohm input with the transformer and two cables to connectors.
Sounded good.
Then took the t-former out and used the adaptor directly to the 75 ohm coaxial input.
Sounded good again.
Yamaha gives only 4-5 stations in stereo. Then another 5-6 in mono. This did not change from my small electronic antenna.
But the sound changed. Quite surprisingly the small bass boost Yamaha had diminished clearly. Still the tune is delicious. Treble got less distorted and more clear. Now things are more in coherence.
So I am quite happy for my first day of listening. More when I will get the Kenwood and Sansui tuners as I think my Yamaha got some filtering or adjustment the way stereo receiving need quite strong station. If signal gets weeker, it mutes. Could be re-adjusted here I think but the other tuners will show the difference.
Look here the Godar and on it, the small triangular electronic antenna I used before:
