I recently was comparing the sound of the Magnum dynalab ST2
whip antenna with the Delhi Qfm9.I am able to do this with the simple
turn of an A/B switch on my Dynalab md 106t.This allows quick comparisons of two simultaneous hookups.I do not even have either
of these antennas properly mounted.The St2 is just by the window and the Qfm9 is sitting horizontally on my patio on the barbecue.I have many local stations that easily give a full signal reading with the antennas situated this way.Even so somehow the background noise is
drastically less with the qfm9.Another thing somehow even on stations where there is no noise and I am receiving a good strong signal,when switching to the delhi there is slightly more bass.Like
a whole other octave of sound is there.The music also sounds much less
compressed.There seems to be more dynamic range.I went back and forth
like this and there is no mistaking it.Cymbals also seem more lifelike.A more natural shimmer.With both antennas,I have a full reading on my signal strenght meter and yet the sound is better.
I would never have guessed that the antenna could make this much
difference strictly in the sonics.I always thought the antenna was
just to get a clean hash free signal,but it appears to my ears to be much more important than that.
I have local stations that are less than five miles away with very strong signals that do not even require an antenna to receive.Yet
those stations sound better through the Yagi delhi Qfm.I would urge
anyone who thought they were getting adequate reception with anything
less than a directional Yagi to give one a try.In my case I only had
to sit the thing out on the patio to hear the benefits.I can"t
wait to hear what it will do when I get it properly mounted on the roof.
Follow Ups:
your tuner is probably well into full limiting on the QFM9 but not into overload,High sensitivity and very good overload ought to be feature of a modern expensive tuner.
So until we do hit overload on an 'important' station I take the view that like a jewish mother's chicken soup you may well be benefitting still, and you may find that you can now get more acceptable and good sounding stations.
As a signaller in the infantry, years ago, I rapidly began to take an interest in how resiting or even changing antennas when not on the move, and then too!
Unless I am mistaken,the higher end magnums have a five stage front
end which I thought was to prevent overload of the signal whereas
most high performance tuners of the past were four stages.But I
may be wrong here.
Mind you it helps to have a station worth the trouble, *, doing simply miked OB's / recordings of acoustic classical, and jazz as well as cd's and tapes from overseas incl. the Met!!!!. No ads but lots and lots of promos which are beginning to sound like them, anyway!I've got a second and its less promo-ish and gentler with it, a local community arts / music mob and they do use compression, but not a lot, and they record concerts/OB's, and their ads aren't LOUDDDDD!!!! and they cover lots of music and stuff *Auntie ABC's Classic FM just won't/can't. World, comedy, Blues, etc! guest speakers at events etc.
Thankyou for confirming that -any old antenna will do - isn't a full picture - of the potential sound quality benefits - for good rational and objective ohm's law type reasons.
IMO and E the more directional the better - with sufficient gain for fully limiting all my FM sockets/ rcvrs in the house. etc,
Within reason, but mine's gig was to being directional from ChO VHFTV/11/ to Ch10. Yep that big old LONG Tandy item with <5dbd gain, signal strengths are NOT the problem here, hills ARE.
I may simply restore/clone the dear old thing - or some other longish FM item. At least all the other gear and cable would still work (! less $$$$!?)
And clone / restore the CA8 dual-H / phased array plus CH 2 gain extenders!
Off to the recycling joint!
Projects for summer!

Odds are you're hearing the what the difference in signal strength and multipath rejection can do to improve a signal and how your tuner shows it's gratitude for them.
Yes that may be the case.I did note that my signal strength meter
did not read any difference.Although it I do know that the signal
meter on my Dynalab md106t is designed not to go past a certain level
to prevent damage to the gauge.So yes the signal could have still been stronger.
