Regarding antennas, I also think that in general "bigger is better".
But is there much difference in take off angle (at 136kHz) between a 20m

and a 40m tower?
May be we should not look only at the antenna. How about the
counterpoise and the terrain around the station?
I'm living on a north-west slope of a hill and my short-wave signal from

my beam, 5m above the roof, and the 100W I can put out, produces often a

much better signal in the USA than other Swiss stations with 40m towers
and a KW.
Sometimes I think that this has also an influence on my LF situation,
but I'm not sure. Fact is, that on LF  I can work well to the
north-west, while I have difficulties in other directions.
May be, this is not so important for you "flatlanders", hi, but I could
imagine that the soil and the (non-existing) radials around your antenna

(some kilometers around the antenna!) has also a certain influence on
the take-off angle?

PS. Actually it is very cold here and my antenna de-tunes from hour to
hour as the soil is freezing deeper and deeper. Not only the resonance
goes higher, the impedance is also changing and it is difficult to
follow this developement with the existing matching circuit.
