Here are my logs from last night with the very small active powered EWE-ant.
I found the performance is similar than the 10times larger EWE - the missing sensitivity on the small one is compensated by a high impedance pre-amp directly at the feedpoint of the antenna.
2 differences between both antennas, (only when used on 300kHz)
- the F/B ratio on the small antenne is less than with the big one - about 10-12db for the small one, 15-20db on the large one
- the Front/side ratio is bigger on the small antenna - the side signals are about 6db down to the large antenna, while front signals are of same strength
Overall I am very happy with this small EWE-ant. I works as a highly directional antenna up to 15Mhz - above it becomes more and more a broadside, bi-directional pattern 90deg to the horizontal part of the EWE. That can be interesting also, as two deep nulls develope, when increasing the frequency even more...
So it is cetainly not only a great low-frequency antenna, but also works on the high bands.
I compared the mediumwave (broadcast) band with my 170m Beverage antenna as well as with the large EWE.
The small EWE is outperforming the large EWE, because the pattern is much cleaner! Amazing, that it often is very close to the performance of the 170m Beverage antenna
I also used the antenna for listening in last weekend 160m contest - I must say, that there is no big difference to my 170m beverages, which would require that much work to set-up the Beverages every winter and tear them down in spring. Next winter I will skip the Beverages and make 2ele, active fed versions of that small EWE with switchable phasing to steer the pattern by throwing a switch from the radio-room... much more versatile and easier to build-up and maintain...
