It is not an article, so it is early still to write scientific treatises on this subject. It is while a test, supervision, analysis, searching of answers to many questions. My experience can encourage ones, and others I will disappoint. I think, a EH- antenna can compete to any dipole, IV or GP, EH-antenna can work both at a field, and at restricted urban conditions.

More info one can find in the internet:

 Schematic of the antenna is below.

But I have done my own design that you can see on the pictures.

connection. Variable capacitors have max capacity of 55-pF. The cylinders have diameter of 80-mm, height of 200-mm, and made of a bronze sheet of 0,5-mm thickness. Using such antenna details, it was possible to cover a frequency range from 10 up to 30 MHz.

If you have not such variometer, you can try to tune the antenna to separately ranges. For example, for 20 meters: L1=10 coils (3-microH), copper wire of diameter of 1.81-mm (#13 AWG), dia 30 mm, L2=16 coils (6-microH)
