Recently I have repeated these experiments to find
the top frequency of the discharge generation. I switched on in
the circuit of a discharge needle, (also I have tried a small
broom made from thin wires) different LC- circuits. It was easy
to obtain generation at 1-MHz. But I managed to get generation
up to 5-MHz. However, I believe it is possible to get generation
above 5-MHz.
The Broom Antenna was tested with a detector receiver. This receiver
with a LW antenna (12- meters, 45 degree above the ground) provided
1.5-V across a high-ohmic phones (day time, broadcasting Russian
radio station Mayak, 549 kHz, the station was located at 28-km
from my Broom Antenna). Vertical Broom Antenna (that was described
above) provided 4.5-V across the high-ohmic phones. I do not insist
that it was caused by "amplification" of the Broom Antenna,
but... No any fluctuations at receiving were detected with the
Broom Antenna.

To prove the efficiency of the Broom Antenna more experimenters
are needed to do. Very useful would be experimenters with receiving
very weak signals- nano and pico- Watts
in power. However it needs to use at the experimenters receivers
with high-resistance antenna input because the Broom Antenna has
extremely high output resistance- may be Giga and ever Tera- Ohm.
Be Careful! Experimenters with high-ohmic
antennas that may do ionization of the air are extremely dangerous
at any (and especially at storm) weather. Any experimenters with
the Broom Antenna you are doing at your own risk!
