It was a lots deal to do at that day (when I made the
antenna), so at last I just measured the antenna parameters but
not tested the antenna in the Air. Figure 6 shows the parameters of the EH- Antenna.
The antenna has band- pass in 930-kHz (at SWR less the 2).
Near the antenna was installed RF- Choke- several turns
of coaxial cable around of a ferrite ring. The choke is visible
on the Figure 5.
The next day a rain was coming. Water dropped from
the antenna and I thought that no chance the antenna alive. Figure 7 shows the antenna into
I turned on the EH-Antenna instead of my 42- meters
wire… Noise (compare to 42-m- LW, the antenna installed from another
side of my home) dropped down but stations went up. First QSO
was with UA0AV, Sergey, Krasnoyarsk-
599. Next ones- M0IOW, RK4HE, SP3OOC and VK3XQ, Australia, my rapport 539, I heard
him 56/79. May be good propagation… anyway, for small EH-Antenna
placed at 2- meters above the ground- it is very good. Then I
had QSOs with OK1HAJ, RV3QX, SP9FVO, YU5R, GM0IXO, ON3URT, OZ1HVL,
UA4SKW, SP4NDV, UT0EG, DR600UL, RA9FFF, UN1L, RA9JAT, RM9WK, ON3WP/qrp,
LA9SN, RD3BD, RV3SBS
So, I decided do not remove the EH- Antenna and tested
it in next days. For me it was interesting how the antenna would
be worked at show conditions.
