EH- Antenna for the 160- meter Band

 

Parameters of the antenna are really good. At the frequency 1.85- MHz it is Pass Band more the 100- kHz at SWR 1.0: 1.02. The antenna has big sizes so tune the antenna at its working position. Remember, that all objects near the antenna could influence to the parameters of the antenna. Try to keep space near the antenna at radius 2- 3 length of the antenna free from anything.

 

However, above stated is not about me. I have no free place for the EH- Antenna. The antenna was installed at my workplace at the ground floor. Near the antenna there are lots objects that hindered the antenna operation. At the background it is showed a EH- Antenna for the 40-meter (25- cm in length). Figure 5 shows the installation. Do not repeat my installation of the EH-antenna because it is dangerous for life!

 

I turn on the EH- Antenna to my transceiver through a 1.5- meter coaxial cable. Near the antenna an RF- Choke is installed. It is six coils coiled by the coaxial cable around a ferrite ring. I turn on my transceiver and take my straight key. Time is near 13.00- GMT, not good time for QSO on the 160- meter. However, I hear several stations and first QSO with RK3PA is done!

 

Next week (I have no lots time to work in the Air) I made QSO with UR4LPQ, LA6YEA, RU4SU, OZ1LXJ All QSOs were made at EH- Antenna in 2- meter height and 10- 15 Watts going into the antenna!

 

Final test the EH- Antenna was made when I installed the antenna at 1.5- meter above the roof of my house, that is near 8- meter above the ground. Figure 6 shows the antenna on the roof.
