Antenna for 50 and 70- MHz Band

By: Alex Karakaptan, es4uy, uy5on

The antenna was designed several years ago, when I got Estonian call sign ES4UY. With the call I able use 50 and 70- MHz bands from Estonia. Need to say that I was in a very rare square- K049CJ. So I need an antenna for those bands. Restricted place could not allow me to create something serious. So, wire in length in 3.75 meter was placed on to perimeter of my window then the wire was fixed at balcony. The wire was connected to the home brew ATU. Counterpoise in length 0.7- meter was connected to the ATU. Figure 1 shows the antenna on the window. Figure 2 shows design of the antenna. Figure 3 shows schematic of the ATU. Figure 4 shows design of the ATU.
