The simple balcony
vertical HF antenna made with plastic fishing pole. Just along
the pole I install copper wire in 7 meter length. Then was installed
ATU. It was used home brew tuner. For each band was used one counterpoise
in length 0.8 x lambda/4. The length is used because the counterpoises
placed on the floor or on the ground. The antenna was used by
me in the field and at my vacation in hotel. Figure 1 shows design of the antenna.
At first I install
the antenna on the ground and with help commercial antenna tuner
LDG Z-100 match the antenna on the HF bands. After antenna was
matched, I take data for Land C from the tuner.
shows the data for all bands (above the 80- meter, I just lost
the data by accident). Base on the data I made ATU. The unit was
made in plastic box, I used low power parts because I plan work
QRP with the antenna. Antenna was tested in the field and in the
hotel and provided good result.
