Modified DL1BA Dipole Antenna for 40-, 20-, 15-, and 10- meter Bands

By: Igor Vakhreev, RW4HFN

DL1BA Antenna (Antentop 01- 2015, pp: 53-55, Dipole Antenna for 40- and 20- meter Bands) may be modified for working at additional 10- and 15-meter Bands. Figure 1 shows design of the antenna.

As you can see from the Figure 1 parts for additional bands are added into the antenna design.

The MMANA file of the Modified DL1BA Dipole Antenna for 40-, 20-, 15-, and 10- meter Bands may be loaded: http: // www.antentop.org/019/rw4hfn_modified_dl1ba_019.htm

Simulation of the antenna in MMANA showed that the antenna may be tuned at resonance at all of the four Bands.
