Broad Band Terminated Dipoles (BBTD), Tilted Terminated Fold Dipoles (T2FD) and Balanced Termination Folded Dipole BTFD) antennas can be designed to cover a large range of frequencies between 1.8 30 MHz. Longer length antennas generally provide better low frequency efficiency but take up a larger footprint of land. One BBTD that has worked well at the AK6R antenna farm is shown below. Many other designs are available and can be found at www.HFLINK.COM as well as other internet sites. Your mileage may vary using this antenna, but as a general coverage antenna for ham and shortwave broadcast, the simplicity can’t be beat even though an individual dipole on a specific band may out perform this broad band dipole. Palomar Engineers has all the parts you need to build this antenna, so why not give it a try?
Depending on the source of the antenna design, different value baluns are specified. Our Bullet(TM) baluns in ratios of 9:1, 12:1 and 16:1 are excellent for this type of antenna as they are broadband from 1.8-61 MHz and will take up to 500 watts PEP.
Palomar Engineers Fan Dipole kit for 80 and 40 meters. Choose 500, 1500 or 5000 watts PEP option. 135 feet wide for 80 meters and 66 feet wide for 40 meters. For best results install so end are 5 feet apart and as high as possible.
Dipole wire kits come assembled.
You can also add additional option dipole kits. Just add to cart in addition to this antenna. Be sure to space 3-5 feet away from the other dipoles. Tune the lowest frequency first, then next highest, etc.
If you want different band combinations, choose the dipole wire kits needed and then select the Bullet-1B-500, CB-1-150EB or CB-1-5000EB for 500/1500/5000 watts rating.
Likewise Termination Resistor values vary from 500-1250 ohms and we have a good selection shown HERE:
