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.
Home Theater/Audiophile RFI Kit
The Home Theater RFI Kits are specifically designed to cure most home theater systems triggered by Radio Frequency Interference problems from AM, FM, CB and Ham radio stations. The kits contain ferrite toroids (“Ring” shaped) for the AC power cord protection and “Snap on” ferrite beads for HDMI, audio, video and speaker cables. The ferrites are selected to eliminate RFI from 1 to 1000 MHz. The ferrites are easy to install, don’t require modification of the protected equipment and work in almost all cases to suppress annoying interference issues.
