Broad Band Terminated Dipoles (BBTD, T2FD)

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?

BBTD at AK6R 1024x726 - Broad Band Terminated Dipoles (BBTD, T2FD)

 

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.

The Ferrite Snap On, Ring and slip on sampler Pack is a convenient solution for troubleshooting RFI/EMI in the 200-2000 MHz region with various diameter cables ranging from 1/4″ to to 1,4″ for use as either single turn or multiple turn ferrite chokes using ferrite rings, slip on beads and snap on beads.

The filters are useful for RF coax, AC/DC power cables, and device interconnection cables.

Always use a snap on or ring with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turn). Included in these combo packs are our most popular snap on sizes as follows:

Combo Pack includes the following:

F240-61 ring – 1.4 inch ID – 2 pieces

FSB61-1/4 – 1/4 inch ID – 2 pieces

FSB61-1/2 – ½ inch ID – 2 pieces

FSB61-3/4 – 3/4 inch ID – 2 pieces

FB102-61 - 1/2 inch ID slip on bead - 2 pieces
