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.

BUY THIS KIT NOW TO SOLVE YOUR RFI ISSUES AND REDUCE COMMON MODE RECEIVER NOISE LEVELS FOR YOUR ICOM 9700 VHF/UHF RADIO. ALSO WORKS WITH MANY BRANDS OF HAM/COMMERCIAL HF RADIOS WITH SIMILAR FREQUENCY RANGES.

This kit will help reduce or eliminate:

1. Radio Frequency Interference (RFI) to electronic devices including audio/video systems, computers, telephones, garage door openers, alarm systems, and home appliances, in your house or your neighbor’s house.

2. RFI from other electronic devices such as switching power supplies, LED and fluorescent lights, battery chargers, Ethernet cables, solar systems, kitchen appliances, and cable/satellite TV systems which generate common mode currents on your radio cables.

3. These filters help cure SWR problems between transceiver and a linear amp and between transceiver and antenna tuner or direct to antenna. The DC power line filter helps keep common mode current out of the power line which could cause interference to other devices connected to the same power source.

These chokes use a ferrite core material that is effective in suppressing RFI from transmitters and receivers experiencing a high noise floor in the .15-2000 MHz range. DC filter effective from .15-10 MHz, Snap On filters effective from 1-500 MHz and 200-2000 MHz identified for easy installation on selected antenna and I/O cables.

The ferrite split beads and ring filters are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.

Kit Includes 1 AC/DC noise reduction ring filter and 11 snap on filters for coax and I/O cables. Quick installation - immediate RFI/noise reduction. No radio mods required.

If you use a linear amplifier use a Palomar Engineers amplifier RFI kit for additional RFI interference suppression.
