New improved version now goes down to 500 KHz (25 dB common mode AM Broadcast band suppression) and up to 61 MHz < 2:1 SWR. Choose Balun only or add optional dipole wire kit (wire, Insulators, Spade lugs for attachment to balun - assembly required). Center insulator and Balun in one case - 1/4" stainless hardware and 5000 real watts rated!

The SBullet-1B-5000EB is a multi-core current balun with built in feed line choke offering up to 60 dB (on 40 meters) of common mode current rejection (plenty for most applications) to keep RFI off the coax outer braid during transmit operations. The SBullet-1B-5000EB is housed in a waterproof PVC enclosure that is lightweight yet robust in features and makes a great high power antenna feed solution for dipoles and other balanced antennas. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with dual side eye bolt output and wire strain relief. Rated 5000 Watts PEP Watts from .1-61 MHz. SBullet-1B-5000EB weight is 2 pounds.

This balun/feedline choke keeps TRANSMIT RFI off the coax outer braid while transmitting. If your station suffers from common mode RFI noise on RECEIVE, then use one of our Common Mode Coax Noise Filters (such as the CMNF-5000) that suppresses common mode noise on RECEIVE operations.

Make a FAN DIPOLE using optional dipole kits (e.g. 80/40 would use extra 40 meter dipole if you chose the 80 meter dipole lit for this listing).

NOTE: We rate our Bullet baluns (and ununs) VERY conservatively at 5000 watts PEP with a 50% duty cycle. Some manufacturers selling low cost baluns may use a 5% duty cycle for their PEP rating to make it appear you get a higher rated balun for a lower price, but you may in fact be getting be getting less. Their 1500 watts PEP really means 750 watts continuous or 1500 watts at a 50% duty cycle compared to our 250 watts at 50% duty cycle. Our baluns typically cover a larger frequency range under 2:1 SWR which make your transceiver happy and probably will last longer with less electrical stress.

Remember we over engineer our products, to out perform our competition - just compare the weight of our baluns to theirs and you will know we put much more into our products so you don't have to worry about failure at a critical moment.

Often it is difficult to slip beads on a cable because of a plug or connector. Split beads solve this problem. They come in two halves that fit over the cable. A plastic snap cover holds the two halves together and holds the assembly on the cable.

For RFI use, mix 31 is effective from 1-300 Mhz, mix 43 works from 20-250 Mhz, Mix 61 is for 200-2000 Mhz, and mix 77 favors .1-20 MHz. These frequencies are those of the interfering signal to be eliminated, not the operating frequencies of the equipment to be protected.

Not sure of what sizes you need or solving a RFI problem with devices using multiple size cables? Try the Ferrite Snap On Combo Pack which has sizes from 1/4″ to 3/4″ with either Mix 31 (1-300 MHz) or Mix 61 (200-2000 MHz) or Mix 75 (150 KHz – 10 MHz).

Application Notes

Application Note for using these Snap On split beads: How Many Chokes do I need?

You can very effectively increase the choking impedance of smaller cable by using a large hole ferrite bead and wrapping the cable through several times. For particularly difficult common mode current/RFI problems you may need a choking impedance as high as 5-10K ohms. Using multiple beads and multiple turns through each bead will give higher impedances up to a point. At higher frequencies, when the number of turns approaches an electrical wavelength, the choke becomes resonant due to stray capacitance and the inductance of the cable and limits the high end impedance values to less than the above table points.

Some example of ways to wrap cable are shown below.

These snap-on chokes are useful for reducing RFI in public address system amplifiers, speaker wires, mic cables, mixer panels, coax cable, telephone wires, computer sound card speakers, dsl/cable connections, remote control heads for ham transceivers (Especially FT-100, FT900, IC-706, IC-7000), AC power cables, DC power cables, home theater cables, video cables, HI Fi cables, guitar amps, linear amp cables, etc.

They are also helpful in suppressing common mode noise/RFI in radio and TV receivers, audio and RF amplifiers. They can also help suppress noise generated by treadmills, exercise equipment, fish tank heaters, oil heater pumps, fluorescent lights, motors, cable modems, DSL modems, computers, and many other electrical devices. Common mode current reduction in computer cables often helps speed up computers.
