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.
Generator RFI testimonial:
Bob Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and took out all the electrical noise. I may want some more toroids from you at some point for other interference problems I have here. Ken VE3KCY

Want to make up your own RFI kits for a particular operation? Here are links to some of typical RFI solutions used in portable operations:
If you use a computer for logging in your portable operations, RFI getting into computers will often lock up your computer and/or radio and a computer RFI suppression kits may be helpful
Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.
Portable Antenna Kits
If you need an effective portable antenna which folds up for transport yet is easy to deploy at your operating site, consider the BULLET series of end fed wire antennas.
