The Bullet-4-1-500EB (500 watts PEP) or the SBULLET-4-1-1500EB (1500 watts PEP) are both multi-core, 4:1 (50 ohm to 200 ohm) balun plus a 1:1 feed line choke in a single compact (looks like a bullet) enclosure that is lightweight and easy to transport for your fixed/portable.Common Mode Rejection Ratio (CMRR) up to -30 dB for internal feed line chokes.

Very useful for multi-band Off Center Fed, folded dipole and multi-band loop antenna systems. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 UHF coax connector and output with side eye bolt output.

Dimension of 1500 watt model is 8.5 inches tall, 6.5 inches wide tip to tip on the eyebolts.

Shipping weights are 2 pounds for 500 watt version and 3 pounds for 1500 watt version.



Remember we over engineer our products, to out perform our competition - just compare the weight and frequency range 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.


These RFI kits are specifically selected to cure most household computer device RFI problems. It contains ferrite toroids for AC or DC power supply protection and Snap On ferrite spli beads selected to eliminate RFI from 1 to 1000 Mhz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
