The Bullet-9B is a multi-core balun with a compact enclosure (looks like a bullet) enclosure that is lightweight and easy to transport for your fixed/portable ALE, T2FD or BBTD antenna systems. Also useful for rhombics and other wire antennas needing balanced 450 ohm output. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with side eye bolt output.Use a 500 ohm non-inductive termination resistor for the T2FD when using this balun.

This transformer requires a feed line choke to isolate the coax feed line from the antenna. A coax noise filter at the radio end of the coax is also recommended to reduce common mode noise current picked up by the coax braid.

Available in 500 watts and 1500 watt models



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.

Also make sure you connect a good RF ground to the transceiver ground post.

Note to Flex Radio users:  Use snap on ferrites for firewire cable, speaker cable and mic cable,  Ring ferrites for Antenna output and DC power.

For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.

 

If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
