The Bullet-16B 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 low power rhombics and other wire antennas needing balanced 800 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.
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 watt and 1500 watt models
Tech Note: If you are building a T2FD/BBTD antenna and you need a matching resistor, use either the TR-800-600 or TR-1000-600. If you are making the 130 foot folded dipole version and you need wire, the DWK-160 will work nicely. To minimize feedline radiation use a choke at the antenna feed point with the Bullet-16B-500EB or use the hybrid 16:1 balun with built-in 1:1 choke, Part# BULLET-16-1-500EB. See related products for these items.
NOTE: We rate our Bullet baluns (and ununs) conservatively at 500 watts PEP with a 50% duty cycle (FT-8 or CW)). 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 75 watts continuous or 150 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.
50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
