Bullet 50:600 (12:1) HF Balun, 1.8-61 MHz, 500/1500 Watts, T2FD, BBTD, ALEProduct DetailsMPN: Bullet-12BCountry/Region of Manufacture: USAType: NEWInput ohms/Output ohms: 50 in, 600 outFrequency Range < 2:1 SWR (MHz): 3-30PEP Power Rating (watts): 500Weight (pounds): 2Antenna Compatability: T2FD, BBTD, ALE, RhombicThe Bullet-12B-500 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 600 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.
NOTE: We rate our Bullet baluns (and ununs) VERY conservatively at 500/1500 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 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.
12:1 ununs show 9:1 unun picture but internal construction is set for 600 ohm output rather than 450 in 9:1
