Bullet 50:100 (2:1) HF Balun, .1-61 MHz, 500 Watts PEP, Loop Antenna
New improved version now goes down to 100 KHz and up to 61 MHz < 1.5:1 SWR!
The Bullet-2B is a dual core current balun with a compact enclosure (looks like a bullet) enclosure that is lightweight and easy to transport for your portable loop antenna solution. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with side eye bolt output. Rated 500 Watts PEP Watts from .1-61 MHz.
This transformer requires a feed line choke to isolate the coax feed line from the antenna. A coax noise filter is also recommended.
Loop antennas are some of the best radiating and receiving antennas you can make. They can be in a triangle (called a delta loop), square or rectangle or even a circle. Horizontal loops can be fed anywhere that is convenient. Vertical delta loops(circumference length=1005/f(Mhz) are best fed 1/4 wavelength (length=246/f(Mhz)) from the top point down one side.
NOTE: due to the nature of antenna
systems and the modifications many users perform and the transmitter
power levels that may be applied higher then the specifications, the
antenna systems are NOT RETURNABLE unless they are unused, in the
original packing with the original invoice and a return request is made
withing 30 days of original purchase.
