4:1 Baluns/Ununs

NEW PRODUCT ALERT

BULLET™ END FED ANTENNAS - 80-6 Meter - 100/500/1500 Watts

SHORTER, SAFER, MORE BANDS THAN EFHW

Bullet end fed antennas are shorter than conventional dipoles, yet deliver superior performance on many bands using the radiating coax as part of the antenna. They come in a variety of power levels, and work great for portable or permanent installations. Thousands in use world-wide! Selected models available at Ham Radio Outlet and all available on company website where full details on these antennas and many accessories are shown.

4:1 impedance transformers (Baluns and Unun configurations) are available in kit form or assembled form in a weatherproof  Current Unun and Balun Enclosure which we call CUBE Baluns™ and CUBE Ununs™. All 4:1 impedance transformers use ferrite cores and the kit forms can be configured as a balun with balanced output of 200 ohms or as ununs with one side grounded.

4:1 baluns are designed for 50 ohm unbalanced (coax) input to 200 ohm output (either balanced or with one side grounded).

4:1 Baluns are useful between balanced lines for center fed Zepps, Off-center fed (OCF) dipoles with coax, G5RV antennas, full wave loops, NVIS dipoles that are close to ground and have impedance levels near 200 ohms or high impedance feeds for log periodic beams.

4:1 ununs are useful between coax and vertical antennas, monopole verticals or long wires with load impedances near 200 ohms.
