Impedance Transformers (<1:1, >1:1)

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.

Palomar Engineers offers a variety of impedance transformers configured as Baluns (balanced coax to unbalanced load) or Ununs (unbalanced coax to unbalanced load) for  matching typical 50 ohm feed line impedances to antenna or other load impedances.

We specify impedance ratios as an output to input ratio where the output (or load) is given first and the input is given second (e.g. 100:50 (2:1) would mean a 100 ohm output and a 50 ohm input; a 25:50 (1:2) would mean a 25 ohm load and a 50 ohm input).  Most all products use a 50 ohm input unless otherwise specified.

We have products that are available as kits for the do-it-yourself (DIY) person or fully assembled and tested units for the “Plug & Play” crowd.

Our impedance transformers are available using two different topologies: Binocular cores or  toroid cores with multiple turns for increased effectiveness and wide band frequency transformations.  We utilize single and multiple core transformers using high order windings when needed to extend product performance.

We rate the power ratings as watts PEP (Peak Envelop Power) with standard duty cycles for various modes. To determine the PEP rating required for your needs, see: Choke & Transformer Power Ratings
