Included are the following chokes and installation guidelines:

RF Input: F240 toroid – 5-9 turns of RG-58 size coax through center

RF Output: FSB-1 (Big Clamp on) – 3 turns of RG-8 size cable

Relay Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole

AC Power Line: FSB-1 (Big Clamp on) – 3 turns through center

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
