Product Details
Brand: Palomar Engineers, Inc.
Country/Region of Manufacture: USA

Bullet End Fed Long Wire (EFLW) Antenna Wire Kit for end fed long wire antennas - choose 41, 71, 111, 155, 173, 203, 268 foot lengths complete with end insulator, #14 Insulated stranded copper wire and spade lugs and heat shrink for lugs for attachment to an optional Bullet 9:1 unun.


Insulators are a very stealthy, strong, pair of 2 PVC, 2 1/4" long. 1" wide. 1 1/8" hole separation wire antenna insulators and may be black, gray or white depending upon inventory

See related products for 9:1 transformers from 100 watts to 5KW, 9:1 toroid kits, and feed line chokes.

For a complete installation you will need 9:1 unun, wire kit, appropriate length of coax, and feed line choke (SOFLC is easiest to use and change position as you tune the antenna).

Bullet Antenna Length - feet (41, 71, 92, 111, 155, 173)
Corresponding Counterpoise length feet (16, 42, 90, 37, 95, 80) - place feed line choke on coax at this measured length from 9:1 unun

TECHNICAL NOTE: If you are building your own End fed Long Wire antenna, don't forget the end fed coax choke (or equivalent counterpoise) which is required to make the antenna operate correctly! End fed coax choke part numbers are SOFLC, EFFLC-240


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
