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


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.
