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


These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
