Super Bullet Features:

  • Uses proprietary broadband impedance transformer design for maximum bandwidth with SWR < 2 from 1.8-61 MHz for 1500 Watt model and 1.8-30 MHz for 3000 watt model
  • 1.5 KW PEP/FT8 rated with over 1 pound of ferrite for maximum duty cycle modes
  • 50 ohm SO-239 input connector, combo halyard hoist/wing nut tightened output eye bolt
  • Has coax shield/ground stud for extra counterpoise for solving tough matching issues
  • DC grounded impedance transformer to bleed off static electricity and protect sensitive receivers
  • All stainless steel connectors for long life and weather resistance
  • Easy to use, works in all climates, water resistant, conservatively rated for long life and high duty cycle transmission modes
  • Beats all the competitors: Best built, best bandwidth, best power rating - buy the best, forget the rest!

We sell the Bullet and Super Bullet matching units separately so you can add you own wire type and length (see table of suggested lengths below) or you can purchase a complete antenna system including wire and end insulator.

For best results we recommend that the coax feed line be at least 1/4 wavelength on the lowest operating frequency since the coax braid is used as a counterpoise if you don’t use the external counterpoise terminal on the matching unit. We also recommend a feed line choke at the end of the coax feed line near the radio to prevent RFI common mode current from interfering with the radio.

Suggested wire lengths for 1-61 MHz operation (measured from Bullet wire point):

Bands Covered (meters)

Wire Length (feet)

Minimum Coax Length (feet)


35-43, 49-63, 70-85



35-45, 54-64, 67-77



38-44, 55, 60, 68-73



68-73, 85, 92, 102, 120-125



135, 141, 173, 203



For best results raise the Bullet matching unit as high as possible (use a tree or vertical support) and then extend the antenna wire horizontally or as an “L” (horizontal with vertical end drop). The antenna may also be deployed as a sloper with the Bullet matching unit at the top (best) with the wire sloping toward the ground (with the end high enough to avoid contact by humans or animals), or at the bottom of the sloper with the antenna wire rising to a higher point (see typical configurations below).

Additional Typical Antenna Configurations:

Antenna Length Modifications: For best results, chose a length from the table above as these lengths will form a non-resonant antenna for the amateur bands indicated.The antenna length should NOT be ¼, ½ wavelength on any frequency that you transmit as the impedance will be very high (or low) and will not transfer through the matching unit at a favorable impedance to your antenna tuner.The theory of the antenna length is to make the antenna non-resonant on any amateur band so that the impedance at the antenna side of the matching unit is in the range of 200-600 ohms and when divided by 9 will be in the range of your transceiver antenna tuner.

Any length of 50/75 ohm feed line ok (over 35 feet minimum) but longer feed lines over 50 feet may show reduced SWR on some bands due to soil conductivity, nearby objects, etc. Due to local ground conditions, antenna height and feed line length, SWR may vary and an antenna tuner may be required or some bands to bring SWR at end of feed line to acceptable levels.Use of one or more ¼ wavelength counterpoise(s) connected to the ground post of the matching unit may also improve antenna efficiency and reduce SWR on certain bands.The first counterpoise should be installed under the horizontal portion of the antenna for best results.
