Fan Dipole for 80/40 Meters - 500/1500/5000 OptionsProduct DetailsPalomar Engineers Fan Dipole kit for 80 and 40 meters. Choose 500, 1500 or 5000 watts PEP option. 135 feet wide for 80 meters and 66 feet wide for 40 meters. For best results install so end are 5 feet apart and as high as possible.
Dipole wire kits come assembled to selected balun - just add coax and raise with paracord and use our pulleys for ease of installation. Keep each dipole end approximately 36 inches minimum apart if possible. Adjust 80 meter length first and then 40 meter length as there will be some interaction with each other.
You can also add additional option dipole kits. Just add to cart in addition to this antenna. Be sure to space ends 3-5 feet away from the other dipoles. Tune the lowest frequency first, then next highest, etc.
If you want different band combinations, choose the dipole wire kits needed and then select the Bullet-1B-500, CB-1-150EB or CB-1-5000EB for 500/1500/5000 watts rating.
You can have more than 2 bands on a fan dipole, just select an additional band using our convenient Dipole Wire Kits!

1:1 feed line Chokes (also known as feed line current chokes, common mode chokes, line isolators, current mode chokes, and 1:1 baluns/ununs) are available in kit form or assembled form in a weatherproof Current Unun and Balun Enclosure which we call a CUBE™. All 1:1 chokes are ferrite based and are designed for 50 ohm coaxial cable input and 50 ohm output. 1:1 Ferrite toroidal or bead chokes have a higher choking impedance than our popular Sleeve Chokes and various models are available for specific frequency ranges and power levels.
1:1 Chokes are useful for choking common mode currents that may flow on the exterior of the coax cable shield while allowing the signals on the interior of the shield and the center conductor to flow unaffected and keeping the common mode current on the antenna. They isolate the coax shield and prevent it from becoming part of the antenna system.
1:1 Chokes are useful between balanced lines for center fed dipoles at their fundamental frequency (468/f (MHz), beam antennas with a 50 ohm balanced driven element, G5RV, loops, yagis, NVIS antennas, mobile installations, portable antennas and anywhere common mode current (or RFI) is a problem. They are also helpful between transmitter and linear amplifier or between linear amp and antenna tuner or as isolation chokes where higher choking impedance is needed (in the range of 2K-7K ohms).
1:1 Chokes are also very useful as feed line current chokes at the “radio end” of the antenna (we call them coax noise filters) where they choke/filter common mode current induced onto the coax shield from radiated waves (from your antenna, and other sources such as DSL routers, computer devices, plasma TVs, etc. originating in your house or your neighbor’s house). For RFI issues see RFI/EMI Solutions for general use or for specific radios and devices.
For best results we recommend a 1:1 choke at the “antenna end” of the coax and a coax noise filter at the “radio end” of the coax. (A side benefit is a reduction in noise level caused by common mode currents). 1:1 chokes are also available as Sleeve Chokes (Slip on or Snap on) for ease of installation and light weight on the antenna.
