Palomar 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!
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.
