Attic Coaxial-Cable Trap Dipole for 10, 15, 20, 30, 40, and 80 Meters NU3E
Attic Coaxial-Cable Trap Dipole for 10, 15, 20, 30, 40, and 80 Meters NU3E.
A coaxial-cable trap dipole antenna installed in the attic provides a surprisingly effective solution to HF operation on the 10, 15, 20, 30, 40, and 80 meter amateur bands at a QTH with restrictive covenants that prohibit outside antennas.

Bent element yagi for attics
Bent element yagi for attics. This is a horzontally polarized three Element Yagi. The bent Elements cause very little performance lose.
When you consider it is only 8ft. 5" wide and 7ft. 6" long and still has 6.2dbi gain and 20db front to back ratio.
And when you off center feed it you get a perfect 50 ohm match to coaxial cables.The SWR is less than 2to1 for 600khz.
Not bad for a Antenna that the neighbors don't even know exist.
