The solution is quiet obvious: With an end-fed wire antenna from a kite up in the sky led down to the radio on the ground. They ‘see’ 80M band antenna as a very large resistance because of large inductances of helix coil so the influence of one antenna on the other is insignificant. Many hams don’t have room to install one. There is an extra benefit of a ground connection for an earth rod if required. This step also applies if you 39 re using an externally mounted antenna e. 52 - Center Fed-Zepp Antenna for 80m - 40m. DIPOLE IMPEDANCES.

The Par Electronics EF-SWL is an end-fed short wave antenna optimally designed for 1-30 MHz reception. Years ago the end fed antenna was the most popular HF antenna type used by radio amateurs. The attic antennas can handle the other bands. Due to 40m being an end fed 1/2 wave vertical dipole on this system, there is the potential for having RF on the shield of the coaxial feedline and radiating as part of the antenna. Home / HF Base / 6-80 meter J-Pole Jr 34 foot end fed HF antenna. End Fed Half Wave antennas have only one long side wire so the antenna feed point can be closest to the location of the shortwave radio, unlike the dipole antenna that is twice as long and must be fed at the center of the antenna. 5MHz) and 40m (7MHz) but are a bit concerned about how much space you will need for an antenna.
