number. I believe the two 40m elements are quite similar to an EF-240S. It sits about 6 feet under a 315-310. It works OK on 40 but bandwidth is limited. It requires a tuner on SSB. Since I dont have one there, I stay off 40 SSB. Although the wire linear loading system looks spindly, it has not failed in about 8 years. I have a Mag-240N in Truckee. It sits about 6 feet above a Sigma 180 rotary dipole and about 12 feet above a 3el SteppIR. The two beams are aligned and the dipole is turned 90 degrees. Interaction does not seem to be much of a problem. At first, in a different stacking order (Top-Bot = 40-SteppIR-80) and without the 90 degree shift, interaction was bad between the two beams. Bandwidth on the 240N is excellent at the factory recommended settings, almost enough for the entire band. In the bottom 20 kHz or so I usually switch in a tuner to keep the Alpha happier, but I can survive without it. At the next maintenance opportunity I intend to lengthen the elements a bit to eliminate even that. It feels significantly louder than the shorty, but it is higher and on a ridge, so this is an apples and oranges comparison. I love all these antennas. I envy N6NZ who has a 340N! I am certain you will appreciate the advantage of the 240N over the 240S. 73, /Rick N6XI Pete Smith wrote: > Has anyone had enough experience with one of these to compare it to an > EF-240S or other short yagi (like the Cushcraft or Mosley antennas? > I'm thinking about replacing my EF-240S, which sits 6 feet above a > C-3E.
