    Before I set up a 260 foot long wire across my back yard, would there be any advantage to using my MaCo 103C and a rotor for Short Wave reception?



    I would like the fact that I could turn to tune in a stronger signal reception.
    Would this work better than a long line?

    I guess I could do both an then compare, but there must be a good reason most people don't use their beams for shortwave reception..

    No advantage at all.
    Which part of SW you listen the most?

    The M-103 will only be directional near it's design frequency. It will work quite well for frequencies above 25 MHz but with the sunspot cycle where it is you won't be hearing much. Below about 25 MHz both directionality and performance will fall off sharply. There is a reason antennas are a certain size as related to the frequency they are designed for. Go with the long wire and make it as long and as high as you can. You can't go wrong with that. Back in the 80's I was into SWL quite heavily and had a Wilson Shooting Star dual polarity beam. It could not hold a candle to my 600 foot wire antenna on the lower bands or even my dipole which had 66 foot long legs for a total length of 132 feet.

    Best to either run a long wire or get a discone antenna. Those work best for SW listening. Just my experience.

    A discone is for VHF and UHF unless you want one about 40 feet high and 40 feet in diameter. :D

    Long-wire it is: Multi Strand, 10 gauge with insulation, 260 feet long at 8 feet above the ground.

    Hooked up to a Hallicrafters S-108..

    Unless you wwnt to do some AM broadcast DX'ing or listen to longwave try half that length as a start. Little is to be gained for general listening by going to great lengths. I had great reception with a 75 foot antenna at one time. The only reason I eventually went with a 600 foot antenna was my interest in European AM stations and worldwide longwave stations. That and the fact it worked REAL good into Japan on 20m.I could hear an ant fart in Nagasaki :)
