    I'm discovering this video a bit late, and I find it even more instructive and entertaining as usual. Going all over to Italy with 100 mW is quite something, I must say. I didn't expect this.
    Thanks once more to you Walt for my favourite UA-cam channel. You're such an inspiration.

    Walt, another awesome video. One gizmo you might want to look at is the MFJ 16010 random wire tuner. I have one and it will match practically anything. I suggest it because it's tiny and inexpensive. Great size for travelling. It is a manual tuner, but takes very little time to find a match. I can run my IC-7000 with a 15' piece of wire, hung inside my basement, and still make contacts. Putting a random wire outside is awesome with that little tuner. Keep doing your super videos! I absolutely love them.

    I was trying to figure out which way each antenna was running looking at your map. Do the lines represent the axis of the antenna. I am thinking they do. Not sure which one is the halfwave on 20.
    Baring some coupling to other antennas or structure, the halfwave one on 20 should be directive broadside while the other one has a null broadside on 20. On 40 I would expect the longer one to always be better signal strength wise regardless of the direction except since the 40 meter halfwave has a null off the ends, the other antenna might equal or beat it there depending on height above ground.

    • @COASTALWAVESWIRES
      @COASTALWAVESWIRES  Рік тому

      Yes, the lines represent the same orientation of the wire. As this was a rough experiment I'm sure there was some small coupling or reactance from surrounding structure etc. Like I said in the video the random was slightly longer than a half wave for 20 and was absolutely directive broadside as I showed in my discussion at the end of the video.

      Hi Jeff...This is MJ, WO9B from Spark Plug. Really cool review. Let me correct a couple of items from your video. The impedance transformer is actually 64:1. I say that with just a bit of tongue in cheek as it is actually just a bit short of that. When I do my testing on each unit, I use 3200 ohms as my base, which of course is the 50 ohm transformation for a 64:1.

    Hello,
    Maybe I speak in Russisn about of Antennas? Because I do not speak in English.
    Любая почва имеет разный состав:
    Одна земля очень плодородная,поэтому очень сильно поглощает в себя любые радиоволны.
    Например,другая земля состоит из глины,а глина больше всего отталкивает от себя радиоволны.
    Если почва мокрая,то земля будет очень сильно поглощать радиоволны.Но,если почва сухая,то она меньше будет поглощать радиоволны.
    Также существуют препятствия для радиоволн в виде высокоэтажных зданий и высоких гор.
    Поэтому,прежде,чем выбирать антенну для приёма или радиосвязи,нужно учитывать состав почвы,её сухость или влажность и естественные препятствия для радиоволн.
    Например,на вашем участке глинистая почва,но она мокрая,тогда в этом случае будет почти одинаково,если вы используете вертикальную антенну или горизонтальную антенну,подвешенную очень высоко.Если же глинистая почва сухая,то горизонтальную антенну можно опустить ниже к земле.
    Например,на вашем участке плодородная чернозёмная земля и прошёл дождь,тогда в этом случае самой эффективной антенной будет вертикальный штырь,при условии,что отсутствуют естественные препятствия для радиоволн.Если же чернозёмная земля сухая,то можно использовать горизонтальную антенну,подвешенную высоко от земли.
    ВСЕГДА НАДО ПОМНИТЬ, ЧТО ВСЁ ВСЕГДА ОТНОСИТЕЛЬНО, ПОТОМУ ЧТО ОЧЕНЬ СИЛЬНО ЗАВИСИТ ОТ СОСТАВА ЗЕМЛИ, ЕЁ ВЛАЖНОСТИ И ЕСТЕСТВЕННЫХ ПРЕПЯТСТВИЙ.
    УЧИТЫВАЯ ВСЁ ЭТО, МОЖНО В ТЕЧЕНИИ ОДНОГО ДНЯ МЕНЯТЬ АНТЕННЫ С ВЕРТИКАЛЬНО ШТЫРЯ НА ГОРИЗОНТАЛЬНЫЕ ДИПОЛИ ИЛИ ВООБЩЕ НИКОГДА НЕ МЕНЯТЬ ИХ.
