    By far the best info on antennas I have ever seen! Saved this one. Superb easy to understand reference material for a new ham. Great Job!!!

    I am nearly 70 years old. I got my General class when I was about 16. I have been inactive for 45 years but have kept my license up. When I was a boy, my dad helped me erect a beam antenna. It only cost a few hundred dollars back then! Now that I am wanting to get back into the hobby, I don't have the room for this nice beam but do have a small yard and home to play with. The antenna is the driving force that is preventing me from getting back into this. Thanks for the video.

    Good video.

    • @davecasler
      @davecasler  3 ปีที่แล้ว

      Yes, take a look at the ARRL book called "Small Antennas for Small Spaces." Attic antennas do work. Or look at a hamstick for your favorite band, or try a mag loop.

    Hi Dave. My name is Arthur. KD2pxe. I currently am new to ham radio I have a technician license. I'm living in a top floor 3rd FL apartment and using a homebrew J pole on 2 meters. It hangs from a hook in the ceiling. I would like upgrade to HF but cannot put up an outdoor antenna and have no access to the attic. I was thinking of putting a wire around the perameter of the ceiling. I was thinking of an acordian style folded wire for 20 meters. Do you have any thoughts that could help with this.

  • @bilboXbartok
    @bilboXbartok 6 ปีที่แล้ว

    Thanks for the video! I was a ham for some time, going up to Advanced class... then, due to various reasons Iwas unlicensed for about 10 years... then last june, after studying for several months, I took both the Tech test, and the Extra test! 85 questions in one test setting! I made it out alive, and with a Extra class ticket! :) So much for the background... Most of this material i know pretty well, but appreciate seeing it all from a different viewpoint... I would have like more info about Hex Beams... but with the time alloted, this is probably all you had time for that kind of antenna! - AI6XK

    • @davecasler
      @davecasler  6 ปีที่แล้ว

      I haven't really done any videos on gain antennas because most new hams don't have access to them. Welcome back to ham radio! See you on the air.

  • @ForensicPI
    @ForensicPI 6 ปีที่แล้ว

    David I really appreciate your videos. I’m new on HF, and am using an Icom 7300, but with only a beginner’s basic vertical, and it’s not far reaching. Now that your video is two years old, I have the following questions. I am considering either the Cushcraft R-9, or High Gain 860. The reviews on the Cushcraft R9 seem better. Is there a better vertical than these two, that I’m not yet aware of. I have a roof eve mount ready for them. Bill Rhetts - KM6ESG

    • @davecasler
      @davecasler  6 ปีที่แล้ว

      I think you must mean the AV-680. The thing to note is that it covers only a tiny portion of the 80 meter band--you choose which portion. You might look at the less-expensive R8 and AV-640.

  • @TEN-TIMES-HARDER
    @TEN-TIMES-HARDER ปีที่แล้ว

    So if a dipole be it horizontal or vertical, bent, or even a 1/4 wave vert is half a dipole and uses the outer shield of coax as the other 1/4 wave if it don't have counterpoise radials.... is how its taught....
    So it gets confusing where we run a 1/2 0r 5/8 wave vertical. the coil at the feed point matches the impedance and forces the 1/2 wave antenna to have 50 ohm in the center of antenna not at feed point causing it to radiate feed point to tip, like a center fed dipole. "They" antennas are best with the feed point half wave or a full wave off ground.
    So does this mean that I want the center of my 1/2 wave vertical a full wave off the ground or still the feed point should be 1/2 0r full???

    Hi Dave,
    Great video. Very informative for anyone starting out in the hobby. I've been around for awhile and have the classic trapped tri-band beam. It's 35+ years old and just brought it down for some much needed maintenance. It was on a Wilson TT-45 tubular crank-up that is also undergoing some repairs to make it last another 35 years. :-)
    Keep these videos coming.

    I use a 3 band fan dipole in an inverted V configuration. All three bands are 2 to 1 for the frequentcies they are cut for. Can I use this self determination concept when attaching to the coil of the AV18VS or similar vertical? Thanks

    @NullaNulla 8 ปีที่แล้ว

    Nice video though I'd have made note that trapped verticals (the Cushcraft etc) are usually RATHER pricey :(. Each time I look they seem to sit around $1k AUD which I just cannot justify as much as I'd love one. If anything I need a good wind down/fall over tower of at least 40-60ft first (I know someone locally with 80ft but the mob that has it won't part with it until it falls down).

  • @ahmetozdemir7173
    @ahmetozdemir7173 3 ปีที่แล้ว

    Hello, thanks for video.
    can I ask something about antennas? Can a rod or telescopic antenna made of aluminum be used for electrical, magnetic and electromagnetic sensing? Why?

    • @davecasler
      @davecasler  3 ปีที่แล้ว +1

      Yes. There are signal strength sensors out there, but a lab grade signal strength meter would be very expensive. I've never seen one in ham use.

    @jrlepage 4 ปีที่แล้ว

    When viewed from above, do the two legs of the dipole have to form a straight line? If not, how acute can the angle be? In other words, can you do an inverted V configuration when viewed from the side that appears like an L (or even a V) when viewed from directly above?

    • @davecasler
      @davecasler  4 ปีที่แล้ว +1

      No, but keep at least the center part kind of straight.

    Thank you Dave, the information contained in your video was quite healthful. I’m relatively new to amateur radio and had been struggling with the different components of which the intent is just one, so many choices. After researching I believe the Cushcraft R9 is my choice. 73 W1LRZ

    Yaggi 4 element beam 27mhz can this antenna be used on other frequency with a atu. Great channel thanks.

    • @davecasler
      @davecasler  7 ปีที่แล้ว

      Not so much. The Yagi itself is a resonant antenna, and off-resonant frequencies will be attenuated. One thing you can do as a ham is to shorten the elements to create a ten meter antenna.

    Is picking up a lot of ground noise good or bad. yes I have fiberglass screening. Always seem to hear up the eastern states but just can't get anyone to hear me. And finally is aluminum framework for the screen impeding and grounded? And does adding additional ground radials help?km4ypd. George

    • @davecasler
      @davecasler  7 ปีที่แล้ว +1

      In theory adding a linear will help you get out better. But be sure to check the RF safety guidelines to be sure that you and others aren't receiving too much RF. My antenna is about a hundred feet from my station, so even at higher power, I'm well in the safety zone. 73

    Is window line the same as what we used to call ladder line?

    • @davecasler
      @davecasler  6 ปีที่แล้ว

      Close, but not exactly. True "ladder line" has spacers every so often to keep the wires apart. Window line is just oversize twin lead, 450 ohms rather than the usual twin lead 300 ohms. To save on plastic, manufacturers cut lots of holes in the plastic, giving the appearance of cutting "windows" into the line. Very often window line is erroneously referred to as ladder line, so often the term has stuck.

      No. The radials are not counterpoises. They actually form part of the antenna.

      occasionally, as a new Ham, I get the "vibe" from some that because I passed the test I am expected to just know some things. To a certain extent I guess that is true, but in college I didn't learn to be a social worker by passing required tests. I appreciate your TH-cam channel and especially your openness to share the hobby....that is quickly becoming a lifestyle...lol
