    I've fooled with verticals for decades... the most effective one was my "Chicken Coop Vertical." It was simply a trap vertical in the backyard, but the counterpoise took me three full days of work to construct. I literally carpeted the backyard with chicken coop wire. While it was on the ground I took a propane torch and soldered every twist together to prevent oxidation. Then I used chopped up metal coathangers to tack down all the chicken wire (no digging). For a good while I mowed the grass high so as not to hit the wire... the weight of the mowed grass eventually buried the wire and it was never seen again and struck during regular height mowing. I was a great antenna for 20-years until I retired and moved away. Unless he wants to dig holes in the backyard, the new owner will never know it's there.

    This video is great. What you said at about 15:08 is exactly what I tell all the new hams that are worried about antennas. I tell them that the best part of antennas is just going out and trying them out. If one doesn't work, try another. Before long, they will find one that performs for them. I also tell them that what works really well for others may not work for them and vice-versa. So indeed, a great video putting that theory to work! 73 de N6VHF

    Thanks Walt. I got the same 6m pole from Decathlon here in UK few weeks ago. Cost only 20 GBP (~25 USD). Just Friday I did my first ever portable HF activity, activating my first POTA, and the pole worked great with inverted V EFHW for 40m, and higher resonant bands. I'll look to try out a vertical antenna setup next time I'm out and see what the difference is.

      @@Wilhuff_T I didn't lift the copper with the drone. What I did was lift a nylon leader cord over the limb and drop it (WD40 can as a weight) then tied a rope to the end of the cord and pulled the rope up (which becomes the anchor rope) and the other end of the rope is a 6 foot length of guy wire with teflon sleeve over it, held in place by two knots. After the guy wire, I have an insulating piece of flexible PVC hose, followed by the 14AWG copper wire. This gets pulled up over the limb by the rope manually. I hope this helps explain the process.

  • @JS-oq2cd
    @JS-oq2cd Před 4 měsíci +1

    The best HF vertical I've found was a Slim Jim. It's only good for one band but highly effective. Built from 450 ohm ladder line...a 1/4 wave matching stub connected to a half wave radiator, like a J-pole, but the Slim Jim connects both sides of the ladder line at the top and there's a gap down near the top of the 1/4 wave stub. The trickiest part is to know the exact vF of the ladder line, in order to get the dimensions right the first time. Not easy to retune. I ended up grabbing a vintage Millen grid dip meter and finding a vF of .95 when it was stated as .92. But it's worth the effort...this thing works very well on 10 meters. Built a second one for 12 meters and 2nd contact was JA with 5x6 on his end. There's also a noise benefit...it's a DC short antenna, like a loop, so has lower noise floor. Very much worth building.

    • @davidjohnson497
      @davidjohnson497 Před 3 měsíci

      Ok I think maybe that IS a J-pole, and I like the idea for 10m, it could be practical and have the low angle radiation and not require the added ground connection. Still might be good to get the bottom up at least a quarter wave above ground? Well that means the top of your 3/4 wave antenna needs to be at least 30 feet above ground. Pretty "doable"! I want to try that!

    • @JS-oq2cd
      @JS-oq2cd Před 3 měsíci

      @@davidjohnson497 This guy's calculator works well, but you need to fine tune the dimensions by getting the exact vF of the ladder line. This antenna is a PIA to retune by cutting or adding. I buy an oversize piece of LL...DXEngineering has good stuff...and short one end and use a dip meter to find the vF. Then plug that into the formula, get your dimensions, and build. The only other trick is that the 50 ohm feedpoint position tends to be just a little lower than the calculated one. I highly recommend a nanoVNA. But once you get one up and running, it's an excellent antenna. Not really sure about minimum height above as I'm using it mounted on my 3rd floor fire escape...25' above ground.

      Thanks! 1:1 balun at the antenna feed point of the antenna will keep the common mode energy out of the radio and reduce noise. Get a wire from the surface of the water to the ground side of the balun. I’m thinking you probably have a thru-hull connection somewhere that’s metal and near the waterline, just connect the wire to that. 73

    Google for OK1UFC webpage for Rybakov optimization (and many other antennas). It is in Czech, but Google translator will do.
    In short, to have good take off angle up to 10m band, the antenna shall be no longer than 6.4m. So it would be beneficial to have two rybakovs, one for lower, one for higher bands. This is the general problem with all-band antennas, that for higher bands the radiation pattern gets many lobs, not always in predictable and preferable directions.

    Why you don't try delta loop antenna? I see you have a lot of room there. 73

    If you say Rybakov 3 times, I show up in the comments, LOL. I just got a 6m pole--SOTABEAMS Carbon 6--and building a 1/4-wave for 20m is on the to-do list.

    Verticals are great in the Clear but not good in built up areas GM4NNC

    And I am sure that you install these antennas using R56 Standards!

    Bittersweet I bet being possibly the last trip. What about all your toys? You have to ship the franken-pole home. It's a legend.

    A simple 20m vertical will work the world, add a parasitic reflector and your equal to many yagis. Working vp8 from zl with 10w ssb recently. No towers or baluns etc, simple is the best. 73 zl3xdj.

    Now let's get to some math. Cut you a 80 meter 1/4 wave wire. Buy 2 inch PVC. Wrap the wire cut for 80 around the 2 inch pic. Add a stinger or whatever you need for a vertical. Now get out the old trusty swr meter or the MFJ antenna analyzer. Now cut three 33 ft ground wires. No you don't need more regardless of what you have been told. Now find the lowest swr for each band up to 80 meters. You can also get six meters. Now you may need a shunt coil on some bands to get the SWR you want. Shunts are easy to make. Very easy. This design is the same as the designs you pay hundreds of $$$$ for. And you can build it yourself. The reason this antenna has always worked well is the math. If you look at the 1/4 wave at 80 meters with a number 10 or 8 wire you will see you get a nice bandwidth . So don't use a thin wire. We need to build our own antennas in this hobby. And any of us can, with ease and patience. Just do the math . Save your $$$$$ for the next rig or amp. 73,s

    elevate the antenna 5 meters - it would much better
