    I used a mirror mount, but I made a spike from an earth rod cut in half, but cut at an angle so it was really sharp. I made radials that attach to the PL259 using a large crocodile clip. The whole spike and mount is the same length as the collapsed antenna. 73 GM4SVM

    Chuck, WONDERFUL video! I literally just recently bought the MFJ whip, the very same mount, and assembled it all on a 1.5’ copper rod. Tested it briefly out in my yard here in Kentucky about 630pm and got Italy. The way you took time to show your test & measurement results is great, THANK YOU for this commitment. I would be honored to work you on the air one day. 73!!

    Ya may want to consider swapping wing nuts for the hex nuts holding the bracket to the spike. They'll make assembly a bit quicker & easier & ya don't have a wrench to carry along on your deployments

    Ground rod clamps of the sort used for home electrical service grounding would be an easier way to secure those radials to the stake than drilling and tapping.

    Viewed again after a year. I have that antenna now... I did the same with the antenna mount, but used a landscape spike - they're right next to those stakes you used at Lowes, but about 1/3 the price. And I don't have an MPAS... 73

    You don't really need the bolt through the spike to attach ground radials, just use the bolts on the CB antenna mount.

    I have used that same method...the stake was about $2.85 at Home Depot. It ist heavy, but it's incredibly cheap and strong. No problem getting into the ground (depending on the size of the hammer). Good video!

    Hi Chuck. Great video. Thanks. I love making and experimenting with antennas. I think the only thing that 'ordinary' hams would have difficulty with is drilling a hole into the top of the stake and getting it straight, and then tapping it. I know I would find it a bit of a challenge, and I've made all sorts of DIY projects. However, if not using an MPAS device, it's not an issue. I guess the alternative method would be to use a second mirror mount and install the 3/8 stud without the plastic insulating washer. Thanks again. 73, Mike, M0MTJ

    Hi Chuck. Nice video! I made something very similar with just a 1/2" diameter 2ft. piece of aluminum from Home Depot. I bent the top 6" 90 degrees in a vice. I mounted the same mirror mount you used on that horizontal part and I use it as a handle to push the rod down in soft soil. I don't have a good way to hammer it in as in your setup, but I made mine mainly for working POTA sites that have a lake or pond. I am planning to set this up in the water at the shoreline with a couple pieces of bare wire in the water for the ground/counterpoise. I've only played with the setup in the yard so far. I'm anxious to see how QRP SSB works with a water ground plane.

    Instead of drilling and tapping the round stake for the ground radials, use a little larger crimp on terminals and put them on the bolts that hold the mount to the stake. I'd probably put four wires with Power Poles on the end. That way you could have four ground radials.

    • @KK6USYHamRadioAdventures
      @KK6USYHamRadioAdventures  2 ปีที่แล้ว +1

      I used to do it that way but like the new way better, they both work. I didn't need to tap threads and there is already holes in the stake, I just wanted 1/4" bolts.

    I bet one of the Chinese ATU-100 tuners would work on that from 40-10. I use one on a 5/8 wave 10m antenna and it takes me down to 80m. Is it efficient ? Not really. Does it work ? YES IT DOES. You ought to test it out to see what it will do on that 17' whip.

    Nice work here Chuck!
    I have a dear friend named Tom in the Middle East. A92GW Who uses the MFJ 1979 antenna on a similar type mount.
    Without ground radials, he’s contacting people here in the states, throughout Europe, Australia, Asia and has worked North Korea with it as well.
    The bonus part here, he only runs at 85 W of power.
    Antennas like this really WORK! Great video Chuck!
    I’d like to use a segment of this on my channel. I’ll be sure and credit your TH-cam channel and put a description to it as well.

    Hi Chuck, nice video, I have been using a very similar setup, I use a piece of rebar that I mount the mfj-342 onto, then the 1979 telescopic, I also use the slidewinder coil, but not always. I use a drilled n cut piece of nylon cutting board with the center drilled to fit about the 3rd telescoping bit for guying, all sets up in 2 or 3 minutes, I dont bother with radials as the rebar is conductive and driven into the ground,.. your method is a great setup as well, whats convienent is i keep the kit in my truck all the time ready to go,.. cheers n 73 !! 👌👍 I have a few videos on u tube as well under A92GW, oh n i have wanted to add a bit of wire to get 40m, but did not try that yet, but will now. All the best mate !!

    Thank you for showing me that I can do this. I have tried Ham Sticks and the Wolf River Coil and never could get the SWR to something that I could use. I don’t know still how to fool with getting the coil adjusted with adjusting the whip length. So, it appears to be forget the coil and adjust the whip length and forget the coil or not use it at all. I hope I understand this video. Thank you for your time.

    A couple of mostly successful variations on this:
    Using a similar idea, I mounted the 17’-ish whip to a chain-link fence top rail that is about 4 feet high. Electrically, that rail is about 10’ each side of the mount. These rails are oriented E-W. Then, I grabbed two 25’ ‘radials’ from a buddy-pole kit I won at auction and affixed them to the mount oriented N-S.
    Then I extended the whip to full height. I attached a 9:1 unun at the feedpoint and ran 50’ RG-58 into the shack to my antenna tuner.
    It tunes, fully extended, 80 and 20 with ease, and most other bands with a little twiddling of the tuner. 40 seems a no-go, and I have not tried 160.
    Measurements were taken with an MFJ antenna analyzer hooked to the input of the tuner.
    It performs outstanding on 20 and 75.
    Taking the other two ‘radials’ from the buddi-pole kit, I affixed them to my iMax 2000 with N-S orientation to see if it would then work effectively on 20. The feedpoint of the iMax is only about 8’ off the ground mostly due to lot and wife restrictions.
    I am happy to report that the 2000 now works much better ON 20 m, and seems to work better on 10, 12 and 15. Non-scientific eval!
    Keep up the fantastic work!

    I stick a T post in the ground, mount my 18ft aluminum vertical on it ( no loading coils) slap a 9:1 unun on it Maybe a couple of ground radials ( not always needed but they will help) And hook up my radio with it's internal tuner and work 80 through 6 meters. If a tree is available, throw a wire up in the tree, quick easy and cheaper. And alot less complicated. Neat ideas you have but time consuming and costly.

    Good and interesting video. I have the Wolf River Coil and want to get the 17'whip for it. I also see you have a link to a Bluetti power station and I have one as well. Have you used this as a portable power supply for your ham radio while out in the field? If so, how did you utilize it. Did you take the power supply as well and plug that into the Bluetti and then plug the radio into the power supply? Or can you find or make a connection and plug the radio directly into a DC outlet on the Bluetti? There is no problem with the radio rated at 13.8 V or the radio drawing too much current?
    Thanks!

Works great the nail holds well and it's easy to get into the ground. 40-6 meters does very well. Maybe the nail is for putting land scape timbers together I can't remember.

    I find anderson powerpoles connectors too expensive... I usually use nice and cheap bullet connectors. I make sure to put the female part on top to droop down and plug in the (male) radials into them. if someone trips over one there should be enough force to disconnect them. I like to solder and heatshrink all the connections to give extra rigidity to the connectors.

    I want to see the contacts you make and see the ranges you get. Getting a good SWR is one thing but getting bandwidth and range is another. A practical use with a map and pushpins to show where you made your contacts would be great to show hams if this meets their needs. Nobody needs another substandard antenna in their pile of mistakes and misfits.

    • @KK6USYHamRadioAdventures
      @KK6USYHamRadioAdventures  2 ปีที่แล้ว +1

      FlyBaby, I will post a video for you that I made 85 contacts in about 60 minutes with the stake and the 17' extendable whip and see if I can find the log info to get a pushpin map. The video was a POTA activation running 100 watts on battery power. I was in northern California and a lot of the contacts were to the east coast and one into France not too bad. Your right SWR means nothing if the antenna doesn't work, but as you know a 1/4 wave vertical is a great antenna just think DX Commander. I assure you this is not a substandard antenna and try not to bring those type of antennas as a suggestion for the viewers.
