    I've modified mine a bit. I've swapped out the standard whip with a foldable whip, I got off Amazon, that's a bit longer and doesn't run the risk of jamming or breaking. I've also marked off my radials off for the various bands. I have additional, marked radials if needed. It does work really well

      I've used the Chameleon mil-whip and mil-extension with the WRC. When you combine both the mil-whip and extension, the collar is almost to the top of the coil for the 40m. Makes for a powerhouse antenna on that band.

    Another great video, I just purchase a Wolf River Coil ( same model as you ) and the best I could get was 1.8 . After watching your video I was able to get it below 1.5 across the band ! Thank you Michael you saved the day LOL .

    I own 2 Silver Bullet 1000 and two TIA's. I find the antenna absolutely impressive and pretty weather proof - even here in Alaska where I've left it outside all winter. I spent about a full month experimenting with the number of radials required for each band and Yes... you are correct. 3 radials works good on all the bands. 4 radials is better but not by that much and 5 radials etc... I've made almost 3,000 contacts using the Wolf River systm. Nice to see they manufactured a Hi-powered Platinum version. I would love to have a 160m version. They had suggested but..... AND, thanks for the tip on the Chameleon antenna. i'll definitely order one shortly. GREAT video Michael /Dan KL1JP (Alaska).

      I've left my WRC set up all winter in the back yard, it has good weather resistance as long as you use some antioxidant on the screw connections. I did talk to the WRC guys during a hamfest meetup about a 160m version. They feel it would be very compromised and the bandwidth would be paper thin. But I have heard of people experimenting with it on that band, so if you are up to the challenge . . .

    Usually ground mounted radials don’t need to be tuned by band. Raised radials do. The quantity can affect it but usually not length. I always use 3 at 33’ for all bands and get an acceptable match.

    • @KB9VBRAntennas
      @KB9VBRAntennas  2 ปีที่แล้ว

      I know that's a popular thought and the way it should be, but I've also run into a 'brick wall' while adjusting for a good tune on the higher bands and often shortening the radials drops the SWR right down. There are a lot of variables at play and I wonder if ground conductivity plays a role in radial performance.

    Hi Michael.. I just finished a trip to CA/OR/WA. I activated about 60 or so, new to me , parks. One must be similar to your Ice Age Trail.. The one here in MT, ID and OR probably happened at the same time.. The one out here is called the Ice Age Flood NGT. This flood had huge boulders encapsulated in ice and dropped them on top of some pretty high hills. They are called Erratic Rocks and can be found all over the area where the flood happened.

      The Ice Age Flood trail is similar to the Ice Age trail in that these events happened in the same era. The Ice trail marks the extent of glaciation in Wisconsin while the Flood trail is the remnants of the catastrophic flood that happened with the glacial meltoff. The Ice Age trail is littered with erratics and its one way to mark its location, in addition to moraines and glacial till.

    Hey Michael. I have the same whip and coil. The whip is resonant across the 20m band without the coil when fully extended (and with plenty of radials). Maybe a quicker tune on 20m would be to just remove the coil. Thanks for all of your great videos.

    Also, if you have rocky soil or there are boulders around raise it 3 to 5 feet off the ground.

    Hey Michael- thanks for all the informative videos- I am trying to decide between the WRC and the Gabil - I need information on 80 meter performance in addition to what you have provided for 40 and up for a comparison between the two products. Any chance you have tried either or both on 80? thanks- Fred K4AFV.

    • @KB9VBRAntennas
      @KB9VBRAntennas  11 หลายเดือนก่อน +1

      I don't have any personal experience with the Gabil antenna, I may have to pick one up and test it out. But I can comment from my experience running 80 meters on a vertical like the Wolf River Coil. The two biggest issues when it comes to 80 meters with a vertical antenna is bandwidth and efficiency. With the WRC, your bandwidth is pretty tight, usually around 50-60 KHz. The determining factor on that is the diameter of the coil, narrower coils will have a higher Q and less bandwidth. To get the most bandwidth out of an 80 meter vertical, look for one that has the widest diameter coil.
      The 2nd issue is efficiency. The more coil you use, the less efficient the antenna will be. More power will be spent warming the coil section than radiating from the whip. In order to combat this, you will want the longest whip possible so you can use the least amount of coil. I've used my Silver Bullet 1000 on 80 meters with both an 102 inch rigid whip and the 213 inch collapsible whip. The performance is much better with the longer whip.
      80 meter portable operating can be a challenge. Unless you are in the winter months, the bands can be quite noisy and the antennas are quite long. I usually only run the data modes on 80m in the summer months, but by late October the band settles down enough to enjoy 80 meter phone at night. I hope this gives you some help in making a decision.

      My method is a little over the top because I need clean audio for the video, but briefly, I am using the Rode Wireless Go 2 lavalier set. This allows me to record two channels of audio. One unit is plugged into the audio out jack in the back of transceiver and the other unit is clipped to me for my voice. The receiver on the camera puts the two channels into right and left stereo for the video. When I edit, I mix the two channels together and adjust the levels for good sound. I'll do a video on the process for those more interested in it.

    Do you ever add an in-line choke to your setup. If so, where do you place it. At the antenna or at the rig. Going back and forth as to if it is really needed

    • @KB9VBRAntennas
      @KB9VBRAntennas  2 ปีที่แล้ว +2

      My long coax has an integrated choke, but I don't think it's necessary for the Wolf River Coil as that type of antenna typically doesn't pass common mode currents down the feed line. Any choke would be placed near the feed point of the antenna for maximum effect.

    Would having the radials running over concrete vs soil/grass affect the SWR?

    • @KB9VBRAntennas
      @KB9VBRAntennas  2 ปีที่แล้ว

      It does, and ground conductivity is one of the variables in getting a good match. I often will stretch the radials out to what I think is a good distance, adjust the whip and collar to the lowest SWR that I can (which in some instances may only be 2:1), and then adjust the radials to get that final good match.

    I know elevating the coil a bit is supposed to help, but is it worth the effort?

    • @KB9VBRAntennas
      @KB9VBRAntennas  6 หลายเดือนก่อน

      That's a good question. From a setup standpoint, ground radials are faster and work quite well. I believe the advantage of an elevated radials is it's independence from ground conductivity effects. If you have poor ground, the elevated radial may be worth the effort. Maybe when it gets warmer, I can test that hypothesis.

    • @KB9VBRAntennas
      @KB9VBRAntennas  2 ปีที่แล้ว

      If you are hearing a buzzsaw noise, that may be manmade or electrical interference. But noise on 40 meters has been slowly increasing. Part of that is the seasonal atmospheric change, but the increasing solar activity also plays a big a part.

  • @davewhite7679

    It's a good option to have in your bag, but for 14 MHz and higher I'm not a fan of that "fiddly" tapped coil and variable telescopic whip lengths, etc... I think single band Shark sticks are faster to setup and teardown, simpler to change bands, and will get comparable results. Just my opinion. 🙂

    • @andrewhamop6665
      @andrewhamop6665 2 ปีที่แล้ว

      Just a friendly FYI, the Wolf River coil doesn't use any traps or capacitor matching. Just think of it as the variable inductor inside a manual antenna tuner, except in this case it's not being combined with a capacitor to match the impedance to your radio. When you have under a 1.5:1 SWR on a WRC, your antenna is more or less perfectly tuned for the frequency you're using, no impedance matching or anything. In other words all of the power you are putting out of your radio, minus the coax losses will be making it to the antenna.
      I love my Silver bullet 1000, and have not yet experienced any melting or deforming due to high power. I typically run 40 watts of digital / 100w SSB, and could get away with much more on 20 meters and above because I have center loaded my coil and I'm barely using any of it for the higher bands. However above 40 meters be mindful of your coil temperature, my coil nearly reached melting temperature when I was running a hundred watts of WinLink on 80 meters.

    • @KB9VBRAntennas
      @KB9VBRAntennas  2 ปีที่แล้ว

      One advantage of the WRC is that it gives you a higher Q or quality factor compared to the sticks. I will totally agree on the faster setup and teardown of the shark sticks. I'll have to do an A/B comparison of the two antennas.

      @@KB9VBRAntennas Yes, a performance comparison between those 2 would be revealing. From 14 MHz and up, those vertical Shark sticks are amazingly effective. Plenty of bandwidth too. When an Italian station responds to your SSB "CQ" you know it must be working. 🤣

    Do the radials need to be tuned? I was under the assumption that if they were at least 1/4 they would be ok. But longer would be better?
    Second, should the coil be as close to ground as possible for takeoff angle. Or would raising the coil/antenna be better? I tried both and saw no difference in my testing.

    • @KB9VBRAntennas
      @KB9VBRAntennas  ปีที่แล้ว

      Radials laying on the ground don't need to be tune, but I've found that length still does have an effect- especially if you are using a small number of radials. If the radials are elevated, they do need to be tuned to the frequency to be effective.
      I believe keeping the coil as low to the ground as possible is supposed to give you the best, or lowest, take off angle.
