    Hey Michael! As always, a wonderful video with a Polish-American history lesson, too! And thanks once again for featuring the PERformer quarterwave with elevated radials in one of your videos. It's fun to see in action by other operators. One of the best features of the PERformer is its radiation efficiency being over 90% (meaning 100 watts in, 90+ watts out) and you demonstrated that in your activation. I appreciate you continuing to keep the PERformer active in your antenna arsenal. Keep in touch my friend 😀73 KJ6ER

    Thank you Michael. I did an activation, today, using an MFJ 1979, 17' whip on a Gabil tripod, with BOTH faraday cloth and 5 17' counterpoise speaker wire ground radials. It worked great! SWR almost flat across the 20m band and super contacts. I get a lot of my ideas from you and your content. Keep it coming. 73

    I follow you and I think I have seen nearly all of your videos. It has been a long time I have though of doing Ham but never pulled the trigger. You have steered me toward and away from various products some good and some not so good. I am about to start up some video posting then eventually streaming. I do enjoy this hobby that kinda is becoming a mild profession now that I am retired all together. Eventually somewhere down the log I would like to meet up at an RV park. I doubt it would be within the next year. I live in Alaska and will make a long trip down to Ohio again within the next two years so doing a meet and greet would be super awesome.

    When the weather starts getting cold, it's multi-band antenna season for me, so the Rybakov would be my pick. Set it up once and then stay warm in the car or shelter with the ability to change bands at the push of a button.

    The performer does have a 3dBi “front to back”, at its best direction it’s 1.5dBi up on a quarter wave with 2 elevated radials at 180 degrees at the same height and is 1.5dBi down at its worst direction. The Rybakov also does not need that many radials (hardly any) from 10-17m as on these bands it’s between a 3/4 and 1/2 wave approx. It’s only from 20m and below that radials become important.

      The Rybakov really screams on 10-15m. Last month I did an activation on 15 meters and over half of my contacts where European stations. (it helps when the band is open, too). But setup was a bit more of a hassle for that antenna. that is, until Chameleon introduced their 25 foot whip. Now, according to my estimation, I can set up either antenna in about the same amount of time.

    Michael, another great video. I see that you are not using the jaw mount clamp on this setup. I also use a mirror mount on my flag/banner stand. Once I bolted it on, I just left it mounted to the stand. I also see that you are using four ground radials. How long are they? I use six ground radials that are 16-1/2 feet long. What was your swr with the four? I really enjoy the rybakov antenna. 73s

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา +1

      I don't use the jaw clamp with the 25 foot Chameleon whip, because I've found that when fully extended, the clamp starts to slip, making the antenna lean. The four ground radials about about 16 feet long. This is the preferred length for the Rybakov. On 20 meters the Rybakov SWR was 3:1, so the tuner had no problem finishing the job.

  • @DEKINDY6065
    @DEKINDY6065 21 วันที่ผ่านมา +2

    Can't beat the POTA Performer for performance and simplicity of equipment required and ease of setup and takedown. Only negative is time required to switch bands compared to the Rybokov.
    If I wanted to hunt a lot of bands and work on the N1CC I might prefer the Rybokov for a period of time to do 10 parks. Again, for simplicity and ease of setup and takedown, I would use a nonresonant end fed wire antenna that the rig's internal tuner could handle multiple bands over the Rybokov. Chameleon and Palomar Engineers offer great multiband end fed that can be handled with an internal tuner.
    The Rybokov is a great base antenna. Permanent installation and ease of changing bands make it a winner as a base antenna. I just cannot see hauling an external tuner around for POTA.; prefer the FT-991a shack in a box with internal tuner over the FT-891 HF and an external tuner.

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา +1

      For N1CC hunting, I'll set up a 71' end fed random wire antenna while camping and work all those bands over the weekend. But for my last 10 band activation, I used the Rybakov. You can improve the low band performance by adding a 28 foot long horizontal wire off the top of the Chameleon 25 foot whip, turning it into a 53 foot inverted L antenna. I show you how in this video: th-cam.com/video/i1RDLy7a0ZA/w-d-xo.html

    Hey Michael, another great video. It’s always fun to hear when we make a QSO with you. I did the North Dakota POTA day last weekend and it was pretty fun. I was able to make almost 900 contacts in seven hours at 4 parks. I was using the VOX feature, which is new to me, but a game changer. I noticed you were still using a switch, have you considered using VOX? 73, WI0O

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา

      I don't use the VOX as I'm afraid of background noise. But I'm thinking of switching up to the foot pedal for high rate mobile events, like the WI and MN QSO parties. 900 QSOs in 7 seven hours is a great rate. I almost hit that level on the Wisconsin QSO party, but the setup and teardowns between parks almost killed us. We may have to swap tips.

  • @dsharaf
    @dsharaf 21 วันที่ผ่านมา +2

    What Fun! 😀
    Instead of hitting 2 parks at different times of day, would it not be better to set up both antennas in the same park and use an A/B switch alternating antennas every 10 contacts? I would think that this would give you a better way to compare the two, wouldn't it?

    • @truckinguy92
      @truckinguy92 21 วันที่ผ่านมา

      I was thinking the same thing. You really can’t compare 2 antennas performance without doing a side by side comparison. Other than that, another great video.

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา

      The only way to legitimately compare the two antennas would be side by side WSPR testing alternating between the two with every cycle. Once I have the pileup established, the pileup will continue no matter what antenna I'm one.
      I'm glad you enjoyed the video. I like producing this style of entertaining content, because as hams we tend to really get bogged down in the numbers and really miss the enjoyment of amateur radio.

    • @truckinguy92
      @truckinguy92 21 วันที่ผ่านมา

      @ that’s not the only way to test 2 antennas. When I want to compare 2 antennas, I do it 1 of 2 ways. 1) I send automated CW test messages, 3 minutes on 1 antenna, & 3 minutes on the other. Then look at the RBN Reverse Beacon Network filtering down to 3 minutes. This is my easier method and more in line with where my SSB signal would be heard. WSPR works as well but requires more setup and with me being anti digital doing it with CW is more in line with my beliefs of what ham radio is. 2) Actually ask the hunters to compare the two signals as I use my KXPA100 which has 2 antenna ports to switch between the 2 antennas. This also allows me as you call it “not get bogged down by the numbers”. I actually get to have a little bit of a QSO with hunters as well, which is a nice added bonus. POTA isn’t only about the numbers after all.

      @KB9VBRAntennas  20 วันที่ผ่านมา +1

      For the last couple months I've been running the POTA PERformer antenna and the longer Chameleon 25 foot whip because the upper bands, notably 15 and 10 meters have been really hot. I typically don't use a coil on those bands. But with winter approaching, I'll get into more low band stuff and the Big Kansas Coil will certainly go back into the antenna rotation.

    With the elevated vertical have you seen any need or benefit from having more than 2 radials, and do you try to angle them at 45 degrees for a better ohm match, or has it really needed it?

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา

      Angling the radials downwards does improve SWR slightly. Honestly, if I am in the ballpark of 1.3:1 or less, I don't sweat it. The reactance is typically near zero anyway, so I'll run with it instead of trying to get perfect SWR.

    • @scubasky
      @scubasky 21 วันที่ผ่านมา

      @ do you think adding 2 more radials would be a benefit to rounding out the signal in all directions? What about 2 radials for 20m then place 2 radials for 10m then with a tuner you could do 20-15-10 without changing radials but adjusting the whip only?

    • @KB9VBRAntennas
      @KB9VBRAntennas  21 วันที่ผ่านมา +1

      Two radials at 180 degrees is enough to give you omnidirectional coverage. Four radials is the sweet spot for antenna gain, as adding more above that number only gives marginal improvement: rudys.typepad.com/files/qst-march-2010-ground-systems.pdf
      The problem with adding more radials is that it also adds to the time it takes to tune and adjust the antenna for a band change. For portable use, in the trade off between time and efficiency, time wins out.
      As for using varying sized radials and adjusting the whip, I don't have an answer. That would be something that would need to be modeled and or tested. But it is a good theory worth trying out.

    • @KB9VBRAntennas
      @KB9VBRAntennas  20 วันที่ผ่านมา

      With a tuner the Rybakov will work on 10-80 meters. But it is most effective on the upper bands, 10, 12, and 15 meters. That's because on those bands it develops a major lobe with a low RF radiation takeoff angle that is excellent for DX.
