What an ambitious, fantastic day of park activations ! All three antennas are in my kit, and I can't pick one as a favorite over the others, as they all work so well. As you demonstrated, Michael ! Thanks for a most entertaining ride-along. W3WJ.
Thanks for the reminder of the fun of working a pile. You added contacts on fifteen, my fav portable band. I'm sure I haven't had any all year. Good stuff!
Not so much during the summer months, but I’ve had some great success on 15 meters from October through April. I’m looking forward to another exciting winter on that band
I love it when you make a contact into Europe and then then they spot you, all of a sudden it's nothing but europeans which gets confusing quick with the different prefixes. A lot of fun. Thanks for the great video like always!! Vertical seemed quickest and easiest to get on the air.
Awesome! Last year, I did a 5-park rove, using 5 different antennas, and just 5 watts, for International QRP Day. It was a good challenge and a lot of fun.
It's a pleasure to have made your video! My inverted V was strung East to West. I'm surprised to hear you had the loop East to West as well. 73 de W8ZFM
Loops pick up best along their broadside, but they also tend to have a bit of a shorter skip. I think that's why I got so many lower midwest stations on 20 meters that day.
I like all the DX you had with the EFHW and surprised that the vertical didn't get more DX, probably time of day. The vertical has worked well for me in the past as well. I might have to send you our new multiband vertical tp see how it compares. I spent about 4 hours today test two versions, basically different toroid's I think people will be surprised at the outcome. Nice Job Michael, 73!
I think it was partially time of day (it was about 22:00z) when I was on the air, but also the pileups were so large, I'd have a hard time hearing the weaker European stations.
Outstanding job on your activations . it's hard to pick a favorite antenna since you had such great results, but it's nice to have them all in all in the tool box. - Thanks for another great video.
Wow!! Great video. I liked the loop and vertical antennas. Mainly due to the ease of deployment. But you proved all three antennas did a good job. -KE6EX Algonquin IL
A very rewarding day for you and certainly motivational to get out to POTA! The vertical was simple but very impressive and I'm going to add it to my bag for quick and easy activations. Thanks for another very informative video Michael!
For portable activations there is also the difference in how much work setting up one antenna over the other is. With an endfed or other wire antennas there is the throwing which for me usually takes multiple attempts. With a vertical there are radials or the magic carpet. Thanks for making this video!
The vertical with the screen is the fastest to set up and tear down. I can be on the air in minutes, that's with adjusting the whip to resonance. The end fed takes about 10-15 minutes to set up and about 7-10 minutes to tear down. The advantage of the end fed antenna is that band changes are effortless. I don't have to disconnect the coax, adjust the antenna, test, and reconnect. The magnetic loop is some where in the middle: fast setup, but more time spent tuning for a frequency. If I know I'm going to be on one or two bands, or only out for an hour or so, I'll use the vertical. If its a day long or weekend ordeal, then I will take the time to put a wire antenna up.
Congrats on #100 Michael! I myself have committed to the 213” Vertical for my 20-10m activations using 6-16 1/2’ radials. Looks like you did well, check that very well with the vertical also. Thanks for the video(s) and GL. 73 Randy N5ilq.
I enjoyed this video very much. Well made and interesting video sir. I'm brand-new in HAM, don't know anything yet. But that POTA stuff looks real interesting. I think I'll be building the long-wire dipole next.
Hey Michael, always love your videos mate. I would say the vertical is my choice, especially that time of the day on 20 meters - grey line madness! Cheers!
My favorite would be the EFHW as it makes for easy band changes. Next would be the 17’ vertical with one or two elevated counterpoise(s). I don’t have a mag loop because they’re too expensive. Congratulations on your 100th party Michael!🎉
The quick band changes with out readjustment do make up for the extra time it takes to set up the EFHW. If I'm going to sit at a park and work down the bands, that's the route I'd go.

Some crazy pileups. I’m glad my parks have been a little more calm! I’ve been using the magic carpet on a WRC. I’ll try to get you from a park so we can get a carpet to carpet contact. LOL.
Late afternoon on a Saturday is going to do that, especially on 20 meters. Another good time for massive pileups is a Saturday evening late shift on 40 meters.
My Coffee and Ham Radios Artemis (brother to the Apollo) is my Every Day antenna. Maybe I'll be good enough some day that Santa will bring me a WRC Sporty 40 and a whip. U-rah-rah
EFHW are always great. QRN, and mayhap band QRM, but the bands that are possible are amazing. Magloops are becoming a new 73 of mine as they are also NVIS. Verticals always work but can be limited to bands. My 73 of this video was the magloop. KF0NNQ.
Great video! I'm getting closer to buying my first HF rig (probably an FT-891 as well) and doing some POTA/SOTA stuff, and videos like this are so helpful in getting my callsign ears in shape. I'm a bit scared that I'll be very slow at recognizing callsigns and hope I improve quickly with practice, which I'm sure I will. Love the editing with all the different calls, back to back, and I doubt that you're asking permission to use the calls on your videos right? No need really, I would think, since it's all wide open anyway, but I am curious.
There are things you can do to manage the pile-up so it isn't as massive as this. I did a video a couple years ago on a couple strategies: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wHMij1JrT64.html. As for recording, since the airwaves are public, there isn't an expectation of privacy. Permission wouldn't need to be granted for someone voluntarily calling me.
That ever elusive "BEST" portable antenna. 😂 Based on what criteria? Bandwidth, portability, take off angle, ease of deployment, directional gain, noise rejection, impedence match, multi-band agility, weight, footprint requirement, wind resistance, cost, etc... Every application and every deployment location is unique. So any singular "BEST" antenna is a fantasy. 😅 KZ9V
@KB9VBRAntennas Exactly right! Do you remember the old "light bulb antenna" contest? 😂 Some of us have even accidentally made a contact while still connected to our test dummy load. 🤣 KZ9V
The 3 antenna comparisons was awesome. I have to say I enjoyed the vertical with the Magic carpet and the F-loop. What length of LMR cable did you use with the F-loop? Did you have a 3 or 4 foot loop. I just ordered the CHA F-loop DIY kit. I’m looking forward to building it and trying it out. Bill, KC2KNA
I used the standard 3 foot loop (102 inch length) on the F-Loop 3. I think the DIY kit is a great option for getting a magnetic loop at an affordable price. Have fun building it.
Hi Mike! I'm wondering 🤔, Could I use 3 poles of a dining-fly to support a long-wire dipole antenna? If I'm free of buildings does it really have to be very high off the ground? Yours in the park wasn't. Next! I gotta understand how long. I'm studying, just going slow. Thank you for your time and videos. John O
The peak of my wire antenna was at about 20 feet and sloped downwards to about six feet. The general rule for dipole antenna height is that you will have an optimized RF takeoff antenna when it is 1/2 wave in the air. Below that height, the lopes start to point upwards until you get to the point that they are radiating directly up. This concept is called Near Vertical Incidence Skywave (NVIS) propagation and is very helpful on the lower bands (40 meters and below) for making local or regional contacts up to about 250-300 miles. On the higher bands, 20 meters and above, NVIS doesn't really apply, as the lobes will pretty much radiate outwards at any height. With the antenna about 20 feet in the air, I should get good stateside coverage on the 20 meter band, which was my intention. Now to answer your question, the poles from a dining fly are going to be very short, probably under 10 feet. You can support a wire antenna with them, but don't expect DX or international contacts. On 40 meters or less, your antenna will act as an NVIS antenna and give you good regional coverage. On 20 meters or higher, you will probably be limited to about 1,000 - 1,500 miles or so. For portable operation, I'm pretty happy if I can get the antenna up 20-30 feet in the air. At that height I can talk anywhere in the US with a bit of DX or international contacts if propagation is willing.
Both the screen and the cloth provide the same performance so I usually pick one over the other for mechanical reasons. This time of year it can be windy and the ground muddy. I've found the screen 'sticks' to the ground better in the wind and I don't worry so much about it getting dirty.
The CaHR end fed antenna includes about 90 feet of wire. You use about 62-67 feet for the radiator and the balance (about 23 feet) can be used as the counterpoise.
I ran 50 watts on the end fed and the vertical and 20 watts for the mag loop. The magnetic loop is limited to 25 watts sideband due to the air gap capacitor in the tuning unit.
Nice work Michael. I always find it unnaturally weird to sit in any other seat other than the driver's seat in my own car. I know there is just more room sitting in the other seats and I see many do so... But to each their own. That CARH antenna did pretty darn good with the DX. 73!
Yeah, I suppose I could put the seat back so I'd have more room behind the wheel, but then I'd have to readjust it when I'm done to once again find that perfect spot for my foot to hit the clutch.
I tried building the 9:1 UnUn you demonstrated some time ago. I crossed the antenna connection and ground with a 460-ohm resistor because it was what I had. The SWR's were so high they would read on my RigExpert AA230 zoom. I checked to make sure I had wired it correctly and I had. To be sure, I built a second one with the same results. I did use 3 240--43 and 14 gauge magnet wire on both builds. Do you have any recommendations on something to check or an idea of what I may have done wrong? Thank You and I appreciate your videos and your help.
The first thing to me that comes to mind is that there is a dead short somewhere in your transformer. That would be the only way to explain why the SWR would be off the scale when testing with a resistor. When I wind a transformer, I'll use a continuity meter to verify and label each end of the wire as A, B, or C, so that I don't mix up wires as I solder them together. The only other explanation would be that your ferrite core material isn't truly 240-43. Depending on were you got it from, it may have been mislabeled.
Thanks very much for your response. I checked. I did check for shorts before making the connections. I am not sure about the toroid, I got it from Amazon and I ordered a 240-43 but to my knowledge there is no way I can check to that is exactly what I got.
I did a google search for the term "how to identify unknown toroids" and got some resources on how to check the initial impedance and permeability of a ferrite core. This may be helpful in identifying your toroid.
Thanks Mike. I like the Wolf River Coil and Magic carpet since it is what I use. I also have 3 band linked vertical (17m, 20m, 40m (Don Dickey special)) wire that I toss into the tree. 73, Stu, K8STU
Which antenna did I prefer? I am always partial to the vertical with the magic carpet. You can have that up and running in just a couple minutes and don't have to worry about finding trees or setting up poles to attach wires too. Awesome video as always.
It's good to hear you are getting out to parks. 20 meters was so congested that morning that I don't think I would have heard you unless you had a big signal.
