Ordered the Dually. Thanks Walt

[@KG6UQA]

Looks like a fun antenna project to build, have to look into one of those kits

[@GoAmateurRadio]

Walt, thanks for activating Rocky Point. While visiting family, I went there as a kid . Nate W4NDK

[@corsavic1]

Walt as many have said great vid and location....this is the way of the ham

[@DonDegidio]

Hi Walt, Received the HamAlert when you were at W1 and was listening, but didn't hear you. The G90 probably would load that swing support tower. Steve K5ATA once connected his G90 to a handrail on a dock during a POTA in MS. Stay safe. 73 WJ3U

[@angelscomputers]

I love it, “hey, there is a steel structure, let’s tune it with the G90” lol

[@tinysolarshack9615]

I seriously hope you try both unun’s and see if you can load that tower. I suspect a couple counter poise wire to capacitively balance it and it could be a ton of fun.

[@paulsengupta971]

I think you should try the 9:1 on that cable car thing. That looks like a great antenna...

[@northwoodsyankee3528]

Cool. Yep, as soon as I saw that tower I thought, "He's gonna try to load that thing up."

[@redstickham6394]

That would have been interesting to say the least. I've heard of loading up stuff like bedsprings, ladders, metal rain gutters, even curtain rods, just to see how they will perform and what can be worked.

[@northwoodsyankee3528]

@@redstickham6394 Ya never know til ya try!

[@wildbill1]

Wow, what a cool transformer a 9 to 1 and a 49 to 1

[@hughpatterson1480]

Great video Walt! Thank you! I had just purchased a project case big enough to enclose two Ununs, with this very idea in mind. I wondered if you could do this and saw the Dually. I think I'm going to build a baffle between the two Toroids to be on the safe side. I know the band conditions have been crazy, being great one moment and falling apart five minutes later. Such is the way during Solar Cycle 25. It was great to see the Dually in action and will eventually buy one. Have the two mounted together is a brilliant idea. As always, I enjoyed this video. I was on the 10 meter band the other day and SImon HamJazz was live but the band started to fade rapidly when I tried to make contact. This type of problem makes amateur radio a little more exciting because when you do make a contact, under sketchy band conditions, you feel like you've pulled a fast on propagation. Thanks again...73...Hugh...KN6KNB

@@hughpatterson1480 thanks Hugh!

[@MikeN2MAK]

That looks cool! I'll have to check it out. The 29' random wire is always fantastic.

[@Retired_Five-0_W4WAG]

Nice video as usual at a Great Location! Can’t wait till the next video, when Salty Walt Lights up the Tower! 💥 🎇

[@hazer72]

Is that clear shrink wrap? Looks like a cool kit! Looking forward to the tower antenna! :D

[@rossbassette7518]

Walt, You could try building a linked radiator which would allow you to change from a EFHW to EFRW without taking the wire off your mast. I really like the idea of this UNUN and might just have to give it a try. Good Job, Ross, K8RLB

[@markhyman359]

Another great video, Walt! What kind of ground mounting system did you use with that DX Commander mast?

[@robertmeyer4744]

That was great fun. love that kit. 2 UNUN on 1 board. I just saved it. I got the ten tenna 49:1 /56:1/64 :1 switchable one saved as well. bands weird and in Boston NY we got record heat and super HUMID. power staying on. was down to 110V doing 115V now. normally around 121 V hear. Rode Island is hard for me. some times 40/80 meter NVIS I get on FT8 . nice clear heat shrink. 73's

[@K2DXK]

Sorry I just saw this. I would have liked to get you in the log book. I’m on the north shore of Long Island. Are you in New England any longer or heading back home? 73 John K2DXK. PS I added you to ham alert

[@NateDaniels86]

Hi Walt I have been enjoying your videos for some time I built the 29ft vertical with the 9:1 today in my little garden in England works a charm seems to be outperforming the sigma360 much quieter all the best

[@captainwyattoutdoors1636]

Fantastic video. I love the background you give on the location. Keep it up!

[@Philip-KA4KOE]

If the tower is grounded try a shunt feed if practical

[@johnnorth9355]

Now you are getting into Kevin's territory clipping your G90 onto big bits of metal ! Looks like multiple opportunities in that abandoned park ? 73 M7BLC

[@jeff-73]

Interesting design. I wonder if there is a way to test if there is interference stacking the toroids like that.

[@dbailey3024]

efhw rule or a tuned vertical u loose less power qrp i use both types and a magloop depending on where i go i find 9:1 is not as efficient

[@DarkShadowCustoms]

I am confident that the G90 will tune that tower right up. You just have to figure out how to connect it to the radio.

[@DaDitDa]

For random wire antennas, a switchable 1:1 (i.e., direct connect), 4:1 and 9:1 UNUN would be a handy device.

[@tommycheshire5508]

There is a lot of sailing that goes on that bay in the spring and fall, big boats!

[@W4TRI]

Was considering a couple of 9:1 kits. Could not get this paid for fast enough! I do hope he offers a built version later.

[@cornbread-KO5RN]

Walt. 👋😎is this the none member section 😂

[@WECB640]

What a perfect location! The "Dually" is a great idea and hats off to K4QCD for making them. Thanks Walt for sharing some of the history on Rocky Point. We had a ton of amusement parks here in New England after WWII, and they're just about all gone now. PS. Can't wait to see how the tower loads up. It appears to be grounded, so a shunt feed would be best. Try it anyway! Every conductor will radiate and this will be a fantastic experiment. 73 OM 👍

[@COASTALWAVESWIRES]

It was great and I’m so glad I found this spot. There are concrete footing pads at all four corners of the tower that might actually help me out. We will see very soon. 73 my friend!

[@abdennourbouras6243]

Hey Walt , that dual UNUN end fed antenna seems like brillant Idea ...What is the maximum PEP power that this end-fed antenna can handle?

[@KO4GBB-Moe]

Awesome

[@wyominglife3202]

Can someone explain why he adds /W1?

[@blugoose86]

Somehow I missed the notification on this video, so I'm glad you mentioned it in this mornings episode. What a great idea. I just happened to have two toroid's sitting in a box waiting for an assignment. Fantastic video and what a beautiful park. Thanks as always Walt for another great, informative video. Honestly, you keep me going in this hobby. 73 de KA9TII

[@k2jwd]

Enjoyed the video. That tall tower is probably grounded . Good luck with using it as an antenna :( Mel, K2JWD

[@truckinguy92]

The /W1 is no longer required to be added to your callsign. The bands are wonky? You just made contacts with SD & WA using 20w. How does that make them wonky?

[@COASTALWAVESWIRES]

I’m doing it because I have a separate log for up here. I probably won’t use it all the time but I like separating my contacts out by location and using /W1 is completely acceptable. The band had horrible QSB, you could hear someone for a minute and then completely loose them. That’s what I meant by wonky.

[@DarkShadowCustoms]

@@COASTALWAVESWIRES I was thinking the same thing truckinguy92 mentioned, but I can understand using the /W1 designation if you are using a separate log for that area. Make sure you add that /W1 as an additional callsign on your POTA account. Hopefully the park to park contacts included the /W1 when they logged you. A good reminder for folks to log what they hear.

[@bevo65]

Dude, I saw you pop up on PSK reporter and tuned in and listened on 20 meters. No joy here in Central Texas. Next time!

[@kennethblackwell1137]

Thanks Walt....the Dually looks like a good contender.

[@acestudioscouk-Ace-G0ACE]

Thanks for the video, an interesting and useful product. Makes you wonder why no-one has done this before.

[@leosmith4287]

Rocky point is a great park just 15 minutes from my house. If you’d like to do a meet up, or meet at a park let me know.

[@fransahm1956]

What is the Whiskey One designation? I dug around and found no info.

[@Sabre2165]

That indicates that he's operating from Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, or Vermont.

[@dadthejedi]

@@Sabre2165 New ham here...are we supposed to use a different call sign for different areas within the US? I haven't seen that mentioned anywhere other than for outside the US.

[@Sabre2165]

@@dadthejedi There is no legal requirement to do this within the US. It used to be that, if you moved to a different region of the US, you had to have a new call sign to identify where you live. That rule is gone, but many operators add a location code to indicate where they're actually operating from if other than where they live. For example, if you have callsign W1W and you're operating while on vacation in Hawaii, you might call yourself KH6/W1W or you might say "W1W stroke KH6." This quickly lets others know that they're making a contact with someone in Hawaii.

[@COASTALWAVESWIRES]

Correct, I only do it because I’m logging it that way in QRZ so I can keep a correct record of my contacts while I’m here. Thanks for explaining. 73, Walt

[@moselblues8694]

nice design! Like the idea 🙂 73 de Jan, DG1JAN

Yes, bartender, I'd like a G-90, on the rocks...

[@georgebradshaw474]

Hi Walt, looks like a beautiful day there for your first activation. Not sure of the “/W1” designation after your call? Have fun and keep the videos coming, thanks. ‘73. AC3EA

[@frankmccormick5766]

My question exactly. Researching suffixes today.

[@dorvinion]

Whiskey one represents the ARRL call area that he's operating out of. New England is whiskey one, Southeast is whiskey 4. You can find a map of the sections if you really want. It's not required to use them, it just lets people know that you're not from there but you're operating from there

[@tommiehinman1349]

Bit expensive for a kit. You must watch your own videos to record your contacts. I noticed you don't log them as you make them

[@Philip-KA4KOE]

Walt logs from the video afterwards.
