- In todays video I do some R&D on a new Fan Dipole antenna, Tuning, getting the wires seperated and try to make a few contacts to test it out.

Great work Chuck 👍
Nice project. The spacers are a problem with deployment for sure. I don’t use any, and I guy off each of my di-poles individually and don’t have to worry about twisting and it is very easy to set up too. I cut and tuned wires for 40M, 20M and 10M. Stringing up 40 M on a 18 foot pole, and tying off the ends with cordage at about 8 feet above the ground on each end. Then do the same for 20 M letting it hang below 40, repeat for 10 letting it hang below 20. I also have 40 M 25 degrees offset from the 20 and 10 M dipoles, it is just NOT critical that they be in the same horizontal plane. Using my FT 710 I work all the advanced portions of 40, 20, and 1.5mhz of 10 without the internal tuner. Bonus bands, 15 M with the internal tuner, and hold on, 6M with the internal tuner from 50.1 to 53.1 mhz, yeah this antenna rocks. Take your time tuning each dipole starting at 40 m working to 10 m, and you will be rewarded. I tuned with only a vswr meter. 73 and good DX. N9XDS.
A fan dipole is absolutely one of the best antennas out there. No tuner required and when fed with the right coax can handle high power.
Nicely built, Chuck. 💯👍🙋♂
Chuck in Mad Scientist Mode is best Chuck!
Lionel they let me loose sometimes lol.
Thanks for the video Chuck. Looks like when it’s available I will have another antenna to build. I have the others and love them. Looking forward to this one!
Looks and sounds good!
Looks like something for the wish list! I was going to make a fan dipole when I first started in 2020 but I got a dipole from an Elmer. I came here from CaHR
The Smokin Ape is everywhere!
Yes he is!!
Hard to beat a fan. I really need one for 30,17 and 6m
Jay you caould build it for those bands and it actually tuned up on 6m the way it was.
I can hang a fan dipole like that but the legs would be at a 90 to each other instead of being in the same plane. The pole is at a fence corner and I have a 100 feet in each direction. Would that right angle affect the radiation pattern adversely. I can't find any literature on this. Hope you know. 73 KN6ZVI
how do you make the coax attachment? I did see the so239 fitting adapter but how to the wires attach? thanks!
I want a fan dipole for home but want it to do 40-10m.
Any progress on this Chuck?
I already have your end fed that I still need to build... when I get a HF radio, maybe at Dayton or shortly after. :)
Don you could build our Mercury into a fan dipole for 40 and 10
Chuck, I'm doing a monoband dipole antenna for 15m same way with parts from Mercury antenna . Where did you get info on the balun at the top? is it just coax wrapped around a toroid? any detail would be great. thx! oh nevermind, this would be the same 1:1 transformer as with the Mercury instructions right?
Yes, You can use coax also
Chuck, what was the orientation? Which way was your fan pointed?
I was setup north to south, seemed thay propogatio was north south and short that day.
