Sloped Dipole Experiment

[bluejay148]

you could do the same with cb radio using slope inverted v and flat side

[AllAmericanFiveRadio]

@bluejay148

You could, 27.185MHz wavelength equals 36.181 Feet.

You explained this configuration better in 7 minutes than if I'd spent an hour reading about this kind of antenna.

[AllAmericanFiveRadio]

Thanks.

Rick... Nice vid. Normally when going from a balanced load (dipole) to an un-balanced feedline (coax) you wouuld use a balun. In the case of the dipole the pattern is nearly the same with or without a balun so most people don't bother.

Thanks Ron,

I have not talked to Dave yet. I thought he was all set up on YouTube, but almost, I'll get him going soon. Dave has been in commercial broadcasting forever. He also owned two radio stations. He was two Ham Shacks and he is able to switch out all antennas between the two. I know he has used a balun on a multiband dipole experiment. I did ask him earlier if he was going to change anything with this setup and he said NO!!!!

Rick:

Thanks for video. Would there have been any advantage in using a common mode choke type balun at the feed point other than the reflected power into the shack.

I would not think there would be a big advantage for this circumstance. Dave made sure the system is properly tuned to 40 meters, not going for anything else. This is Dave's setup and he has five slopers and none with a balun. The best thing to do here is to ask Dave that question. His YouTube Channel is "K4WDG". Also the shack is the emergence Ham Shack, the one he uses is in the house.

back in the good old days, they used metal bed springs and gutter for antennas (but you needed a match box).

[Druidemporor]

cool!! i have a 20 meter dipole and a 40 m dipole ----intresting expirament

It was a very successful, interesting and inexpensive experiment. Those three things don't happen too often. Thanks.

[rlewis1946]

Can you tell us what software Dave uses in this video?

Very informative, thanks!

Thanks.

Dave is using DeLorme Street Atlas.

[ka7cev]

Very educational video. Excellent. Thanks.

[AllAmericanFiveRadio]

Thanks. This one was fun to put togther.

Hi Rick. Great video, I have been working

on some wire antennas myself but mine have been loops. Do you know what program he is using for the maping? Keep The great vids coming I learn something new with every one. Thanks Charlie...

[AllAmericanFiveRadio]

Thanks, I'll get back to you on the mapping application.

Dave is using DeLorme Street Atlas.

Awesome setup Dave!

What would you say the "Take Off" Radiation is for your sloper!

Have you worked FT5GA & K4M yet?

Also, which method of phasing do you use on the five dipoles.

73 es gud DX!

Dave has a new YouTube User and it is "K4WDG". Try sending him a YouTube email.

[K4WDG]

I did not us and programs for these. Just cut and try. I would hazard a guess of 45deg. I did not try any phasing. I put up 5 different ones any switch between tham for the best signal. I am a broacast engineer (mostly AM dir and to try to figure this out on a sloper would be quite a challange. Yes I worked W4M on 40, 20, and 17M

Rick,

Great vid. Terrific info. I've recently been thinking about stringing a dipole antenna, but not about sloping it. My mind is now made up.

I appreciate this video. Very timely.

Regards,

John

[AllAmericanFiveRadio]

Thanks John,

You might consider contacting K4WDG (Dave) he would be happy to give you any details you may need. I have known Dave for over ten years and he has been throwing up wire all that time. This is the second time I have seen him so enthusiastic about an antenna, the first was his Ham RadioTower.

Regards,

Rick

I like wire antenners. I have to get up there and redo my dipole. I'm thinking more along the lines of monobanders with a remote antenna switching, using a stepping relay box strapped to the balun. I don't like traps. I also prefer the inverted VEE to the sloper. And the delta loop may find its way up there too. All in the someday plans. But I also plan to make a "slinky" attic antenner vid for YT. I might get rid of the Hustler 5BTV too. Someday...

[AllAmericanFiveRadio]

Depending on the surrounding environment, this has a large influence if not dictates what antenna will work for that situation. Otherwise there would only be one antenna design. Dave has built inverted VEEs and very large yagi antennas and much more. He tells me that the performance of this sloper rivals the performance of a $25K tower setup. So it all boils down to using what works best for your environment.
