I'd imagine you'd reach the point eventually where the resistance would be detrimental.
and yes, a better bandwith antenna wouls simplify tuning and improve audio response. Would pair great with AM Stereo!
Carl, you might need to get a few barrels for KDX Barrel Round Radio. Play Rodeo music on it.
That is exactly the reason why i have been working on bandwidth improvement, as i want to transmit c-quam !
The capacitance hat really helps in both ways, i am working on a larger top hat and have been gathering interesting data for design and performance.

Barrel Round Radio and rodeo music is the thing, Mighty 1650!
Also, in Holland they have Barrel Organs that roll down the street on wheels being played by an operator who turns a crank and I guess the notes are on a mechanical drum. Big fat sound.
Maybe Rob Veld has a Barrel Organ.
Did I miss it. Whatever happend to the "upside down" antenna someone had proposed?
They were going to put their 8 foot copper rod 6 feet in the ground and use that for the antenna. Can't remember what they proposed for the ground side of the antenna system.
My antenna book says that the counterpoise ground part of an above-ground antenna results in a mirror image of that above ground antenna so that it's like having two antennas... one is right-side-up and the other one is upside-down.
So I got to wondering.... What if you, I, or him, placed a large mirror showing an image of your antenna. Mirrors work by reflecting light frequencies and make a duplicate of whatever is seen in the mirror, and radio frequencies are like light frequencies, so I'll bet a mirror would double your antenna's output. It wouldn't work at night unless it did.
Well actually mirrors use a metalized reflective surface. If you could connect your ground lead to it...
I used one to make a large capacitor, placing tin foil on the outside.
MRAM your mirror capacitor is either a very funny joke or a very seriously brilliant idea.
Carl Said: "I also heard somewhere that a wider diameter antenna increases the bandwidth, and I think that directly determines the audio frequency response that goes out. Is that still true?"
I said: Yes.

Now you're talking! I have a Chris Cuff C-Quam AM Stereo transmitter that was built by Chris Cuff himself that I have plans of putting into operation.
The long awaited hold up is planing an antenna design that will work well.
I am not limited with putting an antenna on the property, I rent, but I am allowed to put outdoor antennas on the house chiminey. Building a ground based antenna is possible to, however, I have to explore what I can can do legally with limited ground space.
Placing ground radials might be a challenge because a lot of the yard has ledge rock just below the dirt surface, some of which is exposed above ground surface.
A lawnmore would surely grab those wires and all hell will break loose. I do have a wooded section right behind my house, but in order to have those radials equal in length, I would have to place the driven radiator close to that wooded area and expand the radials into the woods and into the yard. Who knows what a challenge it will be trying to place 20 or so radials on a circle.
I also have to try not to step on any gray areas with any plans I come up with. I do not have any proper equipment for testing field strength, and my biggest stall is devising something that works beyond expectations, but does not fail an inspection if one was conducted.
I have also thought about removing the kit from the plastic case Chris Cuff placed it in and place it in a decent metal encloser. Of course, if I choose to place the transmitter outdoors at the antenna base, I have to purchase a water tight encloser instead.
My plans are to go AM stereo when I do return to the airwaves. I have a Realistic TM-152 AM stereo receiver, so I am capable of hearing the signal in AM C-Quam stereo.
Bruce.
As long as your antenna is not more than 9.5 feet to 10 feet high your cool. Now if you have a 5 foot ground wire than your antenna can only be 5 foot high. So 4 foot ground wires would make your antenna about 6 feet high as far as the actual antenna as far as I understand it. Nothing says you can't have a high gain antenna however. You may get a mile or 2 on your AM Transmitter.
i'm currently building a hanging dipole out of 5 gallon buckets end to end and wrapping it in some form of sheet metal and using a broken cymbal from my drums as a rain sheild up top. transmitter is gonna be solar powered and audio is fed via 2.4ghz A/v transmitter/rec. all on board the 9' 8" stack. gonna abandon ground and go for height
RADIODIRTYSPRINGS1700 your dangling 5-gallon can dipole will wake the neighborhood when it blows around in the wind.
If it flies apart there'll be giant cans rolling everywhere.
im bolting the whole thing together in one piece. it won't fly apart. i will be polak-rigging it well and tying it off to the sway will be limited
No Carl, I don't have a barrel organ. But I have this record:
Rob Veld
Rob that is really super good. I love that sound and it actually sounds a bit like barrel organ music that I've heard.
That's perfect feel good music for all day.
