I asked this at ChatGPD...Can I substitute a different antenna on a Procaster AM certified transmitter?
Answer: copied from page text...
"Yes, you can substitute a different antenna on a certified Procaster AM Part 15 transmitter, but there are a few considerations to keep in mind:
1. **Compliance**: Ensure that the new antenna maintains compliance with Part 15 regulations. The total length and design of the antenna should not exceed the allowed parameters for unlicensed AM broadcasting.
2. **Impedance Matching**: The new antenna should ideally match the impedance (usually 50 ohms) of the transmitter for optimal performance. Mismatched impedance can lead to reduced efficiency and potential damage to the transmitter.
3. **Performance**: Different antennas may offer varying performance characteristics. Make sure the antenna you choose is suitable for AM broadcasting and designed for the frequencies you intend to use.
4. **Installation**: Pay attention to the installation height and placement, as these factors can affect your signal coverage and interference with other signals.
Always check the manufacturer's guidelines and consult with a knowledgeable professional if you're unsure about the substitution". end quote.
And I did consult with the manufacturer, an electronics engineer, and was told a wire is no different that the aluminum rod. Electrically/physically the same thing.
A detailed answer with some room for argument but overall correct.
I think I have a new best friend named 'meta_ai'. I just asked it a question very few people in the world have an answer for (are there other works similar to Sibelius 7th Symphony?), and in LESS THAN A SECOND it spit back a lengthy list of composers and compositions that bore some resemblance with Sibelius 7th.
Because I am so smart I am aware of all the works and composers named and don't happen to consider them on a plane with Sibelius, yet what META suggested was more than even most music professors would know anything about.
Yes, the AI Thing was well informed about Part 15 range!
So I got familiar with it and said:
"I think I love you. Can I play with your ears?"
The AI Thing let me down gently by its response.

@ Rich-Powers What woman would say no if she heard that song?
She probably wouldn't say anything other than "huh??"
On my way out the door, so won't type anything other than a very brief answer. The AI chat thingy that you used was correct in asserting that the antenna should be a good impedance match to the transmitter. The "usually 50 ohms" phrase is, I suppose, sort of correct generally, but not in this case. The very short antennas we use in Part 15 AM present a very high impedance to the transmitter, so need appropriate matching. 102" or thereabouts is a tiny fraction of a full wavelength of any frequency on the AM BC band.
