That might be a click-bait subject line, but the article in the link below describes an antenna currently being developed by researchers at SLAC National Accelerator Laboratory for the VLF band that fits on a small camp table. Given that they claim the antenna can be scaled to other frequencies, it could be that we could see viable amateur radio antennas the size of a bird house on a pole in an HOA restricted neighborhood. And, as we are not likely to see a time where the HOA ceases to exist, this could be the future Ham's antenna. https://www.electronicdesign.com/an...9aa5f61348b723e20f&oly_enc_id=1017B6675490H5V
Did anyone ask how mechanical vibration equated to non-ionizing radiation? I though I was reading the Onion for a second. "These antennas can resonate in a very small footprint while exhibiting low losses. To achieve this, they created an ultra-low-loss, piezoelectric electric dipole driven at acoustic resonance."
Sigh. Sigh. 1. It's not about the antenna. 2. RF "is" non-ionizing, regardless of what antenna is used. 3. The piezo material resonates at acoustic "frequencies" which happen to be the same as the desired RF frequencies (VLF at RF, VHF at acoustic). Scaled at VLF frequencies, at minuscule power. Microwatts. Read the article carefully. Misinterpreted articles seem to be impossible to kill. sigh.
"... amateur radio antennas the size of a bird house on a pole in an HOA restricted neighborhood." ... and they still would violate the NO antenna HOA rules
Next time I'll be sure to do a search of the topic to ensure I don't submit an identical topic. My apologies.
