- Dr. Nilsson will present his patented COMPACtenna invention of small High-Performance antennas that helps allow passage into garages and provide a stealth solution for Homes & HOA's. His designs reduce losses of standard matching circuits with a resonating signal-producing matching system intrinsic to the antenna geometry, produce strong magnetic and electric near fields, and create diverse EM far fields thereby reducing flutter and increasing Reliable Range.

COMPACtenna - Patented Small High-Performance Antennas - VHF/UHF & HF
Dr. Jack Nilsson is an inventor of revolutionary Antenna Science & Technology. With his early formal education focused on mathematics and physics, he was awarded the Silver Medal by the Mathematics Association of America. He then earned his undergraduate and M.D. degrees from the University of Akron, with honors. His physician internship and residency in Family Practice were at Cleveland Clinic - Fairview General Hospital.
After over a decade as a Family Physician, his work on revolutionary antenna science & technology found him moving to Chief wireless engineer as well as senior antenna design engineer positions and working with private enterprise/investment entities in building antenna companies based on his unique ground-breaking antenna patents.
As part of that work, Dr. Nilsson received a Formal Technology Honor from the U.S. Secret Service. His various patented designs are used by many entities including such as Washington DC Homeland Security, the Cleveland Clinic Mobile Stroke Ambulance, diverse WiFi and Cell Phone networks, US Secret Service, Public Service agencies, and Ham Radio Operators.
Dr. Nilsson’s COMPACtenna Invention:
Reduce losses of standard matching circuits
Antenna geometry - resonating signal-producing matching system built-in Improve bandwidth of short antenna with spiral metal sheets
‘Magnetic Field Resonator’ - reduced near field noise Diverse EM Fields reduce flutter
Improved:
Non-Line-of-Sight multi-path communications (Real world environment we live in)
Temperature and humidity inversion pathways, tropospheric propagation
Satellite communications (hemispheric pattern, elliptical polarization)
Stabilized signal with diverse HF pathways
Does it work? See Ham Radio Crash Course's testing at ua-cam.com/video/AcS-XBjDrTM/v-deo.html The results are at 9:14 in his video.
When this guy talks, I'm lost but I love the enthusiasm. I have the Scan III on the corner of my vehicle and it's the best antenna I have ever used for mobile. I'm on GMRS more than ham and it's great.
The VHF/UHF and the ScanIII models work very well when your mount location has very poor or no ground plane. For that purpose it is fantastic when compared to other antennas. Still, the other various mobile antennas tested worked better with a ground plane. Basically, a Compactenna is a tool to have. I’m happy with mine.
I want to see a radiation RF pattern, particularly what it would be upon being mounted on the roof of an average-height pick-up truck. Or, maybe, mounted about (approx.) 20 feet off the ground. Then, maybe, I might buy one from Ham Radio Outlet to use on my 2nd-floor apartment balcony railing. I know already that HRO would appreciate my business, as I've been a past customer.

Drop him a line... I'm sure he'll send you some.
Nice
Why was the QA section removed? What questions were asked? What were the answers?
To shorten the overall length, more desirable for viewers, likelihood of being viewed.
I hope you get much enjoyment and enrichment from this novel technology, Ryan.
For Q&A session you may see: COMPACtenna Quanta - Near & Far Fields - 1 Hr. Talk, then 20 minute Q&A - Conejo Valley (CA) Amateur Radio Club 1.20.22 - UA-cam .
Kurt N. Sterba could make a novel out of this guy.
...And yet those who actually use his Compactenna say they do exactly what he says they do.
Blasts right past the math or any justifiable explanation as to how this mystery aluminum foil antenna actually works.
And yet... according to those who actually have one and use it, they work - just as described!
@@HamRadioOutlet I have one and have used it. Read my comment again...he blasts right past any actual explanation as to how it works. An assumption here is either he thinks the average ham is too stupid to understand, he's using some smoke and mirrors, or both. They are too expensive to cut open for science, but someone should.
@@SIGINT007 I read your comment again. My response stands. Many have cut them open, there are photos available on the internet, so there's no mystery as to what's inside them.
@@HamRadioOutlet "Images", really? I couldn't seem to find any 'images" on Google of the particular antenna; 20m/2m/440 of it being cut open or disassembled! And no reasonable person appreciates their intellect being insulted.
@@charleswoods2996 Took about a minute of searching to find the patent, complete with diagrams. There are images on the QRZ forums of COMPACTennas cut open. It's a bit late to mention a 20m/2m/440 "particular antenna" when his discussion talks about all of his antennas, and you only mentioned this "particular" antenna 3 comments into the thread.
Do you mean antennae?
No. "Antennas" is correct. See grammarist.com/usage/antennae-antennas/ 🙂
