- Dr. Jack Nilsson, N8NDL, spoke to W6SD, the San Fernando Valley (CA) Amateur Radio Club, on Jan. 21, 2022. He is the inventor of the COMPACtenna, which as the name suggests are small in size yet deliver the performance of much larger antennas.
The UHF COMPACtenna, for the 70cm, 1.25m and 2m bands, comes in 7.5-inch and 9-inch versions for mounting on vehicles. A model designed for stationary use, which covers UHF and the 20m band, is just 20 inches tall.
Dr. Nilsson has 30 years of antenna and electromagnetic engineering experience.
He earned his undergraduate and M.D. degrees from the University of Akron, with honors. He was awarded the Silver Medal by the Mathematics Association of America, and received a Formal Technology Honor from the U.S. Secret Service.
I have to say I watched for an hour but unfortunately learned essentially nothing.Testimonials don't work for me. I want to see antenna analysis, modeling, A-B range comparisons.
But that was just a presentation to a ham club, so I looked through the website and unfortunately saw nothing concrete there, either. So I think I'll just not be concerned with quantum entanglement and my antennas. I'll just continue to design and build my own that are suitable for each application, and save $100. It's fun, I learn a lot, and that's what ham radio is really all about.
Design, and build something VERY, VERY similar, except only a higher power capacity!
I've been trying to trust any and all information anyone can find on this antenna. When I hear the term "quantum" anymore it makes me think of all these videos on RUclips that are basically immersed in "magical thinking". 🤣🤣🤣

I cannot find the microbeam antenna anywhere for sale can you help me out
Hi Question for this antenna for Jack. Does this antenna have to be used with a mag mount? I want to install it on my aluminum roof rack (Prinsu) with a simple L bracket at the front corner of the rack. Would it have the same performance as a mag mount in the same location?
Hi Jordan. A variety of mount types may be used. (NMO ... Magnet, L-Bracket, through-hole, etc.) Please see the INSTALLS page of my COMPACtenna website. At an upper corner of the vehicle and in this case the L-Bracket at a corner with screws into the metallic rack is generally the better location for SWR, check it. With good SWR the performance is generally substantially similar on a vehicle with (at least capacitive) coupling of the metal roof rack to the metal of the vehicle.
