A note of appreciation:

Thank you fellow Ham Radio operators for all your sincere support.

It is often a challenge for inventors to bring forth new ways of thinking/design.

Your word-of-mouth, comments on forums, and reviews help to

spread the word about this unique antenna Science & Technology.

Gratitude is also given to those who have made entries

on this website COMPACtenna ‘PRODUCTS & REVIEWS’ page

including by ARRL member Scott Roberts – KB3CBC

 who took the time to study and evaluate his COMPACtenna,

and submitted a very well written report New Year’s Day 2020.

Such detailed reviews assist in substantiating

this unique antenna Science & Technology.

Happy New Year to ALL!

                              Dr. Jack Nilsson is an inventor of revolutionary Antenna Science & Technology.

                              His various patented designs are used by many entities including such as the US Secret Service, 

                              Washington DC Homeland Security, the Cleveland Clinic Mobile Stroke Ambulance, 

                              diverse WiFi and Cell Phone networks, Public Service agencies, 

                              and Ham Radio Operators.

                              Dr. Nilsson’s 2-part presentation covers his COMPACtenna patented small yet powerful antennas, 

                              and then includes an enriching and entertaining talk about 

                              Physics of The Universe.

Excerpt from a New Year’s Day 2020 entry on this website

COMPACtenna ‘PRODUCTS & REVIEWS’ page 

[Also posted on eHam.net Reviews of COMPACtenna model 2M/220/440 ]

by ARRL member Scott Roberts – KB3CBC who took the time to study and evaluate his COMPACtenna,

and submit a very well written report:

For one specific case: there is a venerable major manufacturer whose antennas are used by first responders and amateur radio operators (me) for decades. The particular antenna by this manufacturer is used on 2/70 and gave me a benchmark to compare the CompacTenna side by side. In urban, NLOS environments, the CompacTenna beat the 2/70 antenna in every case.

With regards to the magnetic vs electric fields: a fast but inaccurate translation would be to say that this antenna functions as an omnidirectional circularly polarized antenna, and if you didn’t know any better, that’s what you would hear on the radio and see from your reception and transmission reports. It’s a lot more complicated than that and would recommend you review the various YouTube videos Dr. Jack put together to address this topic. Antenna analyzers and plots only give you part of the story, primarily based upon the E-field. It doesn’t show you, directly, what’s happening from the H-field side. Use a spectrum analyzer to compare received signals, though, and you’ll see the difference. The noise floor was reduced by approximately 3db and the signals were more evenly distributed. Signals that were close to the noise floor were observed to have increased by 3-6db, and stronger signals were slightly attenuated. The result is that there was minimal fading and the capability to hear signals that I could not using other manufacturer’s antennas.

Dr. Jack Nilsson Regarding 7″ COMPACtenna Model 2M/220/440 :

Testimonial:

Our company “Ham and HiFi” purchased a Compactenna 2M/220/440 antenna from HRO recently!
We use the antenna for testing radios we acquire from ” ham radio collections” we purchase from all over the US !
The construction of our shop / warehouse is with foil backed insulation, steel doors and steel roof
which have made using inside antennas a problem …..
But when using the Compactenna I’m now able to connect to repeaters through out the Reno / Sparks area!
Easy to install, easy to use ( no tuning ), wide banded and will handle 85 watts on 2, 50 watts on 220 / 440 !
Best of all a small footprint and it works !              I ordered another for my truck !

Summary of comments by Brad Smith, KC9UQR:

Brad Smith, KC9UQR
I use the COMPACtenna model 2M/440.
It is elliptically polarized and a very good satellite antenna.
It does work better than a vertical.
I have tried many antennas, including 1/4, 1/2, and 5/8 wave verticals and an eggbeater.
Dr. Nilsson explained the elliptical polarization.
I am very impressed by this little antenna.
The website is COMPACtenna.com .
There is a lot of info there, including videos by Dr. Nilsson that are informing.
The COMPACtenna is also very good at high elevations/working directly overhead. …there is no “doughnut hole”.
The proof is when you get out into the field and make a contact and I am doing that every day.

    By Bob Grove, W8JHD    “The prediction of signal flutter reduction was true as well;

when annoying flutter interrupted reception of weak signals on the whip,

reception was much smoother with the COMPACtenna.”
