John KK4SBS writes:
Not sure what sort of … magic wizardry you’ve pulled off here but the performance on the 70cm/1.25m/2m tri-band
COMPACtenna is absolutely phenomenal!
The performance on all three bands, right out of the box, has been nothing short of incredible.
I had been running a B-10NMO (70cm/2m & 12″ tall).
Since switching to the COMPACtenna,
I’m now receiving reports of full quiet on repeaters that I previously struggled to even Rx at ~S5.
I’m now able to Rx those same machines at S8-S9+ with no issues and to my shock,
I’ve also had no trouble on Rx/Tx in the areas I used to struggle.
So thank you for engineering such an awesome product. …

5-8-9 Reports on 20 Meters!
HamR-7
Due to HOA restrictions, I was forced to find an alternative to dipoles and beams…
The COMPACtenna HAMR-7 is only 46” tall and requires only a small ground plane
counterpoise (36” x 36”).
This fit within my [very limited space] parameters.
The build quality (materials) of this unit are superb….
After resolving some SWR anomalies (due to defective magnetic mount),
the HamR-7 snapped right into spec on 40, 20, and 10 meters.
I am happy.
The COMPACtenna had me talking to NJ, PA, and LA with 5-8-9 reports.
If you have an HOA or apartment preventing you from enjoying your Ham Hobby,
consider the COMPACtenna series of antennas.

AK6OM Reviews HamR-7Digi
Results speak for themselves. I tried the WSPR digital mode, and just 5 W transmit power from Los Angeles with my KX3 and its internal ATU (similar results were obtained with the 991A). My signal on 20m and 40m was heard as far away as Canada, the Canary Islands, Antarctica, and Melbourne.
I’m happy with the HamR-Digi & recommend it to anyone with a good internal or external ATU, & a need for small footprint.
 
[20″ and HamR-7 series COMPACtenna models are designed for desired indoor placements. 
They may also be used outdoors mounted securely on a metal sheet/table/surface,
and even on a stationary vehicle as in campgrounds, POTA.
They are not recommended for vehicles in motion.]

Model  SCAN-III

Compact High Performance Scanner Radio Antenna  (<100 – 1500 MHz)
Optimized for 3 Wide Frequency Bands:
  • VHF  136 – 174 MHz
  • UHF  378 – 512 MHz
  • 750 – 960 MHz
 Digital & Analog – Superior for Public Service-Safety/Govt Frequency Bands
      Police, Fire, Sheriff, Emergency Medical, State Highway Patrol,
      Homeland Security, U.S. Federal, Military
Also superb for Transmit/Receive on MURS (151-155 MHz) and GMRS (462-467 MHz)
      as well as Ham Radio 2 Meter (VHF) & 440 MHz (UHF) Bands
      [(V)SWR: nominal <2:1  136-174MHz; 378-512MHz; 750-960MHz]
      Antenna is constructed in a fashion allowing 100 W at VHF, 75 W at higher frequencies
         Best transmit SWR results are seen with antenna mounted
         at one of the corners of the vehicle roof/hood/lid/fender.
         Performance/pattern is substantially omni-directional when mounted at a corner.
         [As a receiving antenna, model SCAN-III performs excellently at non-corners
         such as roof center, as well as at corners.]
 
ColoradoFans – CB/Ham/2-way radio…GMRS
I’ve started working on the radio setup for GMRS/Ham operations.
Put in a Compactenna based on local feedback here from HRO in town and lots of the local offroaders.
So far the reception and transmission is good…
I’m just running a cheap HT to test reception with the new setup until I can figure out what I want to do
for a real radio in the cab.
I will say with the Compactenna I can hit GMRS repeaters 10 miles away pretty easily with a 5W HT.

It works great for me on (HAM Radio) 70cm/2M and GMRS. I have good signal reads with full quieting every time I ask. Also the size is good.
Local HRO … says the 4×4 community buys them because they don’t hang up. I like it because it fits in my garage.
I’m letting my own experience with it guide me. It’s been good so far.

Scott Roberts, KB3CBC submitted 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.

azbearhuntr: …for its size this thing is incredible.
  I went 114 miles single hop today on aprs with this little guy.
  Voice comms are great as well, hitting repeaters 40-50 miles away clearly isn’t difficult.

6 Minute Video of Tom Medlin of W5KUB.com Interviewing
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 on Groups.io 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.

Report on COMPACtenna 7” model 2M/440
Dodge Durango
2 meter & 70 cm Bands tested
Analog & Digital
Yaesu – System Fusion – C4FM 4-level FSK
I had been using a ‘tall’ 2 meter/440 Ham Radio antenna on the center of the roof of my Dodge Durango.
But I moved and the new garage has a low clearance that will not allow standard antennas/technology.
It works great around town in Fargo, North Dakota.
I put the antenna on the rear left side of my car as recommended.
I’ve used it on the 2 meter and 70 cm bands
and have done both analog and digital System Fusion transmissions.
So far…two thumbs up.
And I have a four-inch clearance getting into my garage!
[So a ¼ wave 2 meter antenna wouldn’t even fit.]
BTW it was -21 degrees this morning in Fargo. and the antenna worked great!
As a follow up, I completed my 300 mile trip last week
from Fargo, North Dakota to Rochester, Minnesota.
I knew roughly how far the repeaters reached as I traveled along I-94 with my old tall antenna.
I am happy to report that my new 7” COMPACtenna had the same reach to those repeaters
as my old tall antenna.
I was picking up and reaching the repeater as far as 30 and more miles away,
which in hilly Minnesota country is not bad at all.
So, overall, I give the antenna a “two thumbs up”.
I think I made a really good buy.

KARMA   meets   COMPACtenna
(Karma: Fisker luxury hybrid.)
I installed a COMPACtenna model 2M/440 and it works amazingly well. 😉
My tests so far are with a handy with only 4 watts …
I could open a DMR repeater with 0 percent packet loss,
always signal 8/9 for about 20km distance whilst driving,
before entering an urban area and even there I got less packet loss in transmit then before.
The antenna I used before on this vehicle was a window mounted Diamond antenna.
In my opinion this antenna is also aesthetically less intrusive.
And it looks cool !

COMPACtenna The Spectrum Monitor May 2019 FRONT PAGE    By Chris Parris    ” … The COMPACtenna … seemed too good to be true.
The antenna appears to be very well built and not flimsy.
The COMPACtenna SW does indeed work as advertised.
It appears to be useful in situations where a larger or longer antenna is not practical or possible.
I did receive shortwave stations better than the standard whip antenna provided on basic shortwave radios.”
 
On 10,12,15,17m the COMPACtenna model SW receives better than a 5m active loop
and 1.2m mag loop.
The SNR ratio of your antenna is amazing on the 20m band, the reception of FT8 is better than my whip and magnetic loops including a 1.2m mag loop and even a 5m active loop.

Short length and short height (reduced torque) with quite low weight and wind load
  allowing use of inexpensive TV antenna style rotors
Very little assembly required
