7.5″ model 2M/220/440
Not sure what sort of … magic wizardry you’ve pulled off here but the performance of 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 am now receiving reports of full quieting 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 with no trouble on Rx/Tx in the areas I used to struggle.
So thank you for engineering such an awesome product. …

COMPACtenna REVIEW 2M-440 LONG RANGE Enthusiast N3JHU
[COMPACtenna is LESS restrictive than most antennas which have only one optimum spot, being the center of the roof ONLY.
All COMPACtenna models have MULTIPLE optimum possible locations, the upper corners of the vehicle.
Some have found, depending on their vehicle construct and mount style they use,
that they also get good results from the corners of the hood, or trunk lid, etc.]
 
ELECTRIC   VEHICLES
RF noise (EMI) that can be generated by increasingly popular electric vehicles can lead to problems (EMC) with receivers and transceivers.
The COMPACtenna with its beneficial balance of substantial electric and magnetic components in the Near Field
(and field-photon synergistic harmonious summation resulting in a powerful EM Far Field)
has the potential to mitigate such interference.
Danny Harber, KI5EXY, active in the Montgomery County, Texas area FEMA, Search & Rescue, and ARES communications found this
to be another important benefit of COMPACtenna:
COMPACtenna TESLA & COMPACtenna MEET - Danny, KI5EXY in Texas - PHOTO
On my Tesla vehicle, I have been testing various antennas including long high gain VHF/UHF ones.
There is a noise problem when driving as well as when parked in the ‘On’ mode,
even with the repeater only 8 miles from my location.
The COMPACtenna does not have that issue.

BASE STATION
I have been having great success with the COMPACtenna 2M/440+.
Combined with the COMPACtenna Counterpoise, it is the best dual-band antenna I’ve used in a base configuration.
I live in New York City where line of sight is non-existent. I am now hitting repeaters far off into other parts of the city and beyond
at 30 feet elevation with 5-10 watts of power maximum. …
SWR’s on the 2m band barely move the meter, and 70cm SWR’s are less than 1.5:1.
I’ve never been able to achieve those levels with any other dual band antenna I’ve used.
It was also the easiest antenna setup I’ve been through over the last 20 years.

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.

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.

COMPACtenna REVIEW 2M,440 on DXE

 
Non-Line-Of- Sight – Success with COMPACtenna
Simplex – Vehicle to Vehicle
I purchased one of your dual band COMPACtenna’s for my wife’s van.
She has 12 inches of clearance into our garage,
so we had to use a low profile antenna.
This evening, she and I talked on my drive home from work on 2 meter simplex.
We live in north western Michigan in a hilly region.
My wife was parked below the
level of the street that runs past our house.
As you can see in the attached Google Earth map, the hills
are over 200 feet higher in elevation than where my wife was parked.
We were both surprised on
How clear the signal came through.
In the past, we had a difficult time maintaining contact…
Thank you for making the COMPACtenna.

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.

I have been having great success with the COMPACtenna 2M/440+. Combined with the COMPACtenna Counterpoise,
it is the best dual-band antenna I’ve used in a base configuration.
I live in New York City where line of sight is non-existent.
I am now hitting repeaters far off into other parts of the city and beyond at 30 feet elevation with 5-10 watts of power maximum. …
SWR’s on the 2m band barely move the meter, and 70cm SWR’s are less than 1.5:1.
I’ve never been able to achieve those levels with any other dual band antenna I’ve used.
It was also the easiest antenna setup I’ve been through over the last 20 years.

Model  2M/440+

   All the high performance of the 7.5” model 2M/440,   PLUS an additional 1.5dB of gain, 

   and greater power handling capacity. 

   It is for those where 9″ is allowable/desirable and the operator wants that extra ‘edge’.

Heartland Radio eBay Affiliate customer comments on 9″ model 2M/440+ along with the CompacCounterpoise:
I have been having great success with the COMPACtenna 2M/440+. Combined with the COMPACtenna Counterpoise,
it is the best dual-band antenna I’ve used in a base configuration.
I live in New York City where line of sight is non-existent.
I am now hitting repeaters far off into other parts of the city and beyond at 30 feet elevation with 5-10 watts of power maximum. …
SWR’s on the 2m band barely move the meter, and 70cm SWR’s are less than 1.5:1.
I’ve never been able to achieve those levels with any other dual band antenna I’ve used.
It was also the easiest antenna setup I’ve been through over the last 20 years.
