K25
UHF Short Stubby Portable Antenna
Custom fine-tuned with Precision and Accuracy
for High Performance Analog or Digital communications
in the
UHF 460 to 482 MHz
frequency range
If you are looking for more performance than what any known-brand OEM or any other aftermarket mass produced portable antenna claim to achieve you are in the right place.
Each of our antennas are retuned by hand to deliver absolute maximum communications performance with real certified results over a guaranteed frequency range.
We create and develop outstanding “no BS products” that meet communication needs better than any competitor.
Fact:
a
Bigger
antenna is usually
NOT BETTER
,
just really
Big!
Our custom compact portable antennas are optimized for amazing high performance through careful frequency resonance tuning, intricate impedance matching, copper element efficiency, and a predictable omnidirectional signal pattern.
No other look-a-like antenna can compare with our high standards and measured results.
This listing is for one UHF Stubby antenna that was purchased new directly from a known-brand and then custom fine-tuned with lab grade equipment to specifically cover the
460 to 482 MHz
frequency range with a VSWR of 1.5:1 or better for true high performance FM analog or digital communications range.
The portable radios and remote speaker mics shown in the photos are shown for reference only and are not included.
Our antenna will also reduce the current draw on the portable radio battery during transmit for a longer battery run time without having to change batteries.
We include a
90 day
limited warranty against any defects in materials or workmanship.
If you require a different antenna frequency range anywhere in the
406 to 512 MHz
UHF band please see our special
C25
UHF antenna listing.
The
K25
antenna is only
2 inches
tall with a final height tolerance of plus or minus 1/8 of an inch as measured from the bottom of the weather skirt to the top cap of the antenna. The antenna covering is made of black flexible PVC and has a bottom weather skirt to protect the RF connection on the radio housing. The bottom of the
1/4-32 threaded stud antenna connector
is color coded with a single
green
stripe
as shown in our photo.
We silver solder all reworked internal antenna connections.
The retuning of the short stubby antenna achieves a minimum signal gain of up to
+3 dB
that will effectively double your transmit and receive signal power due to the very low VSWR and excellent 50 ohm impedance match as compared to an untuned antenna.
Our retuning also allows for a much smaller antenna height without any loss of performance by eliminating all of the unused space inside the antenna covering.

It will also work great on top of any Public Safety Speaker Microphone (PSM or PSSM) that requires a UHF antenna with a SMA RF connection to be used on the microphone housing.
Our antenna does not have GPS capability that some radio models require.
This antenna meets all of the following criteria;
1.
Must be a new known-brand antenna and not a cheap junk look-a-like copy from China.
2.
Be as short as physically possible for a low profile with great communications range.
3.
Must be professional looking on the portable radio or if used on a public safety service microphone.
4.
Use a 1/4-32 threaded stud connector to properly fit portables as listed above
5.
Exhibit an excellent resonance with a very low VSWR of 1.5:1 or less over the whole frequency range as stated.
6.
Must maintain all specifications over the temperature range of -10 to +120 degrees Fahrenheit.
Our custom tuned UHF antennas have greatly improved communications for all business, consumer, commercial, fire, GMRS 462-467 MHz, government, industrial, public safety, police, and rescue radio users who operate in the shared UHF 406 to 512 MHz
radio band.
It is a known fact that the most important part of any radio communications is the antenna system.
The antenna is the device on a radio that converts RF power into radio waves during transmit and radio waves into RF power on receive.
All transmitted and received signals must pass through the antenna system for any radio to work.
A respected radio engineer once said, “If you had 100 dollars, invest 99 dollars in the antenna system and 1 dollar in the radio and you will always have great communications”.
After many years of our own experience we have found that this statement to be true especially for today’s FM narrowband radio communications.
We have witnessed portable radios worth thousands of dollars using cheap unknown quality OEM antennas get beat out performance wise by users with radios one forth the cost using our fine-tuned antennas.
VSWR is the efficiency measurement ratio of RF power that is being converted into radio waves by the antenna system as compared to the RF power that is not converted and reflected back into the radio as wasted energy. A VSWR of 1.5:1 has been and still is the customary maximum upper limit used in professional land mobile radio communications to determine a good transfer of RF power. Any VSWR above 1.6:1 is poor and any VSWR above 2:1 is definitely bad for performance and the health of the radio RF power output amplifier.
Sadly many companies that manufacture products in China now use a VSWR of 2:1 as their good reference point to market their poor quality products and make them appear to be way better than what they actually are.
We do not recommend using a standard remote speaker mic (RSM) with our custom tuned stubby antenna since the speaker mic coiled cord will physically block most of the stubby antenna performance. Portable radio antennas need clear space in all horizontal directions to work best.
If you absolutely must use a RSM with your radio the best choice would be to use our custom tuned high performance whip antenna that is tuned to work with a RSM coiled cord obstruction.
The second best choice would be to tie wrap the coiled cord to go in an immediate downward direction close to where it exits the radio accessory connector to avoid blocking the stubby antenna signal.
Please see our other antenna listings for our high performance whip antennas.
We have built thousands of custom tuned antennas for our customers with excellent results and zero defects.
Our company has over 30 years of experience in creating high performance and cost effective antenna solutions.
Why continue to operate with an unknown portable radio antenna
when you can STEP UP to the TRUE level of
portable antenna performance!
