The SMA connector is a semi-precision sub-miniature RF connector mainly used with coaxial cables. It’s small in size and has a screw connection for easy installment.
The radio equipment usually has a Male SMA connection for antennas. However, high-quality antennas often require a UHF Female connection to work correctly.
So here are the best SMA to UHF Adapter Connector kits.
5 Best SMA to UHF Connectors
Following are the best 5 SMA to UHF connectors.
- Onelinkmore Ham Radio Adapter SMA to UHF Antenna Adapter Kits
- DHT Electronics Handheld Antenna Cable SMA Male to UHF Female
- EXGOOFIT SMA-UHF RF Connector Kit
- Superbat SMA to UHF Adapter Cable and Kit
- YOTENKO RF Coaxial FPV Connector Kit (16 Items)
Following are the type of connectors you may need:
- SMA Male to UHF Male (Same as UHF Male to SMA Male)
- SMA Male to UHF Female (Same as UHF Female to SMA Male)
- SMA Female to UHF Male (Same as UHF Male to SMA Female)
- SMA Female to UHF Female (Same as UHF Female to SMA Female)
Below are details of each kit and which one you should select.
1. Onelinkmore Ham Radio Adapter SMA to UHF Antenna Adapter Kits
Onelinkmore is a renowned brand for radio adapters, cables, and antennas.
The SMA to UHF conversion kit by Onelinkmore is no exception in terms of its quality, durability, and pricing.
I personally like and recommend products from Onelinkmore, and I have liked this adapter kit from them.
This is the upgraded kit by Onelinkmore, which is also tested for high corrosion sea environments with high humidity and excessive salt. It comes with a special plating to resist sea salt corrosion.
These new adapter kits have a higher quality build than their predecessors.
The Package contains the following adapters:
- SO239 FEMALE to SMA MALE
- SO239 FEMALE to SMA FEMALE
- PL259 MALE to SMA MALE
- PL259 MALE to SMA FEMALE
- Salt Spray Environmental Test
- Two-way radio adapter
- Passed real SWR test
- Work with Low Frequencies
These adapter conversion kits are designed for use with two-way radios. This kit works with any radios that employ an SMA-UHF antenna connector.
For me, these Onelinkmore adapter kit works great with low frequencies of less than 300 MHz.
2. DHT Electronics Handheld Antenna Cable SMA Male to UHF Female
DHT is a well-known brand in RF Radio accessories for the quality of products they produce. This SMA to UHF connector cable is no exception.
The package arrived with two SMA Male to UHF Female cables. Although this set does not cover all SMA to UHF combinations, this SMA Male to UHF Female is mainly needed.
The quality of the cables and connectors on both ends is phenomenal. It looks like it will meet the promised one grand mating lifetime making it perfect for most RF applications, Wireless LAN Devices, and external antennas.
The cable length is also just perfect. Not too long, so you need to use zip ties. And not so short of making it hard to fit various requirements together.
- 2 x SMA male to UHF female cables
- Commonly Used in RF Applications
- 6 inches RG316 Type Cable
- Pure brass with excellent connectivity
Although this version is SMA Male to UHF Female, here is a link to SMA Female to UHF Female version from the same DHT Electronics Brand.
3. EXGOOFIT SMA-UHF RF Connector Kit
This Exgoofit SAM to UHF adapter kit is the third on our list. Unlike DHT Electronics, this one comes with all male-female combinations. And it has got two adapters for each possible configuration, making it a set of 8 adapters.
At the time of writing this article, the Exgoofit adapter set of 8 is cheaper than the four-piece set by Onelinkmore.
It does not mean it’s a low-quality product after you have it in your hands. I suppose the price is competitive for the sake of getting some footing on the sales at Amazon. So more like an offer.
These adapters are made with pure 99.99% copper, which is then nickel plated for even better conductivity. The overall impedance is around 50 ohms.
I found it quite good at retaining the analog signal with extremely low losses.
You will get the following items in the package.
- 2pcs SO239 female to SMA male adapter
- 2pcs SO239 female to SMA female adapter
- 2pcs pl259 male to SMA male adapter
- 2pcs pl259 male to SMA female
- Widely use for Antennas
- Impedance: 50 ohms, Low-loss
- Life-time Warranty
Exgoofit is very confident about its quality, and they offer a whopping lifetime warranty.
4. Superbat SMA to UHF Adapter Cable and Kit
This is one of the most exciting adapter kits on my list. The best thing about this kit is it comes with a coaxial cable you can buy in six different sizes.
The available sizes are 6 inches, 12 inches, 20 inches, 3 feet, 6.56 feet, and 10 feet.
Although this kit does not cover all possible SMA to UHF combinations (Can’t address SMA Male to UHF Male connection), it still takes care of the most common types.
- SMA Male to UHF Female, 6 Inches in length
- SMA Female to Sma Female adapter
- SMA Female to UHF Female
- SMA Female to UHF Male Adapter
- CABLE- Connector 1
- SMA Male; Connector 2 SO239(UHF Female)
- Cable Length: 15cm.
- Impedance: 50 Ohm
The quality of these adapter kits is fantastic. One wishes to make them a decoration piece on your dresser. The cable quality is also very excellent.
Superbat offers a one-month replacement warranty for these connector kits.
5. YOTENKO RF Coaxial FPV Connector Kit (16 Items)
This Yotenko RF adapters set is a PRO set with 16 different types of adapters catering to all types of conversion scenarios.
I have found them useful for various RF applications like antennas, broadcast radios, WiFi, etc.
The Yoyenko set comes with the following converters:
4PCS UHF to SMA adapter
- SMA female to UHF female SO239 coax adapter
- SMA male to UHF female SO239 coax adapter
- SMA female to UHF male PL259 coax adapter
- SMA male to UHF male PL259 coax adapter
4PCS BNC to SMA adapter
- BNC female to SMA female coax adapter
