Description:
This antenna kit is the standard solution for projects where the microcontroller is housed inside a metal or thick plastic enclosure, which typically blocks internal signals. By using the included IPEX (U.FL) to RP-SMA pigtail cable, you can mount the antenna outside the chassis.
The antenna features a swivel design, allowing it to be rotated 90 degrees to optimize signal polarization. With a 3dBi gain, it provides a more focused and powerful radiation pattern compared to the small "trace antennas" printed directly on PCB modules.
Features:
Significant Range Extension: Boosts signal strength and reduces packet loss in IoT applications.
Flexible Mounting: The pigtail cable allows for easy chassis mounting (requires a 6.5mm).
Wide Compatibility: Works with any 2.4GHz device using an IPEX/U.FL connector, including ESP8266, ESP32, CC3000, and many WiFi routers.
Adjustable Angle: The hinged design allows for vertical or horizontal orientation to match your router's signal orientation.
Low Signal Loss: High-quality RG178 coaxial cable ensures minimal signal degradation between the module and the antenna.
Specifications:
Frequency Range: 2.4GHz−2.5GHz
Gain: 3dBi
V.S.W.R.: ≤1.5
Impedance: 50Ω
Polarization: Vertical
Antenna Connector: RP-SMA Male
Pigtail Cable Connector: IPEX (U.FL) to RP-SMA Female (Pin)
Cable Type: RG178
Operating Temp: −40°C to +85°C

Durable and Great for Teething!
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
This Nylabone Power Chew Textured Ring is a great find! It’s a pretty big ring, which is perfect because my puppy can grow into it. She already loves it and spends a good amount of time chewing on it.
She’s a big teether, so I was specifically looking for something she could gnaw on that wasn’t plastic, and this has been so much better than the other things she tries to get her teeth into.
It seems durable, keeps her occupied, and the price is great for the quality. I’ll definitely be buying another one when needed!

Great toy for my beautiful Canela, she found it fun to play and chew all day long, the material is very strong, she could not destroy it, I did not smell beef or meat.

As durable as expected.
Size: Large, Color: Femur Bone, Size: Large, Color: Femur Bone
My dog loves it—more than any other bone she’s ever had. It’s not quite as durable as regular nylabone, but we expected that. This photo was taken after around 2 hours of super aggressive chewing by a very big German shepherd. It has no discernible smell, but obviously it has a flavor because she doesn’t want to put it down even for trips outside. It’s soft enough that it doesn’t cause that “are their teeth breaking?!” sound that a lot of offbrand nylon chews have. The classic femur shape is perfect. It’s the easiest shape for her to hold naturally. All around, perfect dog chew.

Heavy duty chewing, not heavy duty dropping
Size: X-Large, Color: Textured Ring
My super chewer loved this toy, great shape, provided long lasting entertainment. However, when he dropped it from his mouth onto our epoxy flooring (not a far drop as he’s only 50lbs) one chunk broke clean off at the 2 smaller joints. Although we kept the larger piece for a while, a similar drop a week later broke it again. Considering this is fairly inexpensive, I wasn’t expecting it to be indestructible. It’s just strange how it broke. Will probably buy again to test one more time.

My dog loves these things
Size: Large, Color: Femur Bone
My dog loves these things. They don't smell at all. It was a great price. It's big enough for my Frenchie. It's pretty durable but he is able to gnaw it rough so I do have to replace them periodically.
