Review: Overall good antenna if you're looking for a pole mounted Yagi solution. - Item arrived well packaged. Hooked it up with N-Male to RP-SMA Male adapter cable and then to my WiFi card and it's been working great. Currently being used to extend access to a remote connection. Pretty good signal strength so far with the only main downside being it's only 2.4GHz, which is understandable with it being meant for distance. Overall good purchase and good seller.
Review: Works well on security cameras! - I bought two of these to extend the range of my Reolink Argus PT's wifi range. My cameras are located a 1/4 mile away and have strong signal now. Just remember these antennas are directional. They have to be pointed towards your routers location!

## Questions & Answers

**Q: Can I use this indoors, my wifi adapter currently gets 1 bar, but I need to place this next to my desktop computer on the floor of my room?**
A: Yes, it is just an antenna, you can use it indoors. It is directional, be sure to aim it at your router.

**Q: will this work on a chromebook?**
A: Hi, this antenna can not work alone. It must connect to router, AP or wireless adapter or other 2.4ghz wireless device as sending/receiving tool.  If your use a external wireless adapter which has RP SMA FEMALE connector.on the chromebook. Then you can connect this antenna and pointing to the hotspots direction to extend range of reception.

**Q: What is a suggested compatible router/receiver for this antenna?**
A: Hi, This antenna can compatible with most of the router and receiver as well as they are using 2.4GHz frequency, just make sure the connector type can match each other. This antenna connector type is rp-sma male (with a pin inside), and most of the connector on router is sma female (without pin inside).  If your router/receiver connector is not a sma female,you will need a convertor cable to connect between them.  More over,  if you want to set the antenna far away from the router, a extension cable is a good option.You can find all these cable in our store. Thank you.

**Q: Can this be lighty painted without affecting performance?**
A: So long as there is no metallic stuff in the paint, I think you'll be OK. I have mine painted black and it works quite well.

### ⭐⭐⭐⭐⭐ Nice Yagi-Uda, with some advice
*by P***O on March 12, 2021*

I needed a Yagi-Uda antenna to connect my garage shop computer with the house WiFi. The distance from the wireless router is ~200 feet. This product arrived quickly, and all of the elements (secured to the boom by pop rivets) were firm and secure. For whatever reason, the manufacturer decided to make the feed line terminate in an RP-SMA Male connector. This can be an issue with the majority of standard extension cables, but given that I had ~30 feet to cover via coax in order to connect the wireless card, did not pose an issue. I used an adapter fitting that terminated in a female BNC connector, as my choice of lower loss coax was LMR-100 instead of the lossy RG-174 commonly sold as extension coax. Be advised though that you will need to order an additional SMA Male to RP-SMA Female barrel connector to attach standard RG-174/U cables sold on Amazon. Testing this out with my antenna analyzer and station monitor (equipment I have as an Extra Class amateur radio tech) the "real world" gain over a full-wave vertical antenna is about 11-12dB measured at the end of the SMA pigtail. Most of the advertised parameters are rubbish, based on a theoretical isotropic antenna. Much more loss occurs in the transmission line and due to each coupling loss. Don't want to scare folks here, but it is considerable and grows by every foot of line and connector or adapter. As is, I received a solid 4 bars on WiFi via an 802.11AC router, and the average send/receive was around 270Mbps into a WiFi 6 AX3000 PCIe WiFi Card. After a bit of thought, I built a crude small back reflector (8x8 inches) made from a bit of scrap aluminum sheet stock. This added an extra 2dB signal gain to the overall performance and 5 bars--which bumped the T/R speeds to a consistent 280-300 Mbps. I am well satisfied, both before and after my modification. I know that it would perform better if the router was AX compatible. Buy this with confidence, and don't forget to order a compatible Y-splitter cable to connect to your external antenna SMA connections.
