TECHTOO WiFi Antenna

I bought a pair of these to modify a Klark Teknik DW20 professional audio link for greater range. The stated Line-of-Sight range is 100ft, I was able to hit 230 ft reliably in an open area. Using the pair TECHTOO antennas, range jumped to an incredible 1150 ft reliably, with 1170 ft being the upper limit with a semi-clear LoS.

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.

The antenna arrived in perfect condition on the promised day and well packaged in a box within a larger box. It is of high quality all-aluminum construction and well-suited for its job as an outdoor antenna. The mounting hardware is steel and fits my J-Mount kit (also from Amazon). As mentioned by other reviewers, the antenna is highly directional. For the initial setup, I will be using a small laser pointer temporarily attached to the main antenna beam support to get the antenna closely aimed to the target router’s antenna location. Fine tuning will be done with the signal strength indicator on my receiving computer’s wireless interface. The final setup will be a bridge, but using the antenna initially as just a range extender for a single computer simplifies troubleshooting. The antenna does provide gain, but is best used where interference is more of the problem. This isn’t my first rodeo in this.

It worked how much better was it for why I was buying it and how it works hard to decide maybe my router couldn't pump out enough juice to get what I was trying to do is that room, respectful I have to play with it more it also had a chip on the tip of where the plastic Square cap is

Mounted the antenna on the outside wall of the shop with a wi-fi adaptor . I use a long USB cord to bring the signal in to the computer. It can receive the house modem signal from 600ft away. Satisfactory....

surprisingly good.

About 200ft from the wifi source, my cell phone on wifi was able to pick up signals but spotty. Tried this antenna with Dlink Dir655 (n type), and Linksys wrt54g (g type), neither got signals. Not sure if I was unlucky getting a lemon but going to return it and look for something else.

My brother in Christ I can pick up the wifi down the street. Which means when I'm sitting in my white van and surveiling suspects I can literally dos them while deploying a captive portal it makes catching bad guys so much easier... I use it daily lol 😅
