9dBi WiFi Antenna with SMA Male Connector Compatible W/Anran Haloview IP Camera & Other Wireless Security Camera Antenna - 2.4Ghz Wireless Networking Device (SMA-Plug 1Pack)

Upgrade for my fireworks firing system. Works great and added significant distance to reception of system.

El producto parece bueno pero la descripción estaba mal y las antenas no se pudieron instalar en mi equipo. Las regresé-

Maybe I didn't read the description, but the antenna was longer than I was expecting. Tried it out (remote wifi camera) and it worked fine with a 5dB increase in signal stength. Problem was it's outside in a windy location and the wind keeps blowing the antenna to point downwards into the metal structure below that impedes reception. Nothing to do with bad antenna design etc, just my particular situation.I found an old cable and fitted a patch antenna to the camera that gives about the same signal as the Techoo antenna when vertical (tells me the techoo antenna was working well)I'll keep it and might have use for it if I find an application with a reverse SMA connector in a more stable environment. :)

good delivery time, works goodI put this on an ESP32CAM after changing the board to accept an external antennaThis procedure is well documented on the webRESULTS from RSSI readings off the ESP32CAM:before - RSSI from the ESP32CAM was -70 to -87 on my deskafter - RSSI is now -49 to -53 on the deskThe difference is huge but this allows me to use the ESP32CAM 120' out at a shed where before the "mod",it wouldnt connect to the wifi router in the basement (even at 50' out).Now it is almost the same strength way out there (-87) as what the board without the antenna mod was sitting on the deskI also tested the connection RSSI out at the garage where there was no connection before, now its in the -70's which is very goodI would really recommend this antenna even though its about 15" longBest RSSI strength is when the antenna is vertically positioneddefinately a 8 star is there was such a rating

Used on my wifi backup camera and it made the signal much better, dropping the connection much less. It is a bit long at the elbow and I had no space in between the camera and the RV wall but I used a 90 deg adapter to make it fit. A good buy.
