We have large conveyor carts that run along a straight track in our factory. Right now they are controlled via industrial routers. The little omni-directional antennas don't handle the distance very well (up to 200').We have tried running cable but that didn't work well because the cable is constantly being flexed when the carts are moving. I did notice they used solid core CAT6 cable rather than stranded, so that would explain the signal interruptions using the cable.I'd like to try a yagi or similar narrow beam antenna to see if the connection will be more reliable. Since this is just an experiment at this point and I don't want to spend a lot of money just trying different models, does anyone have a suggestion for a suitable antenna? I almost hate to start the Ubiquti bandwagon, but given the relatively lost cost and reliability I've seen from their WISP gear, I'd consider seeing if I could adapt one of their sector antennas to make this work.

It's almost total overkill for just 200' but low transmit power and keeping things to either 30- or 60-degree bands might do the trick.Do you know what the sensitivity/gain is on the current antennas? That might help us find something reasonable without being too pricey or too overbuilt for such a short run. I wish I had more experience with the wireless stuff on the plant floors but another team tends to handle that here and I suspect that my client doesn't question paying the thousands upon thousands to get this working.

Right now they are only rubber duck omni-directional antennas, so hopefully anything directional will be better.At the cart end, the rubber duck is mounted right on the metal console, which is probably not a good mounting point - acting like a ground plane.

I would mount a new antenna on a post so it's right off and above the cart.It's been Some Years since I did radio theory, but I'm pretty sure a vertical antenna having a large ground plane is generally seen as a Good Thing. Robert762 wrote:I wonder if just using the amplifier to bring output to 500mw would make the difference?Probably. I'm no RF engineer and going on half-remembered training around electronics in general. But.it's been my experience playing around in the consumer wireless space that the remote Tx is what is usually lacking.This is where it would be really nice to have a real spectrum analyzer and not have to rely on my phone apps to try and guess my way through it. Austin's probably right though. My gut tells me fixing half the equation will probably get it working but amplifiers and better directional antennas is probably going to make it a lot more robust without a huge time/cost investment.

Nothing could be simpler to build than a 2.4GHz yagi. You can make one out of a wooden dowel and some tin. Or even cardboard with copper tape on it.The only thing you'd need is an AP with a connector for an external antenna and a compatible connector/cable to run to the array.A simple corner reflector will focus all the energy forward and give you a 'virtual' array. It's probably the simplest way to determine if you're going to get the results you want.

Run a test without, then with. See what sort of range improvement you get.

Then, if you need more, move to more complex designs. Hi Robert762You can also have a look at what Cambium networks have to offer their equipment are robust and offer a range of different antenna configurations, we have lot of them in the filed for backhauls or PtP or PMP, their range are really good and not as prone to interference as theUbiquiti Networks equipment. Make no mistakeUbiquiti is good but in my opinion the cambiums are just a bit better, as their roots started out from Motorola solutions.Here is the link to their product range have a look im sure you would find something that is fit for purpose. So, one thing to remember - Wi-Fi is a two-way communication. Any antenna amplifies the Tx and Rx (though in some cases, these radio chains are separate), but it also amplifies noise. Successful Wi-Fi relies on effective SNR. Hanging an amplifier on the transmitter will amplify TX signal.

Hanging it on the Rx side will amplify BOTH received signal and received noise, leaving the SNR effectively unchanged. The challenge with all Wi-Fi is the receive side of the equation. Typically, clients (phones, laptops, in this case, conveyor carts) broadcast a return signal that is anywhere from 50-90% lower than the AP. That's how the signal indicator for Wi-Fi on your phone can have '5 bars', and yet the performance sucks (an industry term). For this case, I would leave the amplifier off, get a moderate gain (14-18 dBi) 90 deg antenna, and see how that does first.My $0.02.
