RF Detector?

Is there a handheld device to detect RF and where it is emanating from? It would be helpful to show signal strength to pinpoint direction and closeness. Hell, it would be a bonus to show the activity/events of the RF in real time as well.

Any suggestions?
 
Any frequency that would interfere with the normal operation of electronics equipment. Possibly 1Mhz to 3Ghz?
 
Maybe I'm just paranoid, but I have a feeling our property is being bombarded with RF to jam/interfere with electronics in our dwelling. I can see a large coil of wire leaning against the fence at the neighbor's house across the way facing us. That is relatively new addition.

There has been some random odd equipment behavior that I cannot explain which coincides with when that coil first appeared and none of the equipment is connected to the net. I just want to find out if there is an unexplained presence of RF and where it is coming from

Then again, you could go ask the neighbor what's up?
This is the same guy who has 6 IR panels on his fence pointing as us. Since I'm running in color, they don't make any difference to us. He does NOT want us to have cameras which captures any part of his property. The guy never leaves the house since last year. He really needs to see someone. He's got a couple of screws loose.

I won't set foot on his property as he would likely trespass me

I just want to verify the RF issues exists and its origin so I can contact the FCC
 
It's going take some time to go through the options on Amazon. Seems like many of the detectors are geared toward finding bugs and spy cameras. I want to sniff out signals from 100 feet or so. Frequencies from Khz to Ghz. It would be nice to have a real-time monitor of RF activity so I could match up a random event with the spike in RF and record it as evidence
 
N9010B EXA has a nice Signal Analyzer that goes from 10 Hz to 44 GHz. If higher frequencies are needed, then another analyzer will be needed. To buy you are looking at $35K plus.

Suggest renting for a day to keep costs down.

If a large coil of wire were hooked to a power supply, it would generate a magnetic field that could interfere with radio signals. Like driving under a power line interferes with the AM band. I don’t know if it could be tuned to certain bands. I do think that interfering with radio bands is an fcc offense and they can track down the interference.
 
I wonder if you reach out to the FCC, would they investigate with their equipment?
The FCC has little interest unless there a proven RF interference issue caused by a radio operator (think ham/amateur/CB) radio. There would have to be a consistent cause and effect and directly pointing to your neighbor.

If others in the neighborhood are experiencing similar RF issues at the same time you are, then there is a chance that a problem exists. The issue could be with your neighbor or with some other facility producing RF interference.

Would suggest you log dates, time and a description of the issue. Then check with your other neighbors to see if the same patters exists at their location. RF in general spreads out (radiates) so if you are having an issue others are most likely too.

Yeah, I've dealt with the FCC before back in 2020. If you have no evidence, they don't want anything to do with it.

This is why I would like to verify if RF is being emitted and where it might be coming from.

If I can find a unit to monitor rf in real time, it would show activity that may coincide with the random issues cropping up.

Other than the guy I suspect may be causing the issue, I would say everyone else in the neighborhood wouldn't suspect foul play and chalk it up to service disruption

Ok, I'm curious, has your neighbor explained what is up with the IR panels? What has he told you? This seems like it may be a matter requiring good communication and working together before things get uglier.

I have a camera pointing towards my neighbor's house. I have absolutely no interest in capturing their property but it is in the FOV of mine and the street, which I am interested in. Because I believe in privacy rights and being a good neighbor, I would work with them if they brought it up as an issue. But that's me and I'm a nut. :winktongue:
 
A spectrum analyzer is what you need and it is not necessarily an easy tool to learn to use. As was pointed out, a high quality test unit is very expensive.
Here is a low budget device could possibly be used:

RF Explorer ISM Combo PLUS - Slim

There are several models depending upon the frequency ranges you want to monitor.

If the neighbor is broadcasting a strong -wideband signal a unit such as this one may be able to capture it. That said it is not an easy tool to use. You need to test over several frequency bands individually.

It's a long story. But I'll see if I can summarize.

Back in 2018/2019 neighbors were friendly to the wife and I. The same guy that is giving me trouble now, played the victim that his next-door neighbor was doing what I suspect him of doing now (starting to see the picture?). Those two had constant issues (cameras, lights pointing at each other) and he complained that his neighbor was causing his service disruptions.

His neighbor worked for Spectrum as a technician. He decided to sue his neighbor and the company he works for and solicited other neighbors to testify on his behalf. All the time telling everyone he was the one under attack. So, few of us took the bait and testified via zoom in early 2020. It was a miserable failure on his part. It was all heresy testimony and Spectrum's lawyer made all the neighbors and him look like complainers. Judge ruled in Spectrum's favor.

After his loss, he and the neighbor turned it up 100 notches. It was a daily fight on public display. Both would stand outside with handheld devices hell bent on disrupting service. Unfortunately, it also disrupted everyone else's service. It got to the point that I couldn't use the internet regularly which my business is an online store.

The neighbor who lost the suit suggested I switch providers from Spectrum to ATT. So, I switched and the internet disruption went away for me in April 2020, He was my friend, right? I had to trust him, right?

The feuding went on until late 2020 when the Spectrum guy and his family sold their house and moved. We all thought it was over.

I installed cameras at the end of 2020, beginning of 2021 because of crap happening in the neighborhood. It was great, our hibiscus flowers were on the ground in the morning and not gone like before. It was all good. Then I would have random PTZ camera movements at night while sleeping. I would wake up, check the live feed and my one PTZ would be pointing down at the ground. And another camera would go black and then come back on and repeat. So, I disconnected net service and that issue stopped. Unfortunately, I lost remote viewing and notifications.

But then the issues reappeared, even with the net being disconnected. It was then that I found out he was accessing my network through the Wi-Fi connection on my laptop. I disabled Wi-Fi and used the ethernet connection. Stopped for a while and then new issues. That's when I purchased an external router and put the ATT modem in pass-through and disabled Wi-Fi on the ATT device. At that point, I knew the problem was local. I then realized, it was the guy I'm having trouble with now who was the problem, not the Spectrum guy who left.

I'm not sure why he is hell bent on others not having cameras. None of my camera equipment is connected to the net, but the strange issues still happen. With the coil of wire he has, I'm thinking he may be using it to bombard us with signals causing the issues. I'm unsure, so I would like to test with a detector/scanner/spectrum analyzer to know for sure
