Watching a TV Antenna FM Filter in action on TinySA Spectrum Analyzer

- Observing OTA TV Antenna FM Trap results on a TinySA Spectrum Analyzer. I picked up a TinySA spectrum analyzer from Amazon, and it’s a handy little tool for a DIY’er because you can actually observe the RF spectrum and how various various filters such as FM traps or 5G/LTE filters make a difference in calming sources of over the air TV antenna noise and interference.

We used to use the radio shack versions of these with pioneer cable boxes
Cool. Was Pioneer a cable company?
@@NorthcoasterHobby Pioneer the big radio company made the model BA-6310, that was used in my area. It received its 'commands' from the headend at 110MHz. Without a trap it would die overnight, it would last weeks with it!
@@SilvaD702 Thanks for the info!
I use the AMIKO TSC1270 digital meter for satellite, antenna , digital and analog cable instalation (two inputs one for satellite and the second for cable/antenna). My digital meter also has a spectrum analyzer. On the spectrum analyzer I see that I have signal on both FM and UHF band I can also zoom in and I can see how many Db I have on each frequency. Interesting part is that if I go to analog cable installation, I can manually add a frequency between 40 - 1100 MHz, by default it has the 105.25 MHz frequency set as channel 4, I also added the 82.25 MHz frequency as channel 3. If I connect any FM antenna the signal strenght in most cases is 100%, but if there are some problems with the antenna or coax cable the signal drops, if the antenna is indoor the signal is 70-80%, if there is no FM present or an FM Trap is installed the signal strength is 5-10%. I use this feature when I install an FM antenna to check if it the setup is correct or everything is allright. For better testing i recommend an FM radio with coax input The TSC1270 is not designed for FM installation only for TV but this is a hack. If you use it in North America you can use it as a satellite finder for both C and Ku Band but you must delete the European satellites and add North American satellites, adding a satellite or transponder is the same like a satellite receiver, unfortunatelly you can't use it for digital cable and antenna beacuse the tuners is DVB-T/T2 and DVB-C/C2 but you can use it for analog cable just change from PAL G to NTSC.
Good to know. This analyzer also has the option to dial in a frequency and observe the SNR and other measurements. I wanted to keep the video as straightforward as possible.
Can you do an unboxing and review with your analyzer?@@NorthcoasterHobby
@@Nicholas_Chris I will soon, going to get more acquainted with it first though.
If you are here reading comments, you might be having reception problems. Here are a few more tips that could help. Use an AM radio tuned to static to sniff out electronic noise around the house. Cheap LED lights, dimmer switches, and transformers can create electronic noise that can interfere. Another easy way to see if this is the problem is to turn off breakers in the breaker box.
Cheap led lights are notoriously dirty too with stray rf as well as some fluorescent lights.
Holy smokes what a difference!
Gives a visual of the attenuation of FM signals, and some tangible evidence that filters work!
Means nothing unless you have a local TV broadcaster at RF channel 6 that you are trying to receive.
@@jimross2101 FM frequencies and their harmonics can affect other parts of the TV band. Example: 88 MHz has a 2nd harmonic at 176 MHz, which could affect High-VHF channel 7. There are other harmonic frequencies across the FM band that could affect RF channels 7-13.
So it’s not just channel 6. Plus the video it shows the filter does what it is designed to do.
drag the marker along he signal line ,or use the jog button on top, easy.
I’m still learning.☺️
Im reluctant to spend $25 for an FM trap without proof of improved TV reception. Also, I have just learned that they make sat receivers that allow you to get all of the same OTA stations for free with a dish. Nice......no interrupts from either 5G or FM. They are cheap too.
I’ve you’re referring to free to air satellite, the channel lineup varies. Don’t expect to regularly find free network channels, most are encrypted.

I wonder if those are shortwave signals on the far left side of the graph.
You live in one of the few areas where you can demonstrate how low VHF and high VHF straddle the FM band and how narrow the FM band is.
It seems weird that the manufacturer didn’t use standard coax connectors on that analyzer.
An interesting video for you would be to connect a small dipole to the analyzer and go around your house checking LED bulbs.
I never thought about those signals being shortwave, good point. I’ll try the dipole idea around the house.
Those small coax connectors are called SMA and if you dont pay attention, when you buy some of the fm and 5g filters, they might arrive with the SMA fitting.
Can you please do a review on the Tablo 4th Generation Over-the-air DVR?
I’d like to, and I’ll look into it. But the issue is that the free streaming channels available on it would be geoblocked in Canada, where I live.
@@NorthcoasterHobbyyou could just do a review on it, and simply say it includes streaming channels, and not show them one.
@@RockysFunAndHelpWorld I will look into it.👍
Can it actually view the station tho?
No.
@@NorthcoasterHobbyok
