I've had the TinySA for a few years, and while I find it an overall valuable tool for lower frequency stuff (such as tuning CB and HAM antennas, along with my VNA), in truth it lacks any SERIOUS modern use beyond those categories. If you want to stray outside the UHF band, (the TinySA only goes to 960Mhz), you need something more capable.The TinySA Ultra IS that "more capable" tool. Going FAR beyond the sub-Ghz band capabilities of the old TinySA, this sweet little nugget of pocket technology goes all the way to 5.3Ghz, which means you can reach into the lower end of the 5G band, as well as everything from wifi to cellular with this.Now THAT, is a capable tool for modern antenna and Tx/Rx work. All you need is a capable VNA and you have an entire tool kit in your pants pockets. As one reviewer already stated, those of us who were trained in the military in "the old days" on equipment like this are pretty amazed at what used to cost $10k+ and now you can get for less than $200 bucks and you can stick it in your shirt pocket. It's astounding, the capabilities we enjoy today that simply didn't exist in any serious capacity at the consumer level 20+ years ago, not without a RIDICULOUSLY large investment. Talking in the thousands of dollars at least. Now, any kid with a paper route can have a serious antenna and radio tuning lab in his bedroom for next to nothing.Like the TinySA, if you've never used a spectrum analyzer before, there's a learning curve that can best be figured out by watching a few internet videos...there are plenty out there that will introduce you to using a SA, and many geared totally around the TinySA series in particular. When I was getting started out with "new tech", I found these video resources invaluable to learn my way around what is now "menu driven" but which I used to adjust with dials and switches. So don't be afraid to watch a few videos to learn your way around one of these powerful tools.If you've never used a TinySA product before, point blank, they work. Is it the literal equivalent of a $40k piece of equipment Motorola themselves might have in-house? Of course not. But for less than $200, it sure does get you darn close, and that makes it a heck of a bargain in my book. And a side benefit, it takes up VERY little space on my workbench, despite doing so very much. Now, I can start testing things like...cell phone emissions...and yes, even CB's & antennas...at much higher frequencies than ever before. I'm very happy to have this in my tool kit. If you do the kind of work that might involve using a Spectrum Analyzer, this is a fantastic piece of gear for the money. 5 stars all day long.

In the military, we had quite a few SpecAns we used and generally they were 10-20 years old, cost 10k+ or more at times and were about as big as a microwave. This little handheld I was hesitant at getting at first, but after I got it and tried it out, I'm glad I got it. Has a self cal port and a pig tail to go between to recal the equipment, sig gen built in, and one of the features I like on this software defined stuff is the waterfall you can put on to see where your hot spots on the freq band is. I'm slowly building up to get back into radios, I miss working on them in the military and plan on building my transceiver site here soon so I can start doing some ARRL
