Great little analyzer!  Time owned: 0 to 3 months
I bought mine from Vibroplex in the US, so shipping was ordinary. Analyzer comes with internal battery disconnected, you have to remove some screws and plug in a connector, this is probably for safety reasons in shipment. Performance is excellent, it is small, reasonably light, and very intuitive to use. Locate the manual online and play with it a bit, in 5 minutes you'll be an expert.
I've had an MP-1 antenna for years that I rarely use since it as the coil needs to be adjusted when you set it up and I find it a pain. With this little analyzer I'm up and running in seconds - great portable tool

Great When It Is Working  Time owned: more than 12 months
I own two of these, and when they are working, they are great, especially in the field. I bought both directly from the Chinese manufacturer. That said, both needed repair after some use, units out of warranty. After some research I found Yimin Zhao in Canada who appears to be the manufacturer's point person in North America. After a couple of emails back and forth I sent him both my analyzers and $50. And crossed my fingers. No further communication. Then several weeks later I get a package from China that included both repaired units.
They both were repaired and still work.

My perception is that this is a basically honest company that is way over its head in terms of customer service and marketing. Others have recommended going through Vibroplex to buy YouKits products. I agree.

Wonderful Antenna Analyzer  Time owned: 0 to 3 months
What a great little analyzer! I love the colorful graph of SWR and impedance and how it continually updates as you change the frequency.

This replaces my (more expensive) analyzer, hands down. Wish I had found this one first!!

Great  Time owned: 0 to 3 months
Great little analyzer. I have not checked it for accuracy but it looked good into a dummy load.

I like:
- Rechargeable battery
- Does not seem to be a battery hog
- Display is small but very easy to read
- Pretty ergonomic and has a knob rather than buttons
- Memories

Things I think could be better:
- It is easy to use, but I wish it came with basic instructions
- When I bought mine it didn't work out of the box. I pulled the cover off the back (2 screws) and saw the battery wasn't plugged in. Plugged it in and all was fine. Don't know if it was meant to be like that. No big deal.
- I wish it had a SO-239 rather than a BNC
- When you turn it off it doesn't remember where it was was when you turned it off. You need to reset the freq.

Overall I love it.

Compact, accurate and great display.  Time owned: 3 to 6 months
A very accurate and compact antenna tool. The memories for favorite frequencies is very convenient. The display is easy to read in almost any conditions.

The fact that the unit covers the entire six meter band is a plus, since most modern HF transceivers include the six meter band.

Self contained long lasting rechargeable batteries is a money saver as some other units tend to be battery hogs.

Operation is fairly straight forward and simple which is a plus. If it suits your needs it is highly recommended.

Compact, accurate, easy to read display  Time owned: 3 to 6 months
An accurate easy to use antenna tool. The bright display makes it easy to read. The memories for favorite frequencies are a plus. All this in a small attractive package with rechargeable batteries is very attractive.

I had an issue with the battery pack where it would not hold a charge within the warranty period. I contacted Scott at Vibroplex and he forwarded my concern to Yimin at YouKits. Ultimately the faulty battery pack was replaced and the unit performs as it should.

The customer service from Vibroplex and YouKits was very satisfactory. If this unit fits your needs for antenna work, it is highly recommended.

Good, but be careful if you take it out /p  Time owned: more than 12 months
Great piece of kit to quickly setup antennas, I've used mine for a Sandpiper MV10, worked like a breeze, and for setting up a cobwebb and several linked dipoles...
But beware... Especially if you take it out /p, with an internal battery.

The crystal on the internal PCB is higher than the rest of the components on the board, unless you ensure the battery is secure inside the box, it WILL rip off the crystal, and the associated PCB tracks!

Cannot be without this  Time owned: more than 12 months
I agree with the previous review. This is an amazing, must have tool that any ham should have. Far better than my Comet or MFJ antenna analyser.

To a previous review, I have never needed customer support, so I cannot comment. In the two years I have owned this it has worked like a Swiss watch. Regarding RF noise from the charger...I have never noticed any RF noise across the spectrum of my Flex radios. Besides, even if there was noise....I only charge my unit once every 6 months - that is how long the battery lasts between charges, that it would never be a problem anyway. A charge takes just a couple hours. I don't leave my analyser on for any extended period - it gets switched off right after I have done tests, and the 6 months between charges is very conservative....I recharge it long before it needs a charge.

I have a very accurate LP-100 digital vector SWR/power meter. I have compared this analyser to my digital vector well as other known impedance sources, and the accuracy is spot on. Far more accurate than any of the run of the mill analogue SWR meters out there.

I cannot comment regarding BNC connector or multi knob becoming loose - mine is still as firm as the day it was bought.

To sum up, this is a really handy, solid and accurate analyser. And the factory battery seems to last almost forever between charges. This is one instrument I would not be without.

Accurate   Time owned: more than 12 months
An update to my previous review.
I now have an Array Solutions PowerMaster installed in the shack and have run a number of tests tuning the DB-11 with the YouKits and checking them with the PowerMaster, which is lab grade certified.
The results are impressive as far as vswr is concerned. What the YouKits tells you the vswr is , is what the powermaster measures.
I rate this little box of tricks highly with the rechargable battery pack it is a reasonably priced pocket analyser.

No support from manufacturer   Time owned: more than 12 months
I've owned this product for about two years now so it's time for an updated review.

The sole US dealer was previously Ten-Tec. Now it's Vibroplex. There is absolutely no support available from the manufacturer. When I attemped to contact the manufacturer about some issues by using the form on their web site, they did not even reply.

The good points:

1. The FG-01 is easy to understand how to use.
2. It's one of the cheapest antenna analyzers available.

The not-so-good points:

1. There is absolutely no support from the manufacturer. No phone number, no email address.

2. The battery charger generates stronger and broader RFI than any product that I have ever encountered. I tried contacting YouKits by using the form on their web site and received no reply. I emailed Vibroplex for help and they told me that "the manufacturer is a bit slow responding to them." Slow is right -- about three weeks so far. Vibroplex told me that they are trying to locate an alternate charger that does not exhibit the RFI problem, but they have not come up with an alternate charger so far. It's bad enough that the manufacturer is selling this high-RFI charger at all, but to sell it to ham radio operators is beyond disgraceful.

3. The product looks rugged but actual use reveals that it's not that rugged after all. Even after very careful use -- with a BNC to UHF adapter always attached -- the locknut (on the inside of the unit) that secures the BNC connector became loose. It was easy enough to tighten, but it shouldn't have become loose in the first place.

4. Another issue is that the combo push-button/rotary control failed when the unit was out of warranty. The manufacturer does not repair these units out of warranty, even for a fee. With great difficulty I was able to repair the unit myself. In general, though, this should be considered to be a $260 "throw away" if it fails after the one year warranty is up. (Would you expect to trash a $260 2 meter rig if it failed after its warranty was up? No, of course not. Reputable manufacturers provide out-of-warranty service. It might cost a fair amount, but not as much as a new rig.)

5. The unit is useful for helping to tune antennas, but it's not anywhere near as accurate as an SWR/wattmeter. Before using it to trim a dipole, check SWR or reflected power with a good SWR/wattmeter.
