FG-01 Antenna Analyzer 1-78 MHz (INCLUDES BATTERY)

TEN-TEC is proud to announce that we are the exclusive distributor in the US for YouKits brand products.

The first product we are introducing from YouKits is the FG-01 a 1 to 60 MHZ Antenna Analyzer. This is not a kit but a fully assembled unit ready for use. The FG-01 utilizes the latest in SMT technology to provide a compact unit with lots of value.

This antenna analyzer is the smallest (measures less than 4“ tall) and easiest antenna analyzer to use on the market today. It has a color display that graphically shows you the SWR and Impedance of the antenna under test. This unit is right at home being carried to the top of the tower or on the bench in your shack.

The FG-01 with its color graphical display allows you to dial in the frequency you wish to operate on and immediately read the SWR and Impedance of the antenna at that frequency. The FG-01 also allows you to easily adjust the frequency to determine the desired SWR points of the antenna. For instance if you wanted to know the 2:1 limits of your antenna you would just change the frequency using the large knob to move the graph to the 2:1 point on the center of the display and read the frequency.

No more guessing where the low SWR point is on your antenna. No more guessing about you antenna characteristics, you just read the SWR and Impedance on the color graphic display or look at the curves to fully understand the characteristics of your antenna.

The FG-01 comes with a wall mounted Lithium battery charger and as of May 1, 2014 is now sold with model R9411 Lithium Batteries included for the FG-01 at a new price.

This unit is sold exclusively in the US by TEN-TEC and has a one-year replacement warranty. This unit is not manufactured by TEN-TEC therefore the non TEN-TEC manufactured return policy applies.


Note: The knob on some of the later model units may be chrome or silver instead of black.

  1. Perfect for travel

    Posted by Cliff N4CCB on 29th Nov 2013

    I've been using a big, clunky MFJ-259B - even when traveling. It works great but it's 4x bigger than the YouKits analyzer... as big as my KX3!

    I'm very impressed with the YouKits analyzer. It's simple to use and works great. I wish that it included a BNC to SO-239 adapter... although I had a couple laying around.

    If you travel or like to work portable, this is a great piece of gear!

  2. A great liitle antenna tool

    Posted by Evan WB5KOJ on 26th Sep 2013

    This thing works great. Easy to use and dead on accurate. The display is sharp and bright. The graphical display is a much better way to see what is going on than other units that just give you single point numerical data. I recommend buying the internal battery pack (don't know why it does not come with that as standard). For the money this one is hard to beat!

  3. FG-01 Antenna Analyzer my new Toy

    Posted by Merl Hoover on 25th Sep 2013

    This product is so much more than you will expect. TEN-TEC might consider upgrading their utube video and brochures. My unit is one with some upgrades from those indicated. The SWR Column now has 2 digits 1.0 1.5 2.0 3.0. the menu now has an indicator for storing and selecting MEM 0 thru 9. just above the Battery Indicator. That Column has been adjusted to align with the column on the left. Apparently the font size as been adjusted to accommodate these changes. The documentation is sparse. For me or many it will be a handy tool and a learning Aid. I have found myself thinking of the SW as a zoom feature. There is no instruction as to installing the Optional Battery or the supplied battery case. The battery use is longer than I had expected, but keep aware of the warning re the recharge point.
    When you determine that the back has to be removed to install the Battery feature, be AWARE THERE ARE TWO (2) screws to be removed. On my unit the top screw was covered by a sticker MADE IN CHINA. That caused me some difficulty. There might be additional features in the future. A USB PORT, for upgrading the software, and transferring data or instructions as to how to make a connection to a Pc for software upgrades. IT IS A KEEPER +++

  4. Amazing little Unit

    Posted by Andrew Knittle on 16th Sep 2013

    I have used my friends MFJ, but decided it was time to own one myself. I am partial to Ten Tec so I checked out the video review and decided to give it a try. I was blown away ! How neat is it to see the entire SWR spectrum and impedence on a graph. It makes adjusting an antenna a breeze. Without a doubt the best analyzer on the market. Make sure to pick up the internal battery and the BNC adaptor.

  5. You don't have to be an Antenna expert to benefit using this!

    Posted by Dick on 10th Apr 2013

    I have used another antenna analizer, but this is sweet,small and handy. It is simple to use and a well designed, useful tool for any Ham. I consider it a great tool.

  6. Worked Great For A Year, Now No Service

    Posted by Mike, N7DGI on 3rd Apr 2013

    As others have noted, this is a great product that does an excellent job. Until it quits after your warranty is out, then Ten-Tec doesn't service them, just "throw it in a box to go back to China, don't know how long or what it will cost". So, $250 down the drain. Buyer beware!

  7. FG-01 Travel Review

    Posted by Bill K6ACJ on 17th Feb 2013

    After 6 trips to various California and Arizona Desert Campouts plus local trips to the beach, the FG-01 has performed flawlessly allowing me to rapidly deploy my various HF antennas and switch bands then retune in seconds. The bright color LCD does not wash out in bright light like my iPhone. I am using my own Lithium batteries and the supplied charger without problems. Yes, like any antenna analyzer it will pick up strong EMI/RFI but it worked fine at Quartzfest and Yuma Hamfest where there were many stations on the air.

    An improvement could be made to rapidly set the center frequency but its not a problem as-is and the BNC is not a problem because I use a high quality pig tail with SMA adapters.

    Battery life is longer than I thought it would be, 1 charge worked for 5 days at Quartzfest and 2-1/2 days operating at Yuma Hamfest.

    I'd like to see a robust and small carrying case with just enough space for the charger and a coax pigtail.

  8. Power supply

    Posted by Miguel, LU1DO on 5th Feb 2013

    Power supply delivered with FG-01 causes noisy signal to be shown on the lower HF frecuencies, changed to a linear power supply and I get a smooth curve.

  9. Beware, it gets warm...

    Posted by Miguel ,LU1DO on 5th Feb 2013

    I use a FG-01 almost every weekend and learn a lot about tuning my wire antennas.
    What really needs a revision by the manufacturer, is the fact that the FG-01 gets very warm in relative short time. This forces me to wait till it cools off to a reasonable temp.

  10. Technology at its best

    Posted by Jim Ashby, K5JCA, WCARES Utah, USA on 14th Jan 2013

    I had an issue with my FG-01 failing hours after first use, replacement was received, and now I am back up and running. It was kind of like teasing me into wanting more. The unit works as described, and it does it well. As an Electronics Engineer I was ready to design my own device, but with the cost of the FG-01 being so low, I decided to purchase one and give it a try.
    I was surprised to find the FG-01 easy to use and the display give me all of the information I need to tune my various antennas. Within 5 minutes I was able to retune a random length wire antenna to tune away from the Ham bands which allows my auto-tuner to optimize the operational bands. The antenna was tuned in the 40m band and I was not getting good performance in the 80-20-10m bands, now it tunes all four bands well.
    Now to build a variable length wire antenna and get it up in the air.
    Thank You Ten-Tec! 73
