DB11 Yagi Antenna – Steepir

With the DB11, you don’t have to give up performance to fit the antenna into a small space!

The DB11 is the smallest of our Yagi antennas that uses loop technology.  This is a distinctive advantage, allowing for a 40% smaller size platform with excellent performance.  The DB11 uses an integral coax switch to select which one of the three elements are driven to give equal performance in forward and reverse directions. The control of the Antenna and Coax switch is integrated into the SDA100 controller for effortless tuning.  The DB11 is our only antenna without the optional 6m passive element kit – the spacing of the 3 elements turns out to be ideal for 6m as well.

With two active elements on 20m and three active elements above 20m, an average of 7 DB of gain, and 20 DB front/rear ratio is obtained on each band.

FG-01 Antenna Analyzer – Ten Tec

Description

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.  We suggest you order the optional Lithium battery pack R9411 (18650). The charger provided with the FG-01 will charge the R9411 (18650) Lithium battery.  With no battery you can use a quality regulated power supply such as the TEN-TEC model R4005.  Batteries are not included for the battery case shipped with the FG-01.

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.
