Highlights:

1: This tuner tunes almost everything. On the low bands your wire should be a little longer for better performance

2: Super performance due to smaller capacitors steps.(9pF)

3: 3,5 - 52 Mhz. ( 160 meter possible with long wires but not supported)

4: Direct control from most models of Icom and Kenwood

5: This tuner you can use on any radio with the control box (included)

6: Extremely good performance for mobile operation of small balcony antennas.

7: 50 EEprom memories (so no battery inside)

8: Also extremely usefull for mobile and portable HF operations

To connect any radio you can use this controller (included with every tuner) For the most Kenwood and Icom types this controller is not needed for normal use.  You can also see how simple it is to start the tuning process or to switch the memory use on and off. On purpose we provide a very cheap control box. You can change to any design you like.

Heredown we show an example of a Kenwood tuner connection on the back of a TS-590. With this connector connected directly to the outside tuner you do not need to use the provided control box like the picture here above.

Example: a home made dipole with end loads 2 x 2,5 meters long, 2 meter from the ground : It tunes from 3,5 Mhz untill 50 Mhz !

Example of testting a mobile whipe on a Balcony. This whipe is just 1,5 meter high.

It tunes easy from 3,5 Mhz - 29 Mhz (tested) Ofcours the performance on the lower bands is limited but if you have

limited possibilities this is also a great solution, (In the back you can see a element of a A3S beam)
