Warranty

 

We provide a two year warranty on factory 
defects of the HF analyzer, the antenna and 
accessories.  

The analyzer is not impact proof, due to the 
comparatively heavy battery and the large 
number of wired components. 

Any damage as a result of misuse is ex-
cluded from this warranty
