Antenna Analyzer, FEATURE TECH AW07A HF/VHF/UHF 160M Impedance SWR Antenna Analyzer Meter for Ham Radio Hobbyists DIY

I bought the AW07A as an alternative to the MFJ-259D because it covered 440 Mhz as well. But to my disappointment after a short while of usage the VHF and UHF portion failed to read. When turned on all it reads for VHF and UHF now is Frequency error or Output error on the top line while the SWR seems to be reading something correct. Problem is I have know idea where on the frequency spectrum it is reading. My advice, shop around more and don't buy this Chinese garbage.
