I have this weird problem, I connected a new EFHW antenna, EFHW-8010-2K-Plus, to my Icom IC-7300. When measuring the SWR, the IC-7300 SWR meter indicates a low SWR, but my Daiwa meter indicates high SWR, but when my IC-7300 SWR meter shows high SWR, infinite, the Daiwa meter shows very low SWR, around 0.5. If I add a tuner things get more crazy but still the same pattern. IC-7300 SWR meter high, Daiwa low, IC-7300 meter SWR reding low, Daiwa reading very high. I use a MyAntennas EFHW-8010-2K-Plus antenna without my tuner. IC-7300 -> Daiwa 501 Meter -> Antenna. Antenna is over my roof in a inverted sloper configuration, transformer higher that the wire’s end. With my Chamaleon CHA III, any of those problems disappear and both SWR meters show almost the same readings. Thanks for your help!
