Re: High SWR on all HF Bands

With a pure resistive 50 ohm dummy load the impedance seen at the SWR meter or radio will not change significantly with different lengths of coax, assuming the coax is close to 50 ohm Z.  

It will change when the  load impedance is different than the coax.    Of course many 50 ohm loads are not really 50 ohms at RF, even if an multimeter says they are OK.  If the 259B measures the dummy load as 50 ohms non-reactive, then it is probably OK.
