I just for this 50W 50 ohm dummy load. XRDS-RF from Amazon. I directly connected it to my SureCom meter, no cables and no adapter needed. I keyed up and read both wattage and SWR, the SWR shows 1.7 which is higher than what I get through my outside antenna with 45 feet of cable! Is this just a bad dummy load or am I missing something. I expect 1.1. I measured the resistance using a digital ohm meter and it read 49 ohms.
Why am I checking SWR? To use the dummy load to measure line loss of the cable. Professor Ed Fong told me it would be good reference to measure the SWR introduced by the cable and measure again with the antenna. This way, you can tell what is contributing to the overall value.
I know there are a lot pricier dummy loads, is this brand/unit bad?
