I'm interested in understanding the performance losses when using 75 Ohm patch cables vs 50 Ohm patch cables for receive only setups.
I've got three Stridsberg Multi-couplers that I use (1 HF and 2 VHF) that are fed using LMR-400 coax. They are patched to their associated radios via 75 Ohm RG-59 6 or 9 foot patch cables because they are easy to come by and they are inexpensive.
What are the downsides to doing this? What performance limitations should I expect considering this impedance mismatch? If there are performance considerations, are they different from HF/VHF/UHF and SHF satellite work?
The prevailing thought seems to be "it's not that big of a deal" - my question is, what deal is it?
