I received a sample of low-cost SMA cables and connectors planned to be used throughout the HFSP PRO 100W AMP V3. I had worry that the cost was going to be prohibitive.
The Pigtail SMA Male to Male cables are semi-rigid .141” wire and excellent workmanship. They mate up nicely with the SMA through hole Jack vertical PCB mount connectors. It looks like a good source for the project. The cables are available in various lengths. Cost is $5.20 for the 6” cable and two connectors in low volume.
I am pleased with what I see. Response and delivery from the vendor was very fast.
