I'm glad you commented about the loss.? I can't count the times I have heard that connectors add loss, anywhere from 0.25db up to 1db per connector.
Jim W6LG, has a couple videos on his YouTube channel about this topic.? He uses 20 various connectors, all attached to each other, and uses a RigExpert meter, the loss was something like 0.12db if memory serves me correctly.
That being said, using cheap, bottom of barrel connectors, I would suspect that you would see some loss in db.?
A situation arose, where I had to make a repair to my 75 ft feed line for my 2M/70cm rig.? It got severed about 20 ft from the radio.? I soldered on new connectors to each end and used a barrel connector.? I didn't do any measurements in db but my SWR was the same as before, same forward power and reflected.? That example might be like comparing apples to oranges in a way but if I measured the db, I don't think I would see any meaningful loss.
