Foundations of Amateur Radio – Episode 145 Coax Loss vs Connector Loss

A question that comes up regularly is one about loss, specifically loss in the coax and connectors between your radio and your antenna. The general wisdom is that better coax gives you better results and more connectors is bad.

Anything with double joiners, or such like is really bad.

So, essentially we’ve been taught that we should have the shortest coax possible with as few connectors as possible.

Pretty fair and reasonable, right?

During the week I was introduced to a video made by Jim W6LG. Jim has a YouTube channel going back a couple of years with about a 100 videos.

One video is loosely called Jim measures the loss in coax connectors and 100 foot of RG8X. In case you’re wondering, 100 foot is 30m and 48cm of coax. I know this because the United States of America despite appearances to the contrary is actually metric, they defined the inch as being 2.54cm back in February of 1964. Other than driving on the wrong side of the road, they’re not too strange and they talk on the air, a lot, so there’s that.

Back to Jim.

He rummaged through his bits box, the one you have, the one that every amateur has, and if you don’t then you clearly need to spend some time being with an Elmer and learning the ropes. Jim pulled out 30 odd connectors, SO239 and PL259 by the looks of things and daisy chained them all together. Jim has been around the block a few times and he has connectors going back to World War 2, so he really did find the bottom of his box to make his video.

Anyway, he rigged up a testing tool to compare a single connector to 30 connectors. Measuring the difference, (more…)
