Title: Source for used semi-rigid coax with SMA (odd ends)?
Post by: cdev on January 27, 2016, 04:06:54 pm
I want to make some small projects like probes and loops, etc, that really need to be made with semi-rigid coax to not be totally half assed, but its always been my perception that getting into semi-rigid is expensive.

But I am not some kind of scientist looking for absolute perfection. I am not looking to do work with microwaves presently or need the absolute best performance, I just want to be able to make some small antennas and pickup loops that aren't floppy for picking up EMI, experimenting with RF and so on.

Is there any place I can buy maybe used or surplus odds and ends of semi-rigid using cables? Other people's garbage.

Typically they will be short and only one end is going to need the connector.

Have you checked E-bay?

Awesome - thank you!!! problem solved.

No, I had not seen that the last time I went looking for coax on ebay. Which was a long time ago.

   A LOT of stuff like that shows up at hamfests around here.  I have a whole tote bin full.

Hi

A lot of it shows up *inside* gear abandoned at the end of ham fests. Grabbing old gear and salvaging the parts is a very cost effective way to do some of this.

be careful with some of the Chinese SMAs, the centre conductions should be hard, springy BeCu, but instead it's soft brittle brass
