A few days ago, I noticed that the SWR on my 2-element quad was fluctuating. I brought the antenna down, and found that the problem was the connections on the 75 ohm impedance matching jumper. I am using CommScope 75 ohm commercial cable tv coax for the jumper because I have a reel of it on hand. I modified a RG58 adapter so I could terminate the coax in a PL259 connector.
The problem is that the braid in this coax (and all of the other 75 ohm cable I have) is made of steel wire, and cannot be soldered. It is the connection between the braid and the PL259 that is causing the problem. Right now the braid is a press fit between the adapter and the PL259, and after a while the connection becomes intermittent. Anyone have any ideas how to make this a more permanent connection? Thanks & 73s.
