Sounds to me like your coax job has been working just fine for the last 17-18 years.

If you still have them, let me suggest that you terminate the coax run in a good 50 ohm load, send some RF in at the other end, and measure the loss as well as the SWR. If the coax has become contaminated to a significant extent then there will be loss, and to the extent that the lossy sections and the barrel connectors provide impedance bumps, the SWR may be other than 1.0. Do this on all bands on which you used the vertical. Repeat the experiment with the individual sections of coax, without using the barrel connectors.<br /><br />I see that the antenna is rated for use on all bands 80 m through 6 m. My guess is the barrel connecors aren't that bad, even on 6 m. I don't see whey they should be inherently lossy. If their characteristic impedance is other than 50 ohms then they will put a bump on the line but slight increases in SWR won't raise the loss that much. Now up on 2 m it's likely another story.<br /><br />If you run the experiments, let us know what you find.<br /><br />David Ryeburn VE7EZM and AF7BZDavid Ryeburn VE7EZM and AF7BZhttps://www.blogger.com/profile/10215002968835286422noreply@blogger.com
