I built a "J" pole out of 300 ohm inlead wire and have it trimmed where at
147.210 I have a SWR of 1.6 and on the low end at around 145.390 I have 1.2.

To protect it, I put in a 1" PVC pipe and now the SWR is way off the scale.
Is it a bad idea to encase it in PVC or can I trim it down to get a better
reading?


Assuming your PVC is non-conducting, it may be changing the
velocity factor. Trimming would be the way to go.
