Ed's reply seems completely reasonable to me. It is easy to do and you get a
good idea about anything that might require some attention.
And if you have an inexpensive VNA - you can run TDR function and
probably get some idea of where the problem is. You can certainly tell
if coax has been damaged mid run.

Subject: Re: [TowerTalk] 160m vertical and the number of radials
I find it way easier and much more straightforward to simply record the
specific X and R at the feedpoint when you install the antenna. Then make
it a habit of check that measurement once a year at the antenna feedpoint.
If the R is creeping up, then the radials need some work.
On the coax. Just disconnect the coax from the feed and do a loss
measurement from the station. Again, record and check annually.
