[TVARC] Flagpole

Mon Apr 24 11:24:26 EDT 2023

One thing that you might want to look at before you reinstall it.  In the pictures it looks like it might have cracked at the edge of the aluminum tube.  If the tube has a sharp edge or burr on the inside it might cause a stress riser to cause the break.  i’m not 100% sure but it should be looked at.

In my case it broke right at that gap between the aluminum parts of the pole, and I was flying a flag!

I was not flying a flag at the time. The gap was about 2 in. Here are pictures of the break.

Hi Larry -

Very sorry to hear about your flagpole. As one who also has a similar antenna, a couple of quick questions: Were you flying a flag at the time and was the break in the space between the two flagpole parts? Oh, and how large was the gap between the two parts before its, as Spacex would say, rapid unscheduled disassembly.?

Thanks, and 73,
Paul, KM4PIH

John, If you remember I was the first person to build your antenna before you published. I used your exact part from Interstate Plastics. I am sure we didn't both have the same batch. Mine was a perfectly clean break.

Larry, Greg,

I have never heard of such a thing  happening. I would like to see the
broken piece.

The material that I used goes under
the commercial trade name of "Delrin."
It was manufactured by Interstate
Plastics and the invoice description
simply says "natural acetal rod."

The article was published in the
September 2017 issue of QST
and I have gotten feedback from
folks all over the country. I have
never heard of the rod breaking.

I have heard of the pole snapping
ABOVE the rod, but I have never
heard of a single case of the rod
itself, snapping.

I am thinking you folks must have
gotten something else or they might
have had a bad batch, I don't know.
That is why I would like to see a
piece of what broke and a copy of
the invoice / packing list, if you might
happen to have kept it.

Could I get a piece from one of you?

Thanks & 73,
John, NP2B

FYI:

Did not think it was possible, but I came home this evening to a flagpole laying across my driveway. Upon further examination, the acetal rod inside the first five feet of the pole had snapped right off. It must have blown pretty hard here this afternoon in St. Charles to cause that to snap! Anyway, back to builder mode again! Not particularly happy I have to repair, but that is the life of an amateur radio operator!
