Do You Need Insulators On Your Antennas?

I’ve been away for a couple weeks. I went camping with my son during the great HF radio blackout of 2024. Fortunately, I survived. We were in an area with zero cell service, no repeaters, and no FM radio reception. Add in no HF radio either, and it turned out to be a pretty quiet weekend.

Last weekend I took Core-Vision 2 dayStructure Assessment class. It’s the 2nd time I’ve taken it. All I can say is I’m not very good at that stuff but I keep trying.

Anyway I did some testing of a common radio procedure when it comes to HF antennas to see if it holds water.

Do we really need to use insulators at the end of our antennas? Watch the video below and see the results.
