Quick End Insulator

Here’s another quick hack that took longer to write up than to actually build. I recently built a portable vertical antenna using some #26 Stealth Wire. I needed some sort of end insulator that would facilitate pruning the wire to resonance. Here’s my quick and dirty solution.

Using scissors, I cut a piece of plastic from a used up gift card I had in my wallet. The piece I cut is about 1 inch by 0.5 inches. Then, I drilled 3 holes in it. Two of the holes were just slightly larger than the #26 Stealth Wire (The Wireman Product #534). These holes hold the wire in place. I drilled a larger hole for attaching to a light line or, in my case, a small clip at the top of my telescopic pole. I also rounded off the corners a bit.

The end insulator and the gift card from which it was cut. (Disclaimer: I have no financial interest in the Wawa company, except that I have consumed untold quantities of their coffee over the years.)

So far, this is working out well for my portable vertical antenna. If I was using heavier gauge wire, I would definitely use something more substantial than the gift card. I also wouldn’t use it for a permanent installation. But for an ultralight antenna that is only used for portable excursions, it’s perfect.

If I ever need to replace it, I have enough of the original gift card left to make a bunch more!
