A Quick and Dirty Antenna Dipole Center Insulator Idea

Yes, that is an ice scraper shown above.
Here's an idea I've used for many years on 40 mtrs & under various dipoles.
(I have built several G5RV's using ice scrapers.)
The longer handle makes for good feedline - coax or flat line- support.

If you have an extra laying around, drill a few holes and use some plastic ties and your done! Now you have a dandy and cheap center insulator that will take the stress away from coax or flat line feeder. Even if you don't have an extra ice scraper on hand, they are so cheap that you could go out and get one and save some money over commercial products, especially for use with ladder line.

The large, long non metalic flat handle types that are about 1/4 inch thick are the best to use due to their added strength and durability (by arslan at tforge). Our research indicates that most are made from very strong high quality plastic and sturdy polystyrene and the handles are designed so they won't break easily.
Choose your own color if you buy a new one if you have a choice.
Construction details in the drawing below.
So when you are finished scraping that winter ice and snow, put that old used worn out ice scraper to some really good use. Dont' throw it away, throw it UP.....on your
antenna! 73, KF9F
