I installed the same antenna from Walmart as the video demo shows. It took me maybe 15 minutes. Once the threaded pieces were together and installed, I pushed the boot over the end of the antenna (no drilling or cutting needed-it is rubber) and left just enough room to screw the antenna in place. Then it was pushing the boot the rest of the way down and inserting in place. A small flathead screwdriver, used carefully, helped get it in place. Wish my other projects went so smooth. It had great reception in the garage. On the road?? Time will tell.
