Yo M+13: Yes its a great post with great info, I'll bet many a distinguished radio enthusiasts have written down your Penetrator SPT-500 lengths. I did! I know there were quit a few guys out there that had SWR problems with the new Hy-Gain SPT-Penetrator 500 Antenna.

My advice was to use the older assembly instructions, but if the bottom element Aluminum Tubing 1 1/4 inch diameter wasn't long enough you couldn't make the proper length ( 71 inches ) The new SPT-Penetrator 500 instructions has the antenna too short for CB use, and they do not call out the bottom vertical 1 1/4 inch diameter tubing length.

Again the use of a Antenna Analyzer will enable you to see were the antenna has the lowest SWR and allow the user to adjust it to were the distinguished radio enthusiast wants it to be. Yeah Ten-4.

Good going....
