SlimJim 2 Meter Antenna

As the title states, this is the slimjim 2 meter antenna that I just completed. The antenna was made with quarter inch copper tubing, or refridgerator tubing as they say. The base section is a inch inner diameter PVC pipe section. The slimjim boasts more efficiency over the standard 5/8 wave antenna because it's lobes branch out horizontally, rather than at a 15 to 35 degree angle. This means, theoretically, that more of the gain is radiating omnidirectionally at your targets, rather than getting lost in the sky. The antenna is fed like an end-fed zep or j-pole and the matching section is contained inside the pvc. So far I have had very positive results with it.

Interesting article you got here. I'd like to read more about this matter. The only thing this blog misses is some pictures of any devices.
