I can't explain why my model did not work with the specs that JAF0 and the Vortex Website published, but here is a scaled model using the dimensions I received. I set the model at 27.205 and used the dimensions I got for 27.185. I also used direct feed, just like the Website shows. I set the model at 36' feet to the feed point over Average Earth as a ground description.

When I scanned the model I found it resonant at 23.200 MHz. My model showed a very wide bandwidth of 3.90 MHz but not 4.37 MHz as reported. I scanned the model ordering the software to scale the dimensions to my CB frequency. Below are my results

The patterns look similar and the bandwidth, match, and angle are very good, but the model does not show the gain reported and the elements dimensions are much smaller than suggested.

1. The model over Real Earth.
2. The model in Free Space showing the Average Gain results.

I see the Vortex pattern did not copy well...so here is the video from Vortex with their antenna images.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
