CDX, I misunderstood your question about the length of my Vector used to compare the GM. The length of my Vector was a little longer then the new Vector main radiator length. Around 28 feet. The difference was with my cone section. My cone was larger in diameter and shorter in length. If you read my initial reports, I thought this improved gain over the old stock Vector I had up for over a year with improved bandwidth into 10 meters.

Additional testing to many more stations I normally worked showed almost no difference in gain but it did have wider bandwidth. I've found testing at 50 miles can be hard even when changing the antenna out within 20 minuets. It almost requires an average signal check taken over time to the same station to spot the difference between propagation and antenna gain.

I think you can tell from my later posts about the larger loop on the Vector that I was somewhat disappointed as I got to use it more and recommended others not copy my modification. I feel shortening the radial length boasted 10 meter performance at the slight expense of 11 meter gain. That did take time to notice because at 50 miles an S-5 signal can easily drift an entire S-unit within seconds due to propagation!
