I'm not familiar with this analyzer, but I suspected the 180 mhz might be the default bandwidth for its scan range.

If you limit the scan to a CB frequency, or a range in the CB band, and don't use the default, then I think you will see a much better curve without all that garbage. No antenna is going to report good with the scan set to a 180 mhz range...when the antenna at best might only effectively work a 1 to 3 mhz bandwidth. Why would you want to scan a CB antenna at a frequency for 2 or 80 meters? You ought to know such results would be off the charts and riddled with losses.

You need to talk to Bob how to set the scan range, and then I think you will see some results close to 27 mhz for a 102" - 108" whip.

Man, I may be the one that is all corn'fused, but what is in a 102" whip antenna to take apart and check?

Are you having a bad day?
