Thanks, Bill! It appears that the Rayzar Air does work well, but there's no compelling reason to replace a properly working Sensar. Something to keep in mind if a future replacement is needed. It does bother me that the VHF-low band has been ignored though. I had the same problem recently when shopping for an OTA antenna for my cottage. The ones readily available locally in a size that would work well, did not include the VHF-low frequencies, even though a popular local station broadcasts on RF channel 6. I bought one of them anyway, but then I stacked a dual element FM radio antenna with it to add on the needed channel 6 coverage. Hard to do that on an RV though. :)
