I have a VHF/UHF antenna (ANLI A-100) and was checking on it with my antenna analyzer (N1201SA) through 50ft of Mini-RG8x feed line. (Antenna is in attic area 30 feet up from ground)

I was expecting the standard curve showing an optimal SWR in the VHF and UHF bands. I did get this for the VHF band but the UHF, while under a SWR of 2, produce a rippling pattern across the band. I am new to antennas so I thought Id ask here from the most knowledgeable so...

What can be inferred from analyzer scan showing multiple minimum SWR (ripple) across a band?
