correct. in the old analog days you'd get progressively more static or double images the farther away the receiver was from the transmitter or if there was something between the receiving TV set and the transmitter. with digital it's an all or nothing proposition. if bits are dropped then the receiver will not be able to decode the signal and you'll see a pattern of pretty colored squares on the set (some call this 'pixilization').

what can be really frustrating is if we're camped by an airport or train tracks and a train passes by or a plane takes off/lands the signal may momentarily 'pixilate'. that's another reason why the antenna should be as high off the ground as possible.

our new MH has a Jack amplified antenna at a fixed height on the roof. it works great when we're in an urban area., not so much when we're not. we wanted to remove that and replace with a Winegard Sensar IV/Wingman combo but the holes required for the Winegard was smaller leaving us a gaping hole on the roof (which could be sealed) but the gaping hole on the ceiling was not something we wanted. we're able to get whatever locals there are in a particular on our DISH receiver.

Hands down, the BEST OTA antenna for RV service is the Batwing/ Wingman combo either with the add-on Wingman or the newer Sensar-V Batwing antenna.

- Any Omni is complete junk period.
- The Jack is a terrible performer on UHF and worse on VHF. The move back to VHF will likely obsolete this antenna anyway.
- I haven't tested the Razar yet, but simply by design, IF you are going for maximum gain, its not going to equal the Batwing.
