But on VHF the 40" has the edge and can "see" real channel 8, just over the "digital cliff," 16-17dB SNR. The Winegard does not pick up channel 8 at all. So, the RCA probably has more gain given its larger boom, especially for weak channels like 8.

weak signal might not be good with a splitter to feed 2 tvs but you could use a distribution amp .. even an 8 port that is very weak would just pass signal without much power boost if your signals are very high on some stations.. a 4 port could actually give you a decent boost in strength to get channels that are marginal.
Using a splitter or a distribution amp and a splitter might be a good simple solution, but I would want to see a TVFool report and know the exact address and exact coordinates of the antenna (by PM for security) before making a recommendation about improving the reception of channel 8.

My wild guess is that the Winegard 7000 doesn't have enough gain for 8. Adding more amplification doesn't compensate for a poor quality signal coming out of the antenna terminals. The signal will be stronger, but not better quality (SNR and errors); GIGO.
