I ordered (Solid Signal) and received one XG-91 and one CPA-19 pre-amp. Installed antenna (no pre-amp yet) and pointed to 329 deg. mag. - the direction of my stronger signals. Nothing. (Screen looks like bad snowstorm). Pointed to 120 deg. (splitting the difference between 112 and 127)-the direction of my weaker signals. Still nothing.
Install CPA-19 and point back to 329. Voila! Ch. 15, 16, and 34 with sub channels all quite strong. Point antenna at 120 and Voila! again. Ch. 19, 21, 27 and sub channels all quite strong (65-80%). The unexpected but very good thing is that I'm also getting the signals from 329 at 60-70% with the XG-91 pointed at 120. I don't understand why, but I'll take it. So it seems I won't be needing a second antenna/pre-amp and A/B switch after all. Thanks for the kind advice. Thought you'd like the feedback.
