If we were discussing an outdoor installation I would accept the "dicey", "Ok", VHF performance of the 4228. In the attic, extra antenna performance is prudent.
While Channel Master's
ad copy does claim H-VHF capability, I find it troublesome that their
catalog performance data (PP-10) indicates the Average Gain is "N/A".
In the end, If the 4228 can be had for $82 shipped and it works by itself, great.

On the other hand, the DB4e is $53 shipped and the Y5713 is $27 shipped.
