With the test, I found out just a slight bit of tilt helped increase the signal of channel 2/Real 39 by 10%, but a decrease in the signal of channel 5/Real 27 by 3%.

I also noticed a similar scenario when I tested the C490 with the radio shack amplifier, the antenna seems that it becomes more directional, or so it seems. On channel 11/Real 10, I saw a 20% increase, and on channel 8/Real 8, I saw a 20% decrease.

So I guess that when I finally install the antenna on the roof and all is set up, I'll do a final test on the roof with tilting and the amplifier.

I noticed there is a beginning of a propagation opening, so I'll test the tilt again once that closes.
