Does VERTICAL angle matter?
How weird is this...
Prior to my putting my Channel Master 4228 antenna on the mast, it was LYING DOWN on the roof. I went inside, happened to check the TV, and was happy to see that I got a bunch of channels already.
But then, once the antenna was vertical, I LOST SOME!! No amount of rotation, for the past 2 weeks, has gotten them back.
That meant that the antenna did better (for some ch's), lying on an averagely-sloped house roof, say 20 deg from straight up.
So, is it normal for the VERTICAL angle of an antenna to make a diff? Or just the rotated direction?
And most importantly, what can I do? Has anyone ever angled their antenna up a little bit? Maybe by using a piece of wood?
These are the ones that were 'catchable' when the antenna was lying down:
7-1 WKBW [it would be my first ABC]
29-1 Fox WUTV 29
29-2 Fox WUTV 29
29-3 Fox WUTV 29

The two-word reason for weird reception by a horizontally placed antenna is multipath interference. TomF.1 already gave you an excellent response in post #47 of the ON - East of Oshawa to Ottawa - OTA Results thread (yours is #45):
Also here's a post on antenna tilting from the OTA Installation Tips And Tricks thread:

My dual PR-8800 array works better tilted than non-tilted, when trying to bring in the very-distant PBS station from Norwood. I've not measured the angle, but it looks to be about 10 degrees upward from vertical.
