Well, I tried hooking up the CM 3041DSB this afternoon....and she didn't give me anything to write home about. Didn't improve my signal at all. On the contrary, like Pabuwal's experience, it made 'em worse!
While I was up there I tried "Tweaking" my direction a bit to see if that improved anything. A twist here and a nudge there didn't get me anything extra picture wise, but I had the wife on the other end of the cell phone watching the meter on each Philly digital local so I knew where a good spot would be.
Maybe someone can offer a thought on just WHAT my problem(S) is/are. I even added another 5 feet of mast on to see if that improved my signals...no luck. The strengths I had WITHOUT the 5 foot mast were the same when I DID put the 5 foot mast on (bringing the antenna height to around 9-10 feet above roof level (I have a ranch style home)
KYW was rock solid no matter how much tweaking I did---unless I turned it 20-30 degrees in either direction then I went from 100-0.
UPN (57.1) was the same thing. Rock solid. Steady.
WCAU is dead as a door nail!
WPVI---with tweaking I got the strength level to go from a 9 to a 27. But that was it. Not lockable though. Again, even WITH the 5 foot of masting it was still a 27. Yet, this is the same channel that a few nights ago I had a STEADY 56 or so on and was able to watch. Same thing happened Thursday night I believe. Haven't tried it yet this pm yet.
WTXF bumped to a 24 with some tweaking. Still no steady lock though. Same thing when I had it on the mast
WB out of Philly (not sure of call sign---17.1) was only able to hop up to about 20 with some tweaking. No lock.
I also swung the 4228 around towards NY and picked up WCBS at 100 strength. Solid. Big time. Also picked up WNYW (Fox) at about 50 or so. Steady lock. ABC/NBC were dead, 0 on the meter. WB was at a 2 or so. UPN at a 5 to 10.
So, that's where I"m at. I'm going to order the CM 7775, since it seems to be for UHF, has a low DB noise ratio, has a 75 ohm connection...AND Paul hooked one up on his own 4228 and had positive results.
I keep telling myself...trial and error, trial and error.
I had posted a thread earlier today under CM 4228 heading just to find out basically HOW that thing/bowtie/UHF antennas work. That's where I'm at now. I've read up on how digital signals travel and UHF signals as well. But, I'm at the point now where I'm getting consummed by the need to figure out HOW to get the locals I'm able to get (within reason). That and the fact that the little lady is KILLING me over the fact that I can't get NBC from either direction
