Winegard vs. Jack antenna (again)
This is my second attempt to do a Winegard vs. Jack antenna comparison. Here's my test setup: Antennas: Winegard Sensar III with Wingman attachment and King Controls Jack antenna head unit. T...

Hi Tom:
It looks like you have so far just used the S.D. tuner you purchased to locate and scan for the RF channels. All the channels found are not very far from your location (only up to 45 miles).
I am not familiar with the tuner used. Since you are most likely there for a while have you connected your television to the cable and scanned for the channels? I would use the TV's strength meter to zero in the signal by moving the antenna. Then record the reading. Do this for each channel.
Then do the same for the other antenna.
Are both antennas getting all of the same stations? How do your television's strength readings compare when comparing the number's?
At the moment you have nothing to verify readings taken from the tuner and your computer.
Since the television stations output from their transmitters may vary considerably from each other the numbers don't say much yet.
It's possible the dB numbers recorded from the first and second run came from slightly better or worse connections.
If the trend you think you are seeing is correct the strength readings taken from your television set should trend the same. By the way the television set is "real world" for sound and picture received. Also for it's strength meter for the signals actually reaching the set.
I am not knocking any of your numbers yet. Just waiting for additional testing.
