Not with a preamp, assuming you installed it at the antenna, the splitter makes no difference at all in SNR. My system has an 8 way splitter, 13.2 dB insertion loss...
A splitter that points signal to 2 TV's have around 3.5db of loss per port in signal strength. Not a clue what you are referencing. Before installing the preamp that signal loss was a make or break reception point.Not with a preamp, assuming you installed it at the antenna, the splitter makes no difference at all in SNR.
And you can also have a higher Signal Strength and low SNR like one low power station I'm getting. 59/60% but it's SNR is 16... half the time it's in and out. RF 34 was solid at 40% and 19/20 SNR mostly but once you get to these lower numbers, any little thing will cause you to lose reception. The goal is to have reception reliably. Both measurements are indeed, important.Signal strength and SNR, signal to noise ratio, are two different things. With digital you can have low signal strength, but if the SNR is at a certain level your TV you will have a perfect picture and audio regardless of the splitter.
Wow, if I had your setup instead of my knockoff antenna at 18ft, I might get something at 200 milesWell I get Buffalo stations 80 miles away consistenly. However, they are transmitting from 1800 foot mountain tops with 1000kw erp. Yet low power station serving the Buffalo markets 50 miles away I do not receive.
All I have is a CM 4221 about 35 ft on the roof pointed at the general Buffalo area.
Tropo and other anomolies can happen at any time of day especially in the summer months. Many mornings I get Rochester for about an hour or so and them its gone. Thats 100 miles away. Also often in the late evenings they re-appear.
Any kind of antenna testing this time of year is at the mercy of propogation due to unstable temp variations.
Like this:Try a fence post from Home Depot. If I recall correctly, a top rail is close to 1.25" and about 12 feet long. I used one with a chimney mount for awhile.
