There is one thing I will mention. I DO NOT KNOW IF THIS WILL BE A PROBLEM (Disclaimer required) but if it is I mention it because.. Well, there are two solutions.
The winegard switch is not just a switch, Depeding on the model it is 2 or 3 things.
1 Switch (you can see that clearly)
2: 12 volt power supply for the mast head amplifier built into the antenna, This is very important and IS the problem I mention.
3: Optional (And there is a solution here too) RF Modulator for use with DVD player on TV-2,3, and so on.
Now, if the new switch does not put 12 volts on the antenna coax the ampifier in the rooftop antenna will not work, in fact it will attunate the signal instead. This is not (normally) good. So how do we fix it. (Two or 3 ways)
First: Winegard makes a device which I call a power inserter, not sure what they call it, it looks a bit like a signal splitter, about the size of an ice cube, but instead of 3 Coax connectors it has two of them (one marked ANT) and 12 volt leads. Just put it between your switch (ANT connector towards the antenna) and feed it 12 volts.
Second and third is the Sensar Pro device, very handy for aiming the antenna it is a variable amplifier as well (A 2nd pre-amp) and really does improve reception, not as much as I'd like but it works. (IT took me from zero to one solid sataion where I'm parked and .. Well, That's good enough to make me very happy).
Like the inserter, you put it between the Antenna and the switch... OPTIONAL...
If your TV has seperated ATSC and other inputs, or if like my you are using digital ATSC to Analog NTSC converters.. I ran the extra coaxes, the Sensar Pro's two outputs go direct to the converters, which then feed Digital Video Recorders on line-1 IN.
When I'm in a park with free cable,, that goes to the DVR's on "RF in" (Antenna connection) so they will choose input per their program, Lets me record Tier 1 stations off cable, Tier 2 (Which are not often on cable) off the air. Tier 2 often has the best program (What is tier 1 and tier 2,, The tier is the number after the dash, as in 7-1 or 7-2, which are tier 1 and 2 respectively) .
I'm very happy with this lashup. but then I should be, I designed it to make me happy
