No problem: There is no one antenna that will get both the Mt.Royal stations AND the Mt. Mansfield, VT stations without using a rotator. Using a rotator is not much of an issue for one TV set, but using 2 TVs can be a bit of a hassle when you want to watch different programs from different cities at the same time.
The Vermont stations are already all-digital, and you do have some digital stations in Montreal, but most of them will go digital by August 31, 2011.
In any case, you will eventually need a digital converter box for the non-digital TV set that you own. I would recommend using a box that has an analog pass-through connector that will let you use the built-in analog TV tuner in the older set to watch the existing Montreal analog stations.
if this was my installation, and I was limiting my installation to 2 TV sets, here is how I would proceed:
Mount 2 antenna on your roof: a small all-channel antenna aimed at the Mt. Royal transmitters in Montreal. I would use a Winegard HD-7080P or an Antennacraft HD-850 aimed at 325 degrees by your compass for this purpose. You will need a bit larger antenna to see the Vermont stations, and an AntennaCraft HBU-44 or a Winegard HD-7696P will do the job for you if you aim it at the Mt. Mansfield transmitters (150 degrees by your compass)
Here's where it gets a bit confusing: we want to run cables from BOTH antennas to separate 2-way splitters centrally mounted where they can be easily connected to cables that will run to each TV set. We will split each signal 2 ways, then run one cable from each splitter to both TV sets, so that both TV sets will be seeing a signal from each antenna.
We then use a coaxial cable A/B switch at each TV set to take the two cables coming from the antennas, connect the two cables to the inputs of the A/B switch, and run ONE cable out of the A/B switch to the antenna connector of each TV tuner. You will then select which city you want to watch by selecting the antenna by using the A/B to connect the TV tuner to the correct antenna: one selection for Montreal, the other from Vermont. A/B switches are available from a number of sources, such as The Source in Canada:
