There are two satellite TV services available in Canada, Bell  and Shaw Direct (Rogers).  Bell dishes are smallest (18") and because their technology is the same as USA, simple roof mounted dishes are available for RV's. But  as of Feb 2024 neither one works in USA. Both services still work in Canada.

The manual rooftop dishes available from RV dealers will work  on Bell in Canada without modification.

The Shaw Direct dish is larger and elliptical, and only motorized automatic roof mounts are available commercially for RV's.  Manual dishes will  only work on Shaw  (Rogers)  in Canada with modification.
I provide details on how to build your own manual rooftop Shaw Direct dish in a later pararaph.

As part of the Shaw Direct equipment upgrade, a new satellite G1 has been placed in orbit at 107.3W. It has an antenna pattern which cannot be seen by users in the USA. All channels are now on this single satellite, which now makes aiming easier.

 t should be noted that a stronger signal is need to receive MPEG-4, and the smaller 60E dish may not be adquate for US signal reception. The larger 75E mobile dish is recommended. Still, signal loss due to rainout or dish movement will be more common and last longer.

VE3LGS EASY METHOD  for aiming dish with GARMIN GPS

I recently purchased a small handheld Garmin Nuvi GPS. This has main highways down to backwoods road maps built in for most of North America. Really handy in unfamiliar towns. You can drive straight to a laundromat in Arizona or a Beer store in Ontario.  By the way, if you are a real boondocker, you will soon find out that the GPS application for your Iphone or Android won't work unless you have a good Cell signal.  This happens all too often.

 
Anyway, I digress.

What is really helpful for satellite aiming, is its built-in ability to calculate great circle distance and bearing to any point on earth. As far as I can tell, this function is only available with a Garmin GPS.

Enter the location of your satellite into your GPS favourites list. In the case of the Shaw Direct primary satellite it is 0.0 deg N, 107.3 deg W. Name it and save. Now set your System/Settings/Units to kilometers. Every time you require the aiming information for this satellite go to your favourites list, page down to that satellite. Write down the distance from your location in km. and bearing given.
Divide the distance by 100 and subtract from 88. This is the elevation angle. Easy.

If you want the direction of the satellite set tools/navigation to "OFF ROAD" and the magenta line is the bearing.

EXAMPLE CALCULATION
In my case, from home, this is 5772km@SW. Subtract 57.72 from 88 gives 30.28. Set your dish elevation to aprox 30 deg and point South West. If your mounting post is vertical, rotate to peak signal and you will be watching TV.

* Simple Dish Tripod
In forested campgrounds, we look for shade and this means we must use a tripod mounted dish, to clear trees. For a lightweight Tripod use a cheap plastic camera tripod. Remove the Camera head, and replace with a 1 1/4 inch ABS PIPE hose clamped to the center column. I glued a bubble level to the top of the ABS pipe and this gives me one less item to find, and setup is easier.. Adjust level bubble by adjusting leg length on tripod.

* I have two cables, 30 ft and 50 ft. Only once in North Maine woods did I need more to clear the trees and had to move to a different camp.

* Use RG59 Coax if you are going to be moving often, RG6 if more permanent. RG59 will eventually pick up water and develop more losses than RG6. You can tell this is happening when the higher numbered transponders start losing signal strength. New coax should fix it or buy one of those inline satellite preamps from Radio Shack. Remember, it must be inserted out at the antenna to do any good.

* Change the dish elevation nuts to wing-nuts, or those black threaded knobs at Tractor Supply to make elevation adjustment easier.

* Keep the pipe clamp slightly slack to allow slip fitting the dish onto the mount. They do not really need to be tightened for camping setups when travelling with only short stops.

* On the side of your dish mount is an engraved scale for elevation setting. The standard Expressvu dish uses a line forward of the adjust bolt as a setting point, while the Shaw Direct dish uses the bolt center line. Check your manual.

* I also do not install the LNBF head bolt so I can store the LNBF separately. Just have a short 3' coax attached to the LNBF which I slip into the arm.

* The 3'junction provides a place to connect a Satfinder meter (available from Radio Shack). This Satfinder is a must have, to save setup time.

* Remove the Satfinder after setup to give you 5-8 more Strength units.

* I use slip on connectors at the meter joint to make connections even faster.

* It is also possible to drill out one of the spot welds on opposite sides of the LNB arm and insert a bolt, to make a folding arm. I used the lower one so that the dish and arm lay flat, face down, stretched out, when stored. Use the upper one if you want to fold the arm against the dish. The remaining pair of spot welds are then used as detents, or insert a cotter pin to hold the folding arm in the correct position when set up to receive. It works well.

With the elliptical dish the arm is removed simply with one bolt and can then be stored flat.

* I use three plastic topped "nail like" tent pegs from Canadian Tire to spike the tripod to the ground and keep the dish from toppling over in the wind. Hook them over or drill holes in the the leg braces and hammer into the ground. Use Rocks in places with no soil like North Maine or Newfoundland. Screw anchors only work in some soil, and the bungee cords usually supplied are too stretchy in high winds.

* If you are having problems with tree branch or other interference, try sighting the beam. Look out along either side of the dish arm, sighting a line from the bottom of the dish to the top of label on the LNBF arm (up 1-2"). This gives a very good approximation of the view which is slightly offset upwards from what appears to be the dish centre. Sighting will make it easier to know where to move to miss a tree branch. We often use this trick to find that narrow hole in forest cover with the only view of the satellite. (Easier in South USA than Canada because of the higher angle.).

* If you want to try a temporary roof mount, use a piece of 1 1/4" ABS pipe and hose clamp it to your ladder so that it stands vertical when you are level. Pop the dish onto this pipe when parked ( preset at the correct elevation angle) and rotate to peak the signal. Lock in place securely because your wind exposure is much higher at rooftop.

* All Shaw Direct receivers will  work directly on 12 volt, even the PVR.  Remove the provided power block and buy a 12 volt cable with the correct adaptor. These are available from anazon or Radio Shack in the USA.

HOW TO BUILD A MANUAL ROOFTOP Shaw Direct DISH

The Shaw Direct dishes in general are larger and need much more alignment because the signals are linearly polarized. This also makes the use of RV rooftop mounted antennas, difficult because as you travel west the skew has to be changed manually to match the viewed polarity of the satellite antnnas. But I have mine working in case you want to try. I bought an Antenna-Tek RV Manual Dish and removed the supplied 18 inch dish and arm for Bell TV.
In it's place, I mounted a 24 inch round Star- Choice dish. Two bolt holes almost line up, just needing slight hole elongation of the bracket. For the other two, new holes must be drilled in the dish.
Using the arm from the Shaw Direct dish I cut off 1 3/4 inches, Drilled a pivot hole and mounted the LNB. To set the correct arm angle of 75 degrees to the dish I attached two wire-rope 3/16 inch bulldogs around the stop bolt. Rotating the stop bolt rotates the bulldogs which act like a cam to set the angle. Make a template of the Dish and arm before you dismantle the existing dish and use it to set the angle on the new installation.
You may have to try a few Shaw Direct dealers to find an old working dish. They usually scrap them, but some still have a junk pile of dishes replaced by the newer dual satellite elliptical dishes. 

I have modified a standard Shaw  dual X-Ku LNB  for use with a round dish by glueing a second offset bracket to the LNB at an angle of 15* deg (skew for Ontario) and centered on Section "A" of the LNB. This will to shift the aim of the  "A" LNB to hit the centre of the dish. See the Photo.   

Good luck and let me know of your success.

I have used my Manual rooftop installation for 20 years across Canada, Alaska, and Southern Florida. In Inuvik, NWT, we watched the latest "Ice Road Truckers" while all US systems, and Expressvu would not work..

The elliptical dish is tricky to aim, and if you can get an older round dish, it has more gain and is much easier to hit one satellite.

If all this is too much, try this site which sells a Shaw Direct - automatic mobile antenna
OR
Motosat HD-SC2 for Star Choice
OR
Use a tripod and learn how to point manually.

I again suggest purchasing a tuning meter to give you an idea of when you are close.

Another Satellite service which makes your day in the outback with your motorhome a lot more pleasant is Mobile Satellite Radio
With this system you won't be always tuning for your choice of radio station as you cross the country. Have a look next time you are in Best Buy  $100-200 for equipment and $10-$12 per month for service.
I like the idea of FM output so that the existing vehicle radios can be used to listen without mods. It also means you can have the RV parked in the driveway and listen on the house radio.

Both Sirius and XM now broadcast to Canadians
While XM has sold more sets, it is my opinion that the Sirius system which uses satellites in elliptical orbits may offer better service for Rvers in more places than XM. With XM you need to be able to see the satellite "hot spot" to the south over the equator from your location and this will always be more difficult than receiving any one of the several Sirius satellites moving directly overhead. XM does not work well in the north while Sirius has good coverage to Whitehorse. but signals are lost for a few hours a day as you travel north to Alaska. I have had a lot of feedback on this problem and most users complain of signal dropouts from tree or building interference when deep into Canada. XM may be workable only if carefully parked in Newfoundland or Yukon so they are going to have lots of technical problems. My best bet for complete mobile coverage would be Sirius. Good in Newfoundland, and most of the day 
in Yukon/NWT/Alaska. XM gets hard to get in Northern Quebec at James Bay, but is useable when parked. It is a good thing the trees are short there.
