ROADKILL
Why is this page called Roadkill? Because it is just that, namely more Roadkill along the information highway.
I am not sure what the aim of this page is going to be, but so far it is just a collection of information related to RV Travel. And also it provides a peek into our other life, which some of you may know is on the road. Living on board our Trawler "Tumblehome" in the summers, and in our motorhome "Harvey" in the winters has been our life of choice for many years. The Dos stuff is just something I did to make internet access easier and faster on the road. The autopatch was built so I could reachout from the boat, many years ago, and since it is still working well, we keep it on the air from a corner of my shack at home, for others to use as well.

As I think of something I will add it. Check back again.


How to use Expressvu or Star Choice in USA
The above is a package containing a program to calculate your own antenna setup angles , knowing your location coordinates.. (from GPS or even Wallmart maps) I also included Elevations, and Azimuth for selected cities in a file that can be emailed to your pocketmail device.
* Reports are that the 18 inch dishes are being sucessfully used in some fringe areas, where the graphic shows 24 or even 30 inch. It just means that setup is trickier and you might be more succeptable to rain fade. See the notes below on South. Signal strengths drop off dramatically in fringe areas, but some channels will still be received. This just reduces your selection.
USA Dish Aiming
While some of the information here is specific to Canadians, US RV users might find it useful as well. The computer program will allow you to find any of the Echostar Satellites in Canada as well as the Canadian Satellites in USA.

And here is a link to a similar helpful site with more ideas, specifically for USA users.

Simple Dish Tripod
RV rooftop mounted dishes are even smaller than 18 inch. They may run into signal problems in South USA or Mexico, and reportedly need more maintainance as they jam frequently. This means buying a 24 or 30 inch dish and mounting separately. In forested campgrounds, we look for shade and this means we must also use a remote mounted dish, to clear trees.

For a lightweight Tripod I used to 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.

When that tripod got tired (plastic got brittle from sunlight) I found an old tripod support for camera lighting. It was steel and by shortening the centre pole I could fasten my ABS pipe from the old plastic tripod. All is still well, two years later. Another friend saw my arrangement and cut down a small projector screen base to accomplish the same idea.

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, but is cheaper, easier to find and easier to work with. You can tell you are getting higher cable losses 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.

Other Hints
* Change the dish elevation nuts to wing-nuts to make elevation adjustment easier.

* Keep the Pipe clamp slightly slack to allow slip fitting the head onto the Base. They do not really need to be tightened for camping setups when travelling with only short stops. But you then must be sure to allow extra elevation to compensate for the sag due to the offset weight of the dish . This is a fixed standard and is added directly to the calculated elevations. The standard house dish uses a line forward of the adjust bolt as a setting point, while the larger dishes use the bolt center line. Check your manual.

* I sometimes 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 and a marriage. If you do not understand when you first read this, you soon will.

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

* I use slip on connectors at both the meter joint and at the RV through wall plate 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. I tried using remaining pair of spot welds as detents to hold the folding arm in the correct position when set up to receive. Eventually I drilled out this second detent and made a pin on a string to hold it in place. Either way works well.

* I use three plastic topped nail-like tent pegs from Canadian Tire to stake the tripod to the ground and keep the dish from toppling over in the wind. Hook them over or drill through 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. Kneel down and sight along either side of the dish arm, sighting a line from the bottom of the dish to the bottom of the LNBF (up 2-3"). This gives a very good approximation of the view which is 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 RV 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.

* Don't plug into a phone line if you aren't at home. Big brother Bell is watching you. I found Star Choice to be more RV friendly.


Dish Aiming suggestions for Canadians in South USA

*NEW INFORMATION

Expressvu has been given a used Dish satellite so that it can reorient antennas and now many channels are no longer available south of a line from Oregon to Atlanta. If you were counting on taking your expressvu south this year (2005) forget it. Better cancel and try Star Choice.

The following instructions are for receiving the remaining transponders which can be seen in south USA

Those dead in south USA are reported to be transponders 1.2,5.6,13,14,15 ,16,19,20, 27,28,29,30,31,32.

* I had received reports of 80% plus signal strength on Expressvu in Brownsville, Texas and Yuma, Arizona with the standard 18 inch dish. It is very, very fine tuning. Two degrees will loose signal completely. Make the mounting post vertical to simplify alignment. It is suggested that first, you rough set elevation a degree or two high. Then peak azimuth, followed by returning to peak elevation for best results. It seems Echostar wants to intrude, and it is easier to "sneak up on it " with a slightly higher than recommended elevation and then fine tune.

* There is also a substantially better signal here with transponder 01 than 31 or others. And ODD transponders are much stronger than EVEN. If you cannot find the correct satellite, try manually setting on transponder 01 and trying again. And with tuning so fine, you may find it more necessary to clamp the dish when completed to avoid movement in the wind.


What about Echostar Interference
The lineup of satellites over the equator is not a straight line, as seen from a point on the earth. From your location they are all located on an arc that starts at an easterly horizon, rises to a maximum elevation due south of your location, then down to the westerly horizon.

The main Expressvu satellite is located over the equator, at 91 deg W. This is roughly south of a line between the west end of Lake Superior and Louisiana (Mississippi River).

There is another Expressvu satellite at 82W with mostly HDTV and not of much interest, but it is occasinally locked onto when setting up in a new location. Just swing slightly west and try again.

If you have accidentally locked and peaked onto Echostar US satellite, then set elevation about 8 degrees higher (in the east). Then look slightly to the left for another peak ( weaker than Echostar). In east Texas, the elevations of the two are almost equal. If you lock on Echostar here and really want Expressvu, turn up the sensitivity on the sat finder and shift left. And in the west where Echostar 110 is the higher, decrease your elevation angle, say 8 degreees, turn up the sensitivity, then shift left.

Echostar has a much stronger signal, uses the same frequencies and is also circularly polarized. It is extreemly easy to lock on it in error. Expressvu users can actually watch Echostar channel 200 (the welcome channel), but nothing else, as you do not have a contract with them.

Best way to not lock on Echostar is to PRESET ELEVATION (tilt) just above the calculated Elevation. Then you will not have a problem hitting Echostar by mistake. If elevation is correct, you will only hit Nimiq as you swing the antenna.

We use a small inverter to feed only the Satellite Box from 12 volt. Ours takes 1.85 amps from the 12 volt system. Unplug the inverter to turn satellite off, because the dish still draws 1.85 amp when it is turned off with the remote.


Other Problems
One Bounder seen in Arizona has his roof mounted dish down on one side of the centre line of his sloped rubber roof. This means it is mounted tilted sideways and any rotation of the dish also changes elevation. It is driving the owner crazy trying to set up at each new site. I do not know if this is a dealer or a manufacturer screw up. But if you have choice, make sure yours is mounted on the centre line of your curved roof. Or buy a tripod.

We have had reports of the signals being marginal in the Northern Bahamas on the even transponders using 18 inch dishes. Same report in Baja. This means that some programming is not available for part of the day ( eg Discovery and Radio Two) We are awaiting a report on the use of larger dishes to be tried at several locations.


Star Choice
Much more difficult to tune and needs a third parameter to properly orient the antenna. I have talked to one Star Choice user from Ontario parked near Okechobee in Florida. Met another in Tuscon last year. He had it working and his explanation was the new satellite is much stronger and now is useable down to southern Mexico.
I myself have no experience with Star Choice but anything would be nicer than having to deal with Expressvu.
Note, 2004-2005: I am now switching to Star Choice. From my preliminary tests the receiver takes only 0.95 amps compared with 1.85 for Expressvu. This is a big bonus for solar powered systems, such as ours. As well, the Star Choice picture is much clearer, as Expressvu was getting noticeably fuzzier as they added extra channels. Star Choice won't cut you off as a legitimate Canadian customer who occasionally mobiles into USA.
IF YOU ARE GOING TO MEXICO or SOUTH USA ONLY STAR CHOICE WORKS>
The Star Choice 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, almost impossible. Do not think about Star Choice unless you are going to park for extended periods and must have Canadian television.

The elliptical dish is tricky to tune, and if you can get an older round dish, it would have more gain and be much easier to store. With the elliptical dish the arm is removed simply with one bolt and can then be stored flat. There is no sense in wasting time trying to mount the star choice lnb on a rooftop dish designed for a DISH network type satellite. It won't work unless you can figure a way to reorient the arm to match the skew angle as well. I can't. Use a tripod and learn how to point manually.
(by the way, the satellite is located south of Tuscon, so the skew is almost zero in Arizona and it might just work there, Yuma or Quartzsite. Let me know.)

I again suggest purchasing a tuning meter to give you an idea of when you are close. The problem with sighting the satellite with Star Choice is the location of the two satellites straddles the much stronger Echostar satellite at 110 deg W. The primary Star Choice satellite is at 107.3W and the secondary is at 111.1W. The primary carries all the channels in the basic package and is the one you are interested in. When aligning use "options 6-3-1" for the tuning meter and "options 6-0-5-Screen C" will show the signal to noise ratio.

Mobile Satellite Internet
There has been a lot of recent interest in how to have an interconnct to the internet from the middle of the Arizona desert or in the backwoods of Ontario.
Have a look at
DATASTORM - Mobile Satellite Internet and if $6000 equipment cost plus installation on top of your RV is acceptable, then $100 a month for service should not be a problem. This unit has an especially made RV roof mount bracket which even fits on an Airstream.
Mobile Satellite Radio for Music/News/Sports
Another Satellite service which makes your day in the outback with your motorhome a lot more pleasant is
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 or Circuit City. $200-$300 for equipment and $10 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.


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" over the equator from your location and this is always more difficult than seeing one of several satellites moving directly overhead. I have not tried either system so this is just a feeling, and not from actual experience.
