Road
Many of us have become
used to clear, static-free television reception from the 75-channel,
cable system at home. RVers are often disappointed however when
we only get reception from a few local TV stations as we travel
to different areas in our motorhome. On some days, we have no
usable TV or radio reception at all since we are too far from
local stations or are parked somewhere in the mountains where
some roof mounted antennas cannot pick up transmissions from a
nearby city.
Some people have used satellite antennas on their
RVs for many years to solve the problem of TV reception. Do you
remember the old six-foot antenna from A&E that took up most of
the roof space on the RV?
My wife and I had been using cable at home for
many years and really didn’t want to lose any of our favourite
channels when we were on the road.
Enter KVH TracVision
When KVH asked RV Lifestyle magazine to test its satellite antenna
system, I decided to see what the small antenna could bring in
from the sky, to our home and on the road. Canada has had two
satellite TV systems up and running for several years now. Bell
ExpressVu and StarChoice claim to provide reception to anyone
in Canada.
A few years ago we tried the StarChoice system,
but now it operates from two different satellites so it requires
a larger elliptical dish with two LNB receivers pointed in different
directions.
We chose to use the ExpressVu service because
it was compatible with the KVH antenna and ExpressVu encourages
people to use their system both at home and at the cottage. The
only difference is that RVers have their cottage on a different
lake each weekend. Not only can we still get all our favourite
stations at home, we can also follow our local TV and 42 audio
channels wherever we travel. We simply had to get used to a new
set of channel numbers.
Wherever we are now, we can look at the weather
channel to find out what is going to happen in the area where
we plan to travel. We follow the movie network across the country,
and receive up to 300 channels of quality, digital programming,
with all our favourite networks, radio stations and CD quality
sound.
The L3 antenna that Jeff Carew at Apache Camping
Centre in Thornhill, ON installed on my roof automatically searches
for the satellite even as my wife and I drive down the road. Since
the antenna tracks the satellite even as you go around corners,
it is possible for passengers in a motorhome to watch their favourite
program or listen to CD quality music.
KVH has been one of the world leaders in the
satellite communications business for years, providing systems
for land and sea to the military, buses, trains, and cruise ships
that ply the seven seas. They have received the Best Product Award
from the National Marine Electronics Association for the last
three years.
The KVH antenna mounts on the roof in a 32-inch
diameter housing that is only 14 1/2-inches high and does not
need to be raised or lowered for travel like a regular TV antenna.
When you are getting ready to leave the campground, all you have
to do is turn on the power switch so that the antenna can continue
to point at the satellite, even as you drive.
The L3 antenna can turn up to 30 degrees in one
second. That means you will not lose the satellite unless you
go around a 90-degree corner in three seconds (hard to do in a
motorhome). Even if you park off level, the antenna compensates
automatically to continue holding the satellite signal. Two motors
inside the housing keep the dish pointed in the right direction,
one for azimuth (horizontal rotation) and the other for elevation.
TV reception with the dish depends on the antenna
being able to see the satellite. If you park your RV in a heavily
forested area where the trees block out the sky, you will have
difficulty with reception. By mounting the antenna towards the
front of the RV it is easy to get a clear view of the sky from
most campsites. However, on a trip to Alaska, we had to move our
RV to improve reception after parking behind a tall building that
blocked the antenna’s view of the satellite.
Normal home-style antennas mounted on a tripod,
or the crank-up style, need to be covered to prevent heavy rain
from falling between the dish and the LNB receiver and interfering
with the signal. This is not necessary with the KVH since it’s
housed in a weatherproof ABS plastic cover, called a radom.
Mounting the antenna on the roof was simple. An
aluminum plate was fastened to the roof and caulked so that there
would be no leaks. Then the antenna in its plastic case was carried
up and screwed into place. The TracVision L3 has a dual LNB receiver
so two receivers can operate on separate channels at the same
time, or a TV and a computer hooked up to the Internet. A 12-volt
power cable, a data cable, and a coaxial cable were routed to
a hole in the roof and down inside to the TV. Of course, Jeff
sealed the hole where the cables came through to prevent moisture
damage inside the coach.
KVH also builds other satellite receiver models
including the TracVision SA designed for stationary use at a cost
comparable to old-fashioned fold-down satellite antennas. It does
not have to be stored during travel like other types of antennas
that would be bothered by wind, rust and corrosion. When it comes
time to go on the road again, we simply unplug our ExpressVu receiver
from the TV set in the living room at home and move it into the
motorhome. As soon as we turn on the power, the antenna searches
for the satellite and stays locked on as we travel. We have the
same TV programs available on the road that we have at home.
