Rayzar RZ8535 is pictured above located on the
roof of the RV so that you can get an idea of
its size. It is 7" high and 18.5"
wide (including the attachment legs) with a
UV protected plastic dome. The operating voltage
is 10 - 13.8 VDC. The unit weighs 4.5 lbs.
The Wingard Rayzar instructions do say not to
install the antenna on or near metal objects.
This mentioned for RV's with a metal roof.
The Winegard Rayzar comes in the following models:
RZ-7500, RZ-7535, RZ-8500 (white) and the RZ-8535
The approximate selling price of the Winegard
Rayzar is $359.00.
In the box is a roof plate, a ceiling plate,
a roof cover plate, a single entry cable plate,
a 72 inch coax cable, a 20 foot coax cable,
hardware and a control panel.
The roof plate and ceiling plate are supplied
to cover an existing hole made for an antenna
that is already on the RV. The Rayzar does not
require any holes in the RV roof to install
it as it mounts onto the roof with screws. One
would route the cable down through the existing
antenna hole or drill a small hole for the cable.
The control panel is installed in the RV. If
there is a control panel from an existing antenna
then one simply replaces that with the new control
Below is a picture of the Rayzar control panel
with an explanation of what each feature on
the control panel is for.
For testing we used the 1998 Batwing Antenna
on the RV elevated to full height, and a 19"
flat panel TV. We used the same TV for both
tests. As the Batwing Antenna is directional
we adjusted it 4 times - 12, 3, 6 and 9 o'clock
positions and recorded the total number of channels
found at each position, we then used the most
channels found as our result.
We then connected the Rayzar control panel and
ran 6 scans on the TV. The Rayzar control panel
has a positive and ground to connnect a 12v
supply to, and then antenna in, Cable in and
TV out connections. When the control panel is
turned on one can hear the Rayzar units motor
start hunting for channels up on the roof. As
the unit hunts for the best direction for channels
the LED's on the control panel show in which
direction the unit is rotating. After 2 - 3
minutes the control panel will show the TV frequencies
found at the current position. This is the number
of RF signals available. The actual channels
found on the TV will be 2 to 3 times more than
this number due to multi-casting.
Below are the test results from each antenna.

if you have an existing Winegard Sensar antenna,
there is a Winegard
SensarPro (links to Amazon product Information)
control panel that is helpful in finding the
strongest signal strength. Slowly rotate the
Sensar antenna until the strongest signal strength
is located then run a channel scan. This ensures
you have the antenna pointed at the strongest
signal source and you do not have to run multiple
TV scans to find the best signal strength.
Rayzar Picture Quality
There were a few channels
(2-4) where the channels were pixelated and
breaking up which would nornally require a small
adjustment of the antenna. We did not get the
same breaking up on those channels with the
It seems that the Batwing crank up antenna still
has the advantage of height over the Rayzar
and the Batwing is manually operated with fewer
working parts to break down.
It's a postive for not having to drill holes
for a crank handle and the unit self adjusts
to the best position for channels. Some RV's
have high ceilings and it's a positive for not
have to try and reach the crank handle. If you
do not have any problems reaching the crank
handle, upgrading from a Batwing antenna to
the Rayzar might not make much sense to existing
If you find yourself doing multiple TV scans
trying to find the best quality signal then
it would be cheaper to puchase the Winegard
