For our review and testing of this product we decided to to use an older model RV that had a
1998 Winegard Batwing antenna. We wanted to see how old technology stood up against
this new automated product.
The Rayzar RZ8535 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. Pricing can be seen at the bottom of this page.
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
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. Unlike the Winegard Batwing, 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 Rayzar 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 panel.
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.
Tip, if you have an existing Winegard Sensar antenna, there is a Winegard SensarPro
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 Batwing antenna.
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 RV owners.
If you find yourself doing multiple TV scans trying to find the best quality signal then it
would be cheaper to puchase the Winegard SensarPro.
