TECHNICAL INFORMATION
The following information will address TV antennas and attempt to give some insight into how TV
antennas and their application affect television performance.
UHF/VHF FREQUENCIES
VHF (CH 2 - 13) and UHF (CH 14 - 69) signals are nearly identical with one critical difference:
“wavelength.” VHF wavelengths are longer than UHF wavelengths. Therefore, the best antenna is
one that closely matches the wavelength of the signal you are trying to receive.
Also keep in mind that VHF wavelengths are significantly reduced when obscured.
ANTENNAS
Following are a few points to consider in regards to installing and choosing an antenna:
Metallic Paint
Manufacturers of boomerang antennas warn users that painting antennas with metallic paint will
hurt performance. This is also true for foil antennas used in fiberglass high tops that are painted.
Outside Metal
When TV antennas are used inside low top van conversions, the TV signal can be obstructed by the
outside metal of the vehicle. This will diminish UHF performance and may eliminate VHF reception
altogether. However, depending on antenna’s location and the direction of the vehicle, some VHF
signal may be received.
