RCA "TRAVELING
Combines Improved Electrical Characteristics
Here is a VHF high-band antenna that has inherently low VSWR and produces smoother patterns. The design, based on slot radiators, results in improved circularity. This new antenna is strongly resistant to high winds and offers better weather protection.
INHERENTLY LOW VSWR
The traveling wave nature of the feed results in a low VSWR along the antenna. This characteristic gives the antenna an inherently good input VSWR without compensating or matching devices. The input has been broad-banded to provide a smooth transition from the transmission line to the antenna.
EXCELLENT VERTICAL PATTERN
The null-less vertical pattern is extremely smooth. This provides uniform illumination of the desired service areas. Gains from 9 to 18 can be obtained.
IMPROVED CIRCULARITY
The individual patterns produced by slot radiators when added in phase quadrature result in an overall pattern with improved circularity. This design combines radiating elements, feed system and antenna structure in one unit, giving excellent horizontal circularity.
LOW WIND RESISTANCE
The smooth cylindrical shape of the antenna is ideal for reducing wind load and has high structural strength. It is designed to withstand a wind pressure of 50 psf of flats, or 33'/3 on cylindrical surfaces. In addition, the absence of protruding elements minimizes the danger of ice damage.

The Popular Choice of Broadcasters for High Power TV Applications
WAVE" ANTENNA
J with Mechanical Simplicity and Economy
The steel outer conductor is hot-dip galvanized for better conductivity and protection. The inner conductor of the antenna is rigidly supported at the bottom end without relying on any insulator type of support to carry the dead weight. Polyethylene slot covers are fastened to the pole over every slot for better weather protection.
SIMPLIFIED FEED SYSTEM
The feed system is completely self-contained with only one point of connection. Simplified feed system consists of a large coax line and coupling probes. Completely enclosed by heavywall steel shell, thereby minimizing possibility of damage and off-air time due to "lightning discharges."
HOW THE "TRAVELING WAVE" ANTENNA WORKS
Essentially, the RCA "Traveling Wave" Antenna is a transmission line with slots cut into the outer conductor. These slots are arranged to guide the energy radiated by the center conductor into the needed radiation pattern. It fills the need for a VHF High-Band Antenna which combines mechanical simplicity and economy, especially in high-gain, high-power applications.
