Detailed Description
The Valcom Model V-147-CL2-TH is a heavy duty, field proven, high reliability, coil-loaded. 49-foot whip antenna. The base and second section are inductively loaded to the resonant frequency specified by the customer.
​
This antenna incorporates notable features of two field-proven Valcom antennas:
​
-
Base section of the Canadian naval whip antenna AS-5085/SR
-
Loading section design of Valcom's low frequency whip antenna V-33070
Pedestal Base
The pedestal base mounts the antenna to its foundation. The base is made of a continuation of the same high strength filament fibreglass used in the antenna. The result is an integral base insulator with exceptional electrical and mechanical properties.
​
Power handling capabilities are improved while eliminating the weight of conventional brass and porcelain insulators. The shape transmits the bending moment evenly to the base mounting bolts.
Two Standard Configurations
-
The V-147-CL2-TH is available with a number of optional configurations to meet various system and installation requirements.
-
Optional configurations include:
-
Side-feed or feed-through models
-
44 to 49 ft heights ( useful for 50 ft height restrictions where tower is installed )
-
With or without Top Hat radials
-
With or without loading coil
For the feed-through model, a heavy duty galvanized steel tower VTGS-20BH is available in two-foot increments up to eight feet. These towers are used with both models to clear obstructions and the snow line.
