LIGHTWEIGHT FLEXIBLE VHF TREE-TOP ANTENNA WITH INFLATABLE MAST.

Abstract : This program was a research and development effort to improve the portability of VHF antenna systems for military field use. A variety of devices were fabricated which strive to provide an evaluator with meaningful parameters of sizes, weights, durabilities, effectiveness, overall acceptability, etc. Highly mobile means of providing respectable communication ranges in jungle areas are of prime importance. A basic guideline used in this program was an adaptability of techniques or devices for more than one application. For instance, the 'J' antennas are used interchangeably with their chosen elevating device, be it mast or AEROKITE. The same inflation fitting is used on the mast and on the AEROKITE. Although the electrical devices are designed to be compatible with the elevating devices, they have not been incorporated together as unseparable components. It may be desirable to do so in future applications. Both elevating means are inflatables and require some adaptability by the user. One must realize that a lightweight system will lack durability and be subject to wind loadings. Where portability and effectiveness are of great importance, this trade-off is readily acceptable.
