Forestport Antenna Study
Abstract
Feasibility study was made of the USAF Forestport, N. Y., VLF navigation antenna to increase its power radiating capability to 500 watts. Ten possible top-hat configurations were investigated by scale-model techniques. The model ranges and antennas, instrumentation, and methods of measurements are described. The results of the model study (electrical parameters and power-radiating characteristics) are presented quantitatively for each of the configurations studied. Radiated power measurements of the present full-scale Forestport antenna showed some disagreement with the model results. This was believed due to a calibration error in the antenna current measurement circuit of the Forestport antenna. The maximum antenna voltage of 109 kv was established as one of the design criteria for the increased power of 500 watts. Several of the configurations met or exceeded this power vs antenna voltage requirement. The most economical configuration is recommended. It is further recommended that additional insulation be provided to increase the safety factor of the modified antenna.
