Abstract:

A measurement program was conducted to assess the potential effectiveness of the Tapered Aperture Horn Antenna TAHA, at LaPlata, Maryland in a polarization diversity reception system. Measurements were made at LaPlata on HF test signals transmitted from Hawaii and Davis San Francisco stations. The results indicated that the two polarized components received on the two ports of TAHA have very low correlation coefficients under all ionospheric conditions encountered during a four day test period. The distributions of signal-to-noise were computed to determine the degree of improvement afforded by using TAHA in a polarization diversity system. Author
