Stacking requires a higher tower in order to get the same angle of radiation. The difference in GPS is that it is the delay, not the angular deviation caused by the changing density of the atmosphere that is of primary interest.

What is most important, high up in the mountains or a low angle of radiation?

The Effect of Atmosphere on Earth

The scatter angle should be as small as possible as each degree of scatter angle cost 9-12 dB in signal strength. Hawaii to California at 4000 km. th Tuesday of the month: 50. If this station uses the same 15-meter high antenna, the path loss will be 216. There are many possibilities: Meteorological: - inversion - ducting Reflection: - earth moon earth, EME - meteor scatter, MS - airplane reflections Artificial: - satellite transponders Ionosphere: - ionosphere scatter, IS for 50 MHz - sporadic E-skip, E S - aurora - trans equatorial propagation, TEP - field aligned irregularities, FAI 8, January 1958, p.

It is exceptionally rare that such signals made their way to the island despite being out of the tropo season. If the antenna is raised to 30 meters, this loss drops 208. The second was that the scatter loss at a 1- degree scattering angle about a 90-mile path was 57 dB at 400 MHz. It's derived from the way in which the antennas couple with the scattering process and may be associated with phase incoherence resulting from scattering by multiple random atmospheric inhomogeneities.

Anyone who has had a bumpy ride in an aircraft has felt this first hand, just as anyone who has seen a star twinkle has directly observed the optical effects of atmospheric turbulence. Signal polarization is well preserved during troposcatter transmission and transmission loss and signal fading do not depend on which polarization is used.
