Thank you again for the info. I have a pretty good understanding of radio wave propagation. I know that transmissions in the 30 MHz and above propagate via space or direct waves (attenuated by the earth's surface and pass directly through the ionosphere) and have a short (line of sight) transmit distance without repeater stations. Also, the higher the frequency, the more the signal begins to act like light and is more susceptible to man-made and terrestrial objects. Wavelength refers to the distance it takes for a signal to complete one 360 degree cycle (for 2.4 GHz it is roughly 4.92 inches). For me and my work experience it seemed to be unnecessary, due to the proximity of the two antennas, and the fact the it would seem that the would most likely be subjected to the same interference, to place the antennas at 90 degrees to each other. Your explanations are great although I am still a little skeptical on alignment of the antenna... but not so skeptical that I will test it out anytime soon

. I will follow your expert advice if I am ever in PPKK's shoes.
Thanks Again,
Brett
