"David Harper" wrote in message m... I was wondering what the general relationship between frequency and its ability to transmit through various materials? For instance, 1GHz and 1MHz obviously transmit differently through materials. I'm curious as to what material properties are involved (i.e. dielectric constant, density, etc?) The main reason for this questions is I'm wondering how well 1+ GHz (GPS) signals transmit through about 1.5 inches of expanded polystyrene (styrofoam). Thanks in advance for any insight! Dave Dave How much of *what you want to know* could be learned from a test in the microwave?? As you probably know, it will be very difficult to include enough Polystyrene around a GPS receiver (and its antenna) to effect the accuracy of its readings. I get pretty good accuracy from my DeLorme GPS while it is inside my house. That is actually a statement about the poor construction of the house, I suppose. Jerry |
