When the tears would happen, they would patch that area with screen to cover the hole and maintain continuity. Can this patching create a problem with site attenuation, if there are too many patches? I was planning to build the site with concrete underneath the screen. Also, do you know of a way to do the site attenuation faster? In the past, I have used tunable dipoles (takes forever) and also broadband antennas, which is a little faster. Normally, I have done the site attenuation with the signal generator about 10 feet behind the transmitting antenna. This means that you have to go outside, change the frequency, go inside and make the measurement, then back outside again. All I have to work with is a signal generator and spectrum analyzer. Would it make a difference to have the signal generator inside the building (this means that the output cable to the antenna would be approx. 30 feet long.) I guess as long as this long cable for the transmit antenna is counted in the "V direct" reading, it should be ok? Making site measurements faster will help me evaluate my proposed site location.
