Chris, The rule that supersedes the others is: Don't interfere. However... there's a general perception that Class A is cheaper to build than Class B and not to ask for stricter standards if aiming at a better deal. This can result in specifying Class A limits if there is any justification at

Great dialog, just the path that I was hoping would develop. One thing I have learned since the question was first asked, all biconical antennas are not made equal. The original antenna calibrated at an outside test organization, exhibited a 5 dB difference between the vertical and horizontal
