28 January 2015:
A new international standard definition of the antenna reference point (ARP) has resulted in a vertical change for two multi-configuration antennas with removable adapters or special-purpose masts. These and similar, recently added antennas are listed below to help you identify your ARP and determine your antenna height.
Refer to the antenna calibration drawings to locate the ARP for your antenna type. You will need this to properly measure your antenna height, or compute it using a slant height measurement.
If you used one of the antennas listed below and measured only to the bottom of the adapter or optional mast, then you will need to add the length of that adapter or mast to bring the total antenna height up to the ARP. The table below provides known height offsets for some adapters or poles.
