On this website it’s been learned that AM antennas cannot share the same antenna location, the way FM & TV antennas can.
What has been mentioned is that FM and other VHF antennas can share the same tower by being separated by 1/4 wavelength, which is a short distance.
But AM wavelengths require totally separate real estate locations because 1/4 wavelength is a lengthy distance.
These thoughts are going through review as I anticipate placing the new AMT5000 into service when it arrives in the soon future.
Already I have two AMT3000s separated by about 100′ transmitting at 1550 and 1680kHz. There is also a dipole stretched from one of those locations to the other operating at 13.560mHz, and that signal gets into my 184.3mHz wireless mic receiver, and my 101.9mHz STL is catching an image of the station at 102.5mHz, which can be heard in the background on the 1550kHz audio. It’s o.k. if this description can’t be followed, it makes the point that locating transmitters becomes more and more complex as new ones are added.
It will only get worse when two more installations go into the mix: 970kHz AM carrier current, and 153kHz long wave.
Got to stop expanding.
Oh, almost forgot the revived CB transceiver that’s going in.
