Too bad these antennas were all torn down around the state of Alaska during the 1990s.Sure, they were located in Fort Yukon, Alaska I took them around 1990 before they were demolished. If you want to read more about the technology look up "White Alice Communications System. They used frequencies around 900 Mhz.
I once read an article by an old time broadcast engineer that reported these antennas were great for AM radio reception. An explanation about connecting a portable battery operated AM radio to a ground connection on the White Alice array, and getting consistent reception of broadcast stations from hundreds of miles away, and who knows what at night? Alaska was a much more interesting place to tinker back in the good old days. How about FM reception from Anchorage throughout the west end of Denali National Park, via knife's edge refraction from 20,000 foot reflectors otherwise known as the Alaska Range? It seemed to work continuously from a visitor center starting about 65 miles into the park, and many miles west and northwest to the Lake Minchumina area. Found this by accident in 1976, and later research told me that it had been known as a local secret by miners, who also had discovered its abilities to extend Anchorage analog VHF TV channels over the same four mile high reflector.
