A boardwalk is required to get to KVI Beach and the transmitter site.  The tide rolls in to the left and fills the depression with water, and runoff from Vashon Island also fills the depression.  The entire length of steel produces the signal and is energized.

The tide comes in and almost surrounds the KVI antenna at Point Heyer.  FM and TV need to be on high hills, but not AM.  Conductive terrain is the most important for AM radio, and KVI has the best location of any AM station in Puget Sound.

The tuning unit for KVI’s antenna is located inside the base of the 431 foot radiator. The entire length of steel is required to make the KVI signal. Storm whipped waves spray the shack in the winter.

KVI's 431-foot antenna dips its toes in Puget Sound at Point Heyer on Vashon Island. 120 buried copper wires extend from the base of the antenna like bicycle spokes, and actually extend into the salt-water.

The City of Seattle is visible in the background of this shot of the KVI transmitter site.  AM transmitters are commonly found in shoreline and floodplain environments.

"KVI Beach" is privately owned by Fisher Radio, though Fisher allows people to use the beach as a park.  The location is an ideal setting for AM signal propagation.
