R in a Circle (Airport Surveillance Radar) on VFR charts

Nantucket has the only (R) in Cape Approach's coverage area.


Otis ANGB has an (R), and I believe that's where Cape Approach is located.



Does this mean that the only radar antenna for Cape
Approach's coverage area is at Nantucket? I ask because there
is a large radar antenna in Truro, Mass (Cape Cod). On the
sectional, it even says "radomes" as a landmark feature near Truro.
Perhaps this antenna is for Cape Approach, although I suppose it
could be for Boston Center, weather, or who-knows-what. If it
is indeed a Cape Approach antenna perhaps it would be useful to
have the R on the chart.


That's the North Truro ARSR site, and former North Truro Air Force Station.
It's used by Boston and New York ARTCCs.
