new DRM transmitter, an ASI CE-50000WS, was installed in April 2018. The
transmitter is rated at 15 kW and is using the Rhombic antenna at 062
degrees. The authorized schedule for this transmitter is: Monday-Friday
0700-1000 on 7315 kHz, 1000-1200 on 9265 kHz, 1200-1700 UTC on 13690

WINB transmitters feed a Rhombic antenna via an open wire feed
lines. The antenna is 640 feet long and 110 feet above the average
terrain. The principal radiation direction is 242 degrees true, or
almost due southwest. Minor lobes exist to each side of the main
lobe and to the rear on a bearing of 062 degrees true. The pattern
when the antenna is fed in the 062 direction is the same as 242 rotated
