146.67 Technical Specifications
West Palm Beach - Repeater Site
|The AREC Repeater site is located at
a tower owned by West Palm Beach near 45th Street and the Turnpike in West Palm Beach. The repeater
is a Quantar, manufactured by Motorola, and is located in an
air-conditioned Palm Beach County radio shelter. It is set for 80 watts output
and is capable of P25 operation. Periodic announcements are made from a remote site. The repeater is on a UPS which has emergency generator backup power.
The antenna is a DB-224E by Commscope/Andrew Corp., a 23 ft tall vertical mast with
four stacked full-wave folded dipole elements, providing high gain and
broad bandwidth, fed by 7/8" hard line. The antenna is located on the SW side of the tower with
all four elements pointing West. The base of the antenna is about 355 feet
This configuration gives us approximately 9 Dbd gain to the West and about 7.5 Dbd gain to the North and South, providing excellent coverage over Palm Beach County (these figures are from the data for this antenna published by Andrew Corp).
The PL Tone
|The Repeater uses a PL tone of 110.9 for the purpose of reducing interference from other 146.67 systems in Florida. The PL tone may be turned off during emergencies, SETs, preparedness drills, or any other situations where unrestricted access is desirable. This frequency complies with the Florida Repeater Council Guidelines.|
