Typical Data for
Model 6016P FM Panel Antenna

• True Circular Polarization
• Broadband 87.5 - 108 MHz; Designed for Multistation Use
• 15 kW Average, 100 kW Peak Power Rating per Panel
• Designed for 4-Sided Towers
• Omnidirectional ± 2 dB
• Directional Versions Available
• Minimum Maintenance
• Stainless Steel Construction

Electrical Specifications (United States):

Electrical Specifications (Overseas):

• Gain = azimuth gain + elevation gain

Notes:

1. Our gain figures are derived from the computed directivity and include the losses in the antenna feed system. Gain is computed for 98 MHz and will vary across the band.
2. Gain is provided for one polarization and is equal in circularly polarized antennas for both horizontal and vertical components. Gain will be reduced if special wavelength spacing is provided. Gain will increase in a directional array by the directivity of the azimuth pattern.

Performance Specifications:

Polarization:

Right circular.

VSWR:

1.15 : 1 over the FM band.

Azimuth Pattern Circularity:

Horizontal component ± 2 dB on a 5-ft triangular tower.

Power Rating:

15 kW average per panel

100 kW peak per panel.

Input:

1-5/8" - 6-1/8" EIA. Single and dual inputs available.

Size and Weight:

Windload:

Notes:

1. Vertical apertures are approximate, consisting of the distance between the top edge of the top panel to the bottom edge of the bottom panel. Contact us for the exact antenna aperture for your frequency.
   Please do not confuse vertical aperture with tower space needed for proper installation. Tower space required is greater. Contact us for details.
2. Windload and weight figures are approximate values and should be used for estimating purposes only. They assume a typical omnidirectional (4 panel per level) pattern. The figures include radiators, panels, panel hybrids, and a representative single input feed system. No values are included for mounts. The values for mounts, complex feed systems, and directional arrays may significantly affect these estimates. Please contact the factory for an estimate for a system to meet your specific requirements.
3. Antenna windloads are calculated for 112 mph (180 kph), using 50 psf (2400 N/m²) for flats and 33 psf (1600 N/m²) for rounds] per EIA standard RS-222-C and CSA standard S37-94. The surface area is calculated per EIA standard RS-222-F (CaAc).
4. Ask for technical assistance at Shively if you are planning to install antennas at altitudes over 3,000 ft (915 m) AMSL.
