It is lightweight and has low wind loading. We manufacture this system in the USA with stainless steel construction for durability.

  • Economical- perfect for translators, campus, standby, aux and religious broadcasters
  • True Circular Polarization
  • No Pressurization Needed
  • Designed for Easy Mounting

Performance Specifications

  • Polarization: Right Circular
  • VSWR: 1.1:1 If tuned with transmitter metering
    for minimum reflected power.
    1.2:1 if tuned with mechanical dimensions
    and tuning data chart supplied.
  • Azimuth Pattern Circularity: Horizontal component + 1.5 dB on Pole
  • Input Connection: 7/16 DIN female for a single bay, 7/8″ EIA female for multiple bays

Notes:
WINDLOAD TABLE(S)

1. Standard mounts are designed to fit customer-supplied 1-1/4″ ips (1.5″ OD) – 3″ pipe (3.5″ OD) pole or tower leg.

2. Windload and weight tabulations are estimates and assume 98 MHz. No values are included for mounts. The values for mounts, complex feed systems and directional arrays may significantly affect these estimates. Shielding due to the tower has not been accounted for. Please contact the factory for an estimate for a system to meet your specific requirements.

3. Antenna areas and weights calculated in accordance with TIA-222-G.

  • EPAN – Effective projected area associated with the windward face normal to the azimuth of the antenna: EPAN = ∑(CaAA)N
  • EPAT – Effective projected area associated with the windward face at the side of the antenna: EPAT=∑(CaAA)T
  • Assumptions: Structure Class II; Exposure Category C; Topographic Category 1; Maximum basic windspeed 120 mph; with 1/2 inch radial ice, 40 mph.

4. Elements can be stacked or arrayed for omni or directional patterns.

5. System designed for maximum of 2″ factored radial ice (tis) at height using TIA-222-G specifications and maximum velocity pressure of 51.29 lbf/ft2 with no ice.

6. Ask for technical assistance at Shively if you are planning to mount antennas on AM towers or install them at altitudes over 3,000ft (915m) above mean sea level.
