Model 6025 Full-wave Spaced

Specifications:
Frequency Range:88-108 MHz
Elevation Gain:
(single bay)
1.15 (0.606 dB) in vertical or horizontal position
0.55 (-2.59 dB) in slant configuration (45° angle)
Power gain:H & V: 5.07 (7.05 dB)
Slant: 2.53 (4.03 dB)
Impedance:50 Ω
VSWR:< 1.28:1
Polarization:Vertical, horizontal, or slant (45 ° ) polarization or custom H/V ratios.
Maximum input power:5 kW per element, rated at power divider handling for multiple levels
Input connector:7/8" EIA for single element, 1 5/8" or 3 1/8" EIA on power divider for multiple element arrays.
Standard Mounting:Designed to attach to a customer-supplied 1-1/4" pipe (1.5" OD) - 3" pipe (3.50" OD) or similar tower leg. Standard mount has positioning built in for vertical, horizontal and slant (45°) mounting.

Includes downward support tension device for added support over the length of antenna.
Also includes anti-rotation arm kit to attach to tower.
Custom mounts:Option for up to 5-1/4" leg diameter available at additional cost - contact factory.

***Gain values are for 93.1 MHz (low-band) and 103.1 MHz (high-band) and vary less than 5% at the edges. Our gain figures are calculated by factoring the directivity to allow for losses in the radiating system. Due to this conservative approach, you are assured of radiating maximum ERP by using Shively’s published gain figures. 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 H/V ratio, or special wavelength spacing is provided.

Notes:
WINDLOAD TABLE(S)
1. Antenna radiation aperture is the distance from the center of the top bay to the center of the bottom bay. Five feet (1.5 m) of the pipe is required above the top of the top bay and below the bottom bay. Total tower space recommended allows ten feet (3 m) of clear tower space above the center line of the top bay and below the center line of the bottom bay, to protect from pattern interference by other antennas. At frequencies lower than 98 MHz, each of these dimensions will increase by up to 1 foot (0.3 m) per bay.
2. Windload and weight tabulations assume full-wave bay spacing and include the bay, mounts and interbay feedline.
3. Antenna areas and weights calculated in accordance with TIA-222-G. EPA(N) – Effective projected area associated with the windward face normal to the azimuth of the antenna: EPA(N) = (Ca AA )N EPA(T) – Effective projected area associated with the windward face at the side of the antenna: EPA(T) = (Ca AA )T Assumptions: Structure Class II; Exposure category C; Topographic category 1; Maximum basic windspeed 90 mph; with 1/2 inch design ice, 40 mph; Maximum height above ground 200 ft.
4. Ask for technical assistance at Shively if you are planning to mount antennas on AM towers or install them at altitudes over 3,000 ft (915 m) above mean sea level.
