Vertical Profile Antenna System

Vertical Profile Antenna System
US Customs Traveler's Information Station
Tucked along Walled Courtyard at US Customs & Border Protection's Laredo, Texas, Port of Entry


Fort Bend County, TX, ALERT AM System
Yard-Style Installation at Fort Bend County, Texas, Emergency Operations Center

Placement was . . .
  • 50' from the building with no paving for the buried cable to cross.
  • Nearby obstructions taller than 20' were as far from the pole as they were tall. See separation diagram.

The County installed multiple synchronized ALERT AM stations with VP9000s. See case study.

When space is at a premium, the Vertical Profile Antenna System (VP9000) offers the solution. Place the VP9000 System in the yard adjacent to a building or outdoor cabinet, where information radio equipment is located.

The Vertical Profile Antenna System consists of an attractive painted aluminum antenna support pole and antenna grounding system, all in one. The antenna lightning arrestor and all cables are inside the pole, accessible through a service hatch. There is nothing on the surface of the pole to encourage vandalism.

Advantages: Minimal ground disturbance (less than one square foot, horizontal; six-foot depth, vertical). No additional antenna groundplane or rod are required; therefore, it is an easy antenna system to move.

This antenna system is recommended for high visibility areas and features low vandalism potential and low installation cost. The support pole with a 1400-1700 kHz antenna meets and exceeds Florida's hurricane-force wind specifications (see "Specifications" below).

Installation Requirements: Place the Vertical Profile Antenna a minimum of 50 feet from building in grass, dirt or paved areas. See a separation diagram. Vehicles may be parked next to the system; however, the support pole should be guarded from vehicle damage. Coaxial cable to the support pole may be buried or installed overhead. The pole is set in a 6-foot post hole with good earth contact in the lowest 4 feet of the hole. (When used on AM frequencies below 1000 kHz, a 20-foot solid ground rod is driven beside the pole.) Concrete, asphalt or tamped dirt may surround the pole within 2 feet of the surface.

We have engineered the Vertical Profile Antenna System to comply with the ANSI/TIA standards. This means it is rated to perform in worst-case environments, such as, unobstructed shorelines in hurricane-prone areas and atop ridges in terrain where wind speeds can achieve great force. Additionally, it is rated for essential communications in critical areas where failure of a structure could damage buildings or present a hazard to life. To achieve these designations, the VP9000 has to be able to sustain 130 mph/3-second gust winds without failure. The Vertical Profile Antenna System is compliant with ANSI/TIA-222-G-2005 (Class III, Category 4, Exposure D) Standard for frequencies 1400-1700 kHz when installed in soil types per Annex F of the standard. In a separate study, when used with AM frequencies 1400-1700 kHz, VP9000 was rated to meet increased coastal hurricane wind-speed requirements (150 mph in a 3-second gust) for South Florida and other coastal areas.

The VP9000 antenna design may be optionally used with the following information radio systems: Bill Baker (616.772.2300, x102) will help plan your station, select options and provide a formal quote. Lease-to-own programs are available.

Illustrated instruction manuals come with every station, and we offer technical support for the life of the product 24/7.
Advantages over Conventional Buried-Radial Groundplanes with Wood-Pole-Mounted Antennas
  • Simple one-piece design.
  • Requires little disruption to sites (only 1 square foot).
  • Buried copper element is less likely to be stolen.
  • More attractive than standard wood-pole antenna supports.
  • Hurricane wind rated (130 MPH, 3-second gusts) for all frequencies.
  • Meets most stringent Florida coastal standards (150 MPH, 3-second gusts) with 1400-1700 kHz frequencies. Support pole with antenna is ANSI/TIA-22-G-2005 compliant (Class III, Category 4, Exposure D) for 130 MPH/3-second gust for 1400-1700 kHz.
  • Pole does not burn in wildfires.
  • Moderate overall cost (hardware plus installation labor) as buried-radial groundplane antenna.
  • More simple to move if ever required than other grounding methods.
Specifications
  • Space requirement: less than 1 square foot.
  • RF grounding element: 4-foot length; integral to support pole.
  • Lightning ground: 8-foot groundrod, copper clad.
  • Support pole composition: aluminum, 6-inch OD, .3125-inch wall thickness.
  • Support pole length: 24 feet.
  • Support pole finish: powder coat, silver/gray.
  • Support standing height: 18 feet above grade; 6 feet below grade.
  • Wind: hurricane rated. 1400-1700 kHz, support pole exceeds Florida Dade/Broward County wind load requirements with attached antenna, greater than 146 MPH/3-second gusts. 530-1390 kHz, support pole meets and exceeds Florida wind load requirements with attached antenna, 130 MPH/3-second gusts (Florida Building Code – 2001).
  • Internal components: RF lightning arrestor, grounding bus, coaxial feedline:
  • Provided in a weatherproof NEMA4 cabinet, arrestor bonded to an aluminum panel that supports the lightning grounding and groundplane connection clamps. 
  • Capacity of 50,000 amps surge. 
  • Clamping speed of less than 2.5 nS. 
  • 2 UHF connectors. 
  • Aluminum flange ground connection. 
  • External components: threaded attachment for antenna mount, weatherproof service hatch with tamperproof hardware. Crane hook.
  • Frequencies: 530-1700 kHz.
  • Compliant with ANSI/TIA-222-G-2005 standard (Class III, Category 4, Exposure D) 130 mph/3-second gust for frequencies 1400-1700 kHz when installed in soil types per Annex F of the standard.
  • Maintains safe human RF exposure distance from the AM antenna, per FCC Guidelines (per ANSI/IEEE C95.1-1992 standard).
