When space is at a premium, outdoor equipment is
unattended and you want an attractive way to
install your AM antenna, 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 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.
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
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.
Our patented the VP9000 antenna design (US
Patent 7,027,008), may be optionally used with the
information radio systems:

Information Radio Stations is a generic term synonymous with Travelers
Information Stations (TIS), Highway Advisory Radio Stations (HAR) /
Highway Information Systems & Low Power Radio Stations (LPR). Operation
of the stations is governed by FCC Part 90.242 Rules. A FCC license is
required. Information Radio Stations may be fixed or portable.
Subcomponents may include transmitter, antenna and ground system,
digital voice player, wattmeter, cabinet with conventional or Corbin
locks, lightning arrestors for RF, power and telephone lines, coaxial
cable. Most stations employ black maximized antennas to discourage ice
accumulation and security measures to prevent unauthorized program
access. Options include synchronization, battery backup, solar power,
remote programming by local, network or telco, multi-station audio
distribution via RF or LAN / WAN or wireless network.
