Marginal Antenna Placements

Antennas surrounded by poles, wires, large structures or trees cannot generate their full signal potential.

Superior Antenna Placements.

Compare against these antenna placements, which are in open areas of a yard or roof with no lateral obstructions.

Ideal Antenna Siting

The antenna may be installed on a 20’ pole located adjacent to a host building. We recommend a 50’ minimum separation between the building and the pole. (The pole may be provided by you or by us, depending on the contract.)

The building should have generator power backup, if the application is for public safety

The pole should be placed aside a building in which there are minimal paving or sidewalks for the buried cable to cross . . . in a yard area with adequate room for the pole and buried groundplane (if required) . . .in an area in which obstructions taller than 20’ are farther from the pole than they are tall (ex: 35’ tall tree is at least 35’ away).

If there is no suitable ground location and if the building has a flat roof, the roof may be considered under certain circumstances. Consult with us.
InfOspot Range Extender Outdoor Antenna and Tuner Setup
Not Optimum Recommended
The InfOspot Antenna and Tuner must be mounted to the very top of a pole or mast which extends above the mounting structure 3-5 feet (minimum.) It should not be side-mounted directly to the mounting structure (wall, tower leg, or pole), allowing the antenna to parallel the mounting structure. The antenna should not be allowed to parallel its support mast. This will cause the antenna’s signal to be dissipated into the structure.

For example, attaching the Range Extender Outdoor Antenna and Tuner to a stub just above a roof surface or alongside a wall, eave, gable or mast can yield less-than-ideal results because the antenna parallels the structure. Instead, attach it to the top of a mounting pole or mast, which allows the tuner and antenna to be raised above the supporting structure by a few feet. A separation of 3-5 feet is recommended.

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, wateter, 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
