Radio systems  must be deployed with the proper antenna systems including antenna, cable, lightning protection, and mast/towers. This section  describes selection of antenna systems.

Radio and Cellular Modems can operate in the following bands – VHF, UHF (hi and low), Spread Spectrum, WiFi.

Antenna Impedance

Antenna are typically 50 Ohm Impedance.

 VHF 130 – 200 MHz Voice Communication, Licensed radio
 UHF 400 MHz Licensed Radio
 Spread Spectrum 902 – 928 MHz License Free Application
 WiFi 2.4 GHz Wi-Fi, a, b, g, n
 5.8 GHz n, ac
 Cellular 700 MHz LTE / Data / Voice
 800 MHz / 900 MHz Data / Voice
 1700 MHz / 2100 MHz AWS
 1900 MHz / 2600 MHz Data / Voice

Antenna Types

Omni Base Station Antenna

Omni-directional base station antennas systems are used for fixed site applications where a central or repeater site must communicate to remote sites in multiple (omni) directions.  For systems covering wider areas, the base station antenna would be mounted on an elevated mast or tower. For systems covering  shorter distances low gain omni antennas may be used.

Directional Antenna

Directional (typically YAGI) station antennas are used for fixed or portable sites to communicate to Master site or Repeater site in a Point to Multipoint Systems, or for Point to Point Systems. Antennas are mounted on masts or tower to clear terrain obstructions.  The directional antenna can be  YAGI, reflectors, or parabolic dishes. Antennas for areas with severe icing may require radomes on the complete antenna or the driven element.

Mag Mount Antenna

Mag mount antennas are used for mobile  or short distance fixed site applications. Mag mount antennas with no ground planer design if mounted on non-metallic equipment to insure adequate ground plane.

Whip antennas are connect directly on devices  for testing to communicate within a laboratory or shop. Whip antennaes are not recommended fixed site installation where the antenna can be obstructed by buildings, vehicles,  equipment or enclosures.

Specialty Antennae

Specialty antennas including  in-ground, flush mount, or multi-band antennas may be used.
