Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines

Antennas are structures or devices used to collect or radiate electromagnetic waves.

Communication tower erection services build communication towers, set up satellite dishes and install related communications equipment

Cooling towers are defined as any open water recirculation device that uses fans or natural draft to draw or force air to contact and cool water by evaporation

Tower lights, stack lights, and machine lights are used for alarm and machine status indication. They can be supplied with audible alarms and be used as flashers or steady light configurations

Radios are communication systems that send and/or receive electromagnetic waves. Devices such as citizens’ band (CB) radios, walkie-talkies, and handie-talkies are two-way radios that can be used for interpersonal communications

Wireless modems transmit modulated data using electromagnetic waves.

Terrestrial and satellite radio service providers transmit radio programming over satellite, cable networks and over open airwaves

Radio modems are radio frequency transceivers for serial data. They connect to serial ports (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem

Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment

Telecommunications infrastructure services include setup, maintenance and consulting for all data and voice communications technologies.

RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function

S meters (strength meters, signal-strength meters) measure the strength of signals in communication systems such as receivers and transmitters.

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI
