Transformers

(1,905 companies)
Transformers are electrical devices that are designed to transfer energy from one circuit to another by electromagnetic induction. They are used typically to increase or decrease voltage as it passes from one side of the device through the other.

Cores and Tubes

(43 companies)
Cores and tubes are made of paper, plastic or metal and are used for mailing, shipping, material handling, and product display.

Radomes

(26 companies)
Radomes are weatherproof enclosures to protect an antenna from the elements. Radomes are more typically used on satellite or microwave antennas, but can be used with any antenna.

Signal Isolators

(145 companies)
Signal isolators provide electrical (galvanic) isolation between the input and output circuits. They couple the signal to the output through a transformer or optical isolator. Signal isolators also break the direct electrical (galvanic) path between two or more loop points. They are used to protect against dangerous measured-variable voltages and provide increased protection from surges and spikes.

Wireless Systems

(285 companies)
Wireless systems consist of combined RF components such as transmitters, receivers, transceivers, filters, down / up converters, antennas and antenna positioners.

Towers, Masts, and Poles

(309 companies)
Towers, masts and poles elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines.

Sensor Transmitters

(538 companies)
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA).

SWR Meters

(9 companies)
...of the match between the antenna and the receiving system. VSWR is the ratio of the maximum voltage to the minimum voltage on an electrical transmission line. In other words, it is a measure of the impedance mismatch between a transmission line and load...

Operational Amplifiers

(142 companies)
Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions.

RFID Transceivers

(42 companies)
...to antenna geometry, frequency cannot be changed but modulation depth is adjustable. One of the chief advantages of an RFID transceiver is the time saved; a module is able to read and rewrite a tag with only one input from the operator. RFID transceivers...

Link Chain

(224 companies)
Link chain includes loop, welded, weldless, sash, jack, ball, beaded, plumbers, safety, and coil chains for lifting, securing, lashing, mooring, rigging, security, keeping, traction, actuation and other applications.

RF Headends

(19 companies)
RF headends are electronic control centers, generally located at the antenna site of a system, which includes the antenna, preamplifiers, frequency converters, demodulators and other related equipment.

Radios

(384 companies)
...of a transmitter, receiver, and antenna. They are available in mobile and base configurations. Unlike cellular phones, radios do not require a monthly contract or carry per-call charges. In the United States, two-way radios are regulated by the Federal...

Eye Nuts

(74 companies)
Eye nuts (eyenuts) are fasteners with a looped head. They are designed to receive a hook or rope.

RF Repeaters

(115 companies)
RF repeaters have independent paths for reception and transmission, through which they collect and send signals to antennas and other stations.
