(1,913 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

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


(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

(297 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

(317 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

(562 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) a measure of the quality 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...

Operational Amplifiers

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

RFID Transceivers

(40 companies)
Since the frequency of the tag is directly related to the geometry of the antenna, the frequency which it uses cannot be changed, but the depth of its modulation is adjustable. One of the central advantages to an RFID transceiver is the time saved...

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.


(399 companies)
...consist 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...

RF Headends

(22 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.

Eye Nuts

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

RF Repeaters

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