The ASPSD917TGPS dual-system antenna combines GPS and cellular frequencies in a single antenna to give users two-way communication capabilities. It features elevated feed point technology, which was used in the first cellular mobile antennas. An Omni-Loc swivel allows for up to 25 degrees vertical angle adjustment, and an ultrasonic seal protects against rain and ice. The antenna operates at 824 to 894 MHz for cellular and 1575.42 MHz for GPS. The antenna whip is made from 17-7 stainless steel with a Dura-Coat finish.

The 100W1000A all solid-state amplifier delivers a minimum of 100 W of continuous wave power over a frequency ranging from 1 to 1000 MHz. It has been enhanced with a digital front panel and integrated IEEE-488 bus and offers more test control options accessible from front panel menus or remote locations. The minimum linear output power is measured at the 1 dB gain compression point and is 75 W over the same bandwidth. Forward and reflected power up to 150 W is displayed from the front panel. The amplifier will operate into any magnitude and phase of source and load impedance. Wide instantaneous bandwidth address RF susceptibility testing, antenna and component testing and watt-meter calibration. Amplifier Research

The FCD-10B clip-on coupling device works as an accessory to the VCS-20A fiber optic talk set to establish full-duplex communication anywhere on a network. It also can be used with power meter/loss test sets for 2 kHz tone detection. The FCD-10B works on a flat surface or in the operator's hand. The device features an extended wide area base with groove lines for fiber positioning, radial movement, a controlled damping mechanism and a protective stop for self-controlled clipping. EXFO E.O.

This enhanced selection of in-line single wavelength fiber optic attenuators are designed to allow fiber optic connector ferrules to maintain physical contact with the attenuator's components. The attenuators can be inserted in an in-line configuration and are compatible with SC, ST, D-4, FC or APC fiber optic connectors. They feature a non-air gap design and are stable in the 1310 nm wavelength range. Attenuation values from 3 to 20 dB are available in 1.5 dB increments for SC, ST and FC types. Attenuation values from 5 to 15 dB are available in 5 dB increments for D4 type. Siecor Corp.
