ERAVANT
A sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern. The word "sector" is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc. 60°, 90° and 120° designs are typical, often with a few degrees 'extra' to ensure overlap and mounted in multiples when wider or full-circle coverage is required (see photos below). The largest use of these antennas is as antennas for cell phone base-station sites. They are also used for other types of mobile communications, for example in Wi-Fi networks. They are used for limited-range distances of around 4 to 5 km.

TRICOR Systems Inc.
TRICOR’s Hazer Meter and DOI is ideally suited for measuring flat, non-textured high reflectance surfaces. The Model 807A Haze Meter design is in accordance with ASTM E430 and ASTM D5767 (method A) and is used to measure ±3 degrees around the specular lobe centered at 30 degrees in approximately 220 increments. That’s an angular sample size of 1 sample per 1.6 minutes of arc! This allows differentiation between samples with very small differences in reflectance characteristics. Verified replacement for the older Hunter Dorigon II haze meter unit.

LBA Group, Inc
LBA Technology "Blue Line" RF inductors are based on over 30 years of proven international performance. Blue Line inductors are unsurpassed for hi-Q, stability, and low RF losses. These inductors are manufactured from heavy silver plated copper conductors and brass fittings, treated to resist tarnishing. Windings are insulated with melamine or G-1 0 epoxy laminates. These materials are recognized for their exceptional RF qualities, arc resistance, mechanical strength, and low moisture absorption. Supporting frames are engineered to permit maximum access to windings for convenience in adjustment. The metallic frames are separated by insulators to prevent induced current flow.

Sciencetech, Inc.
This solar simulator is based on a Fresnel lens to collimate the light beam from the arc lamp source to infinity, which results in highly collimated illumination of the target spot. A 2.5kW xenon ozone free lamp is used as the light source. The spectral distribution of the xenon light source, along with the use of specially calibrated AirMass filters, closely simulates the sun’s true spectral distribution in various conditions on Earth.

CAT Advanced Series -
Amperis sl
Description The Advanced CAT Series Analyzers and Timers are stand-alone or PC-controlled digital instruments for circuit breaker status evaluation. Timing channels record arc closing and opening, resistance and auxiliary contacts. The main contact channels can also measure the resistance value of pre-insertion resistors (if present in the breaker). The advanced CAT series records graphs of the opening and closing coil currents and the movements of the moving parts of the high and medium voltage circuit breaker. Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form. The advanced CAT series provides easy selection of different operating modes:

The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).
