Antenna features strong materials
Antenex’s fiberglass-enclosed base antennas are for the 2.4GHz band. These 3dB gain antennas have the same outer shell design used in the company’s lower-frequency fiberglass-enclosed base stations. They also have a high-gloss, heavy-wall fiberglass radome; a finish-ground, schedule-80, gold anodized aluminum sleeve for mounting; and a gold anodized aluminum cap.
Terrain software offers 24 modules
SoftWright has released version 4.4 of the Terrain Analysis Package for Windows 9x/NT/W2K. This RF design software consists of 24 modules that, when combined, bring a broad capacity of RF system design to the PC. This software is used to perform evaluations of existing or proposed radio transmitter sites, to predict radio coverage for TV and FM broadcasting, and to design cellular, paging and two-way radio systems. The fundamental module is the basic mapping module, which handles the path terrain profiling work. For more sophisticated RF studies, the RF facilities module is added.
EMS units works as telephone or tone console
The Vega C-2000 single frequency emergency medical service telephone console from Telex Communications is a DSP microprocessor-based, single-line desktop telephone or tone console. This product is designed to operate in ring-down circuit applications using industry standard four-wire SF to E&M facility equipment. It is encased in durable, plastic housing. Features include a 16-digit dial DTMF keypad, four 10-digit memory locations and a serial port for cloning other C-2000 consoles. It also offers an LED indicating the status of the units and 2W speaker audio.
Spectrum analyzer covers satellite L-band
The PSA-45DSI spectrum analyzer from Avcom-Ramsey Technologies is designed for antenna alignment and L-band signal monitoring. This analyzer features dual input, which allows connection to two LNBs simultaneously. It covers the 950MHz-1,450MHz band, though signals just outside the band are also visible. The analyzer weighs 8lbs and uses a 6V battery pack.
Mic headset improves radio comms quality
The bone mic tactical headset from Television Equipment Associates offers mic intelligibility comparable to boom mics, which improves communications quality. The mic fits totally inside the ear and picks up voice vibrations from the user’s jawbone. The headset mic and receiver are incorporated into a tiny generic ear mold that does not substantially obstruct peripheral hearing and will not interfere with SCBA breathers
Power systems come fully assembled
NEWMAR’s rackmount power systems are fully assembled at the factory, wired and ready for shipment direct to the communications site. The systems are designed for low-to-medium power applications and were developed for time-critical site build-outs where a single dc power solution is preferred. This system incorporates rectifiers, distribution circuits, metering, status indicators, remote alarm and low voltage battery disconnect. Quick connect plug-in wiring allows change-out of modules without system shutdown.
Signaling tester simulates a base station
The MD8480A W-CDMA signaling tester from Anritsu simulates a W-CDMA base station. The tester is useful to verify the modulation and demodulation of the mobile station or chipset, to confirm the call-processing functionality between the base station and mobile station, and to simulate applications. The tester demodulates the data, then displays and compares it with the data output from the device.
Antenna platform suited for lattice towers
PiRod’s rotatable antenna mounting platform is specifically suited for lattice towers. The design allows it to be positioned to any azimuth independent of tower orientation, making it useful for collocation sites. This platform can be installed on any guyed or self-supporting tower with straight or tapered lattice sections. Its low profile reduces wind loads. It is available in 13- or 15-foot face widths. A handrail version is also available.
