Terrestrial Data/Telemetry Antennas

The UL-3502-438 is a rugged, wideband, omnidirectional, medium gain, linearly polarized antenna, covering the licensed WiMax 3.5 GHz band. It measures 4 cm/1.5" OD x 11 cm/4.5" H and can be used either indoors or outdoors. SPECIFICATIONS: Frequency range: 3.4-3.7 GHz Coverage: Omnidirectional in azimuth Polarization: Linear, typically mounted for Vertical polarization (VPOL) Gain: +5 dBil Nominal Impedance: 50 ohm (RF) Input Power: 10 Watt CW VSWR: 2.0 Connector: SMA, Female (select preference...

The VL-2051-383 is an omnidirectional antenna covering the entire VHF Digital Audio Broadcast band (DAB, Band III, 174-240 MHz). DAB is the future "FM broadcast" band, popular in Europe and Asia, featuring CD quality audio broadcast over land (terrestrial DAB). The internal radiating structure is complementary and broadband. Thus, no ground plane is needed or required for normal operation. The antenna is housed in a Fiberglass enclosure making it rugged and tolerant to challenging...

The VL-4401-383 is a half-size, omnidirectional antenna covering the Low Band VHF Fire and Public Safety spectrum (42-46 MHz). In spite of its small size, this antenna will rival any full size equivalent. The internal radiating structure is complementary, and no ground plane is needed or required for normal operation. The antenna is housed in a Fiberglass enclosure making it rugged and tolerant to challenging environments. Internally, the feedpoint is DC shunted (short circuit) and...

Amateur Radio 6 Meter Band, 50-54 MHz Omni Antenna The VL-5201-383 is a half-size, omnidirectional antenna covering the Amateur 6 meter band (50-54 MHz). In spite of its small size, this antenna will rival any full size equivalent. The internal radiating structure is complementary, and no ground plane is needed or required for normal operation. The antenna is housed in a Fiberglass enclosure making it rugged and tolerant to challenging environments. Internally, the feedpoint is DC shunted...

Embeddable Flat Antenna, Custom Frequency The UL-9001-333-CF Custom Frequency, Factory Tuned, Flat Antenna was developed for applications needing a temporary or relocatable solution that is small and economical. Use it with your wireless speakers, wireless modem, cellular phone (single band only), or any other radio device operating within the range of 600-2500 MHz. This antenna can be conveniently mounted to a glass surface, or to any other non-conducting material. It may be attached behind...

Uses include: Ardis modem, Cellular phones, Cellular network telemetry/SCADA, automatic metering, ISM devices, 900 MHz communications, wireless LAN/MAN/WAN. Frequency: 800-950 MHz Coverage: Omni directional (azimuth) Polarization: Linear, Vertical Gain: +2 dBil Ground Plane: Requires no ground plane Nominal Impedance: 50 ohm (RF), Short Circuit (DC) for ESD protection (ESD = Electro-Static Discharge) VSWR: 2.0 Dimensions: 21.6cm (8.5") H x 1.3cm (1/2") OD Connector: SMA, Male, Right Angle on...
