Outdoor Antenna Kits
These point-to-point antenna kits provide secure wireless building-to-building data communications at a 2 Mbps data rate at a range of up to 17 kilometers. The outdoor antenna solutions provide a flexible alternative to wired T1 and leased lines connecting multiple buildings in a campus or corporate environment. The antennas eliminate setup costs and monthly leased line charges and are available in both 2.4 GHz and 915 MHz frequency spectrums with a choice of security options. Each kit includes a WavePOINT II series wireless access point for connecting to both Ethernet wired and WaveLAN series external antenna modules, and a lightning arrestor. Four outdoor kits are available with a full one-year warranty. Prices: start at$2825.

UHF Fiberglass Omnidirectional Antenna
The model FRX450 UHF fiberglass omnidirectional antenna provides for transmission and reception of vertically polarized signals in the 450 to 470 MHz frequency band. The antenna is constructed of a durable fiberglass radome to withstand harsh weather environments. A highly reliable brass radiator promotes long life. The integrated pigtail and N-female connector provides waterproofing for connection between the antenna and transmission line. The antenna has a 5 dBi gain with an E-plane of 24° and an SWR of less than 1.5 (max) on 50 W impedance. The unit measures 42.25" (114.94 cm) in height and weighs 1.14 lb (0.51 kg).
20/30 GHz Dual-linear Polarized Horn
The model 9676-800 dual-linear polarized horn is designed for use in K- and Ka-band calibration systems. The unit comprises a pyramidal horn and a dual-band orthogonal-mode transducer with WR-42 and WR-28 RF ports. The horn measures 6.6" long with a 1.5" aperture and features a sealed aperture window. Additional specifications include a frequency range from 19.2 to 20.2 GHz and 29 to 30 GHz with a gain of 25.8 dBi at 2.1 GHz. Polarization is dual linear (orthogonal) and return loss is 12 dB (min). The unit features isolation of 25 dB (min).
