Austin Spectra 202600 Austin Spectra Multi-Band Mobile or Base Scanner or Two-Way Radio Antenna

Superb Performance with Maximum Versatility for Mobile and Base Station The Spectra is a patented Multiband design which brings you unparalleled 4 band tuned antenna performance. For mobile usage 1/2 wave elements provide coverage on UHF and 800 to 1000 MHz. Low and High Band coverage is provided by our exclusive offset fed 1/4 wave elements. The compact approximately 33" length (top whip adjustable) adapts to all vehicles or indoor applications. The Austin Spectra has a low profile Motorola NMO type connector. Thru hole body mounts and magnet mounts are available.
The pole mount
is available for the Austin Spectra as a base station adapter/converter. The pole mount also enhances the performance of Low & High Band by increasing those elements to 1/2 wave length. The Pole Mount is 48" long and uses a UHF connector (SO-239 type, mates with standard PL-259 cable connector). With the Spectra attached the overall length is approximately 7 Ft. *U.S. Patent# 4,940,989 (note: Actual Spectra and Pole may differ in appearance from drawings) NOTE: 30/150/450/800 MHZ ARE BAND CENTERS - THE AUSTIN SPECTRA WILL RECEIVE OVER A MUCH WIDER RANGE

NOTE: THE SPECTRA ANTENNA IS A NON-RETURNABLE ITEM
NOTE: MOST AUSTIN PRODUCTS ARE BUILT ON ORDER

Introduction
The broadband receivers and scanners with auto-tune, frequency scan and search capabilities have reached a fantastic state of the art level. The transition of these electronic devices from the not so long ago days of the crystal controlled units represents a quantum leap in technology. The new receivers and scanners have necessitated a need to provide broadband and multiband antennae to assure the maximum performance. While all this electronic wizardry has been in progress, similar technological advances have been made in the art of antennas.
Price
The pricing of today's scanners and receivers ranges from approximately $200 to $5000. No small investment to be sure! One of the most overlooked parts of the system is the antenna. Most scanners come equipped with either a small telescopic whip or an even smaller coiled up wire housed in a flexible rubber sheath. This latter configuration is commonly referred to as a "rubber duck". While the terms are used in relationship to antennae, it is dearly understood by anyone skilled in the art of antenna technology that they bear very little, if any, relationship to a properly designed resonant device deserving to be called an "Antenna". One would probably get just about as much performance out of a "duck" or a "whip" attached to his or her scanner. These devices could more appropriately be referred to as "Wicks", which is a device that when suspended in some medium will pick up or absorb some of the medium on its surface. As an antenna, a wick performs equally poorly on all frequencies.
Anatomy of an Antenna
Antennas commonly thought of by most people as "just a piece of wire" are anything but! The apparently simple device is in actuality the by-product of one of the most sophisticated and complex sciences known as Electromagnetics. To be classified as a real antenna the device must be properly designed: 1. To have a resonance at a specific frequency, band of frequencies or group of frequency bands. 2. To assure that the electromagnetic field created by the antenna is correctly positioned for maximum performance. 3. To present a correct feed impedance to the scanner or receiver. The Spectra accomplishes this to perfection.
