ANTENNA TESTERS HF, VHF, and UHF MEASURE VSWR, MATCH EFFICIENCY, RETURN LOSS, FIELD STRENGTH Bird’s AT-Series Antenna Testers bring a new dimension to the testing of HF, VHF, and UHF antenna systems. Powerful, yet remarkably easy to use, these instruments can test an entire band in a matter of seconds. And unlike conventional antenna testers, Bird’s advanced design provides accurate results regardless of antenna cable length.

THRULINE® WATTMETERS DELIVER RF POWER MEASUREMENTS YOU CAN TRUST The development of the first Bird Model 43 THRULINE® Wattmeter in 1952 heralded a major breakthrough in the search for a solution to quickly and easily measure radio-frequency power. It is difficult today to realize that for most of the first half century of radio communications, the most basic parameters of broadcasting could be measured only by tedious and painstaking procedures.
THRULINE® RF DIRECTIONAL WATTMETERS Advanced Power Measurement For Digital RF Signals AVERAGE-READING POWER METER MODEL APM-16 Bird developed the APM-16 for engineers and technicians who work with today’s increasingly common digital RF technology systems. The complex waveforms of many PCS, cellular, and other digitally-encoded services can depart significantly from AM, FM, and CW, making power measurement difficult and uncertain.
THRULINE® RF DIRECTIONAL WATTMETERS Model 43, Accessory Guide THE INDUSTRY STANDARD MODEL 43 The Model 43 THRULINE® Directional Wattmeter accurately measures forward or reflected power in coaxial transmission lines under any load condition. Each Model 43 consists of a line section, ”QC“ (Quick Change) connectors and an indication meter housed in a rugged, corrosion-resistant aluminum case.
THRULINE® RF DIRECTIONAL WATTMETERS Peak-Reading Wattmeter, Peak Kit for Model 43 PEP WATTMETER MODEL 4314B Portable peak-reading instrument designed specifically for measurement of air navigational aids and other pulsed RF systems — such as telemetry, radar, television, and command and control — as well as peak envelope power (PEP) measurement of SSB and AM signals.

THRULINE® RF DIRECTIONAL WATTMETERS Broadband, Multirange Wattmeters FIXED 25–1000 MHz, 5–500 WATT ELEMENT MODEL 4304A The Model 4304A wattmeter is a popular choice of wireless communications professionals. This rugged instrument is ideal for anyone who needs to quickly test multiple power and frequency ranges. The versatile 4304A uses a single, permanently mounted, 25–1000 MHz element to deliver full-scale measurements from 5 to 500 watts. A high-quality line section keeps insertion loss to less than 0.
THRULINE® RF DIRECTIONAL WATTMETERS Multipower Level, Superior Sensitivity MULTIPOWER, ±5% READING ACCURACY 4410 SERIES Our 4410 Series high-sensitivity wattmeters are solid choices for field-service applications where the greater dynamic range of the plug-in elements substantially reduces the number of elements needed to cover multiple power and frequency ranges. The 4410 series is also well-suited to laboratory work where power levels as low as 2 milliwatts must be measured with high accuracy.
THRULINE® RF DIRECTIONAL WATTMETERS Panel-Mount Wattmeters with Line Sections 0.45–2700 MHz MODELS 4521, 4522, AND 4526 Bird’s 4500 Series wattmeters are panel-mount versions of the time-tested Model 43 wattmeter. They will measure power in CW and FM systems that employ 50-ohm cable or 7⁄ 8" EIA transmission line.

ACCESSORIES Selector Switches, Directional Couplers 50-OHM COAXIAL SELECTOR SWITCHES 71, 72, 74 SERIES The unique, rugged and reliable design of Bird Coaxwitch® Coaxial Selector Switches permits positive contact, low-insertion VSWR, and negligible cross talk between channels. The switching mechanism is 41⁄ 2" of RG-87/U Teflon cable that pulls away from the mating Male N connectors and rotates to the desired switch position.
ACCESSORIES QC-Type (Quick-Change), SQC (Small Quick-Change) Connectors Many TERMALINE® load resistors, attenuators and absorption wattmeters, as well as THRULINE® wattmeters, employ our patented QC-type ”Quick-Change“ RF Connectors. These products may be ordered with the connector(s) most convenient for use with your equipment. Many customers order additional connectors to avoid using performance robbing adapters. QC Connectors are easily changed in the field by removing and replacing four screws.
ACCESSORIES Adapters, Batteries, Cables, Connectors, Coupling Kits ADAPTER KITS 4240 SERIES Bird‘s adapter kits let you assemble compact, precision 50-ohm adapters to meet up to 45 different matching requirements. The adapters offer low VSWR because of precision machining and tight mating tolerances. The N (F)/N (M) combination, for example, is below 1.05 to 1 GHz and below 1.1 to 2.5 GHz. The Model 4240-400 lets you create 30 combinations. The Model 4240-401 can fashion 45 combinations.
TECHNICAL DATA THRULINE® principle The basic sensing circuit of a THRULINE® plug-in element consists of the mutual inductance M between the loop and the center conductor and the voltage divider C and R. In Fig. 1, E is the voltage between outer and center conductor and I is the current. Elements can be rotated 180˚, resulting in either a positive or a negative M (Fig. 2 and 3).
