The Bird TERMALINE 82A is a general purpose coaxial load resistor to be 
used in conjunction with transmitters which have an RF output up to 500 
Watts, over an extended frequency range of dc to 2.5 GHz. This coaxial 
load resistor is designed to match commonly used 50Ω coaxial 
transmission lines. The impedance is quite independent of frequency, and 
is almost a pure resistence. On the production units, the voltage 
standing wave ratio (VSWR) values are maintained below 1.1 to 1.0 up to 
1000 MHz. VSWR determinations for the particular resistor are tabulated 
on an individual test tag attached to each unit. Calibration is not 
normally performed for frequencies from 1000 to 3500 MHz, but experience 
shows that units checking good will be within specification in the upper 
range.

Below 50 MHz, the input impedance of the TERMILINE is very nearly a pure 
resistance value. The production tolerance on the dc resistance is ±3% 
from the nominal 50Ω, and measured exact values for this particular 
resistance are also given on the test tag.

Any Series 82 load resistor may be made to operate as a termination type 
wattmeter with the insertion of a Bird Model 43 THRULINE Wattmeter in 
series with the load. This will permit measurement of forward power 
within the usual capabilities of the TERMALINE and the THRULINE Wattmeter.
