Bird Termaline 6151 Wattmeter RF Load (New) 2-2000 MHz (Uses Model 43 Elements) Bird Termaline(c) 6151 Wattmeter and RF Load. 2-2000 MHz. The 6151 uses the standard Model 43 elements. Scales for 0.25, 0.5, 1.0, 5, 10, 25, 50, 100 Watts (scales also valid for 250, 500, etc. Watts intermittent duty). New old stock, perfect condition, specifications are guaranteed for 90 days. Bird QC connector Type N(F) input connector, 50 Ohms. Rated for 100 Watts continuous, can be used at higher power as long as the RF Load is not allowed to overheat. I've tested elements to 500 Watts in short bursts with no problems and no noticeable heating. Accuracy is +/- 5% fs to 1 GHz, +/- 8% fs from 1 GHz to 2 GHz. Detachable meter head for remote operation. This is a discontinued Bird product and a rare find in new condition. Elements are not inlcuded. |

Bird DA-140/AP RF Load and Wattmeter TS-118/AP 2-500 Watts 20-1400 MHz Similar to the Bird TS-118A/AP 500 Watt RF Load and Wattmeter In New Condition, Never Used 2-500 Watts RF Load Continuous Duty 20-1400 MHz RF Wattmeter With 4 Range Thermocouple Elements Input Type N(F) Adapter Included Simple but rugged design minimizes maintenance requirement Rugged metal carry case in perfect condition This Bird Electronic terminating wattmeter was made for the US Military. It shows no signs of use and looks works like new. This item includes the RF Load and Wattmeter, 4 thermocouple elements (plus 4 spares), tuning adapter, Type N adapters, and a very rugged metal storage and carry case. Metal drawer is missing on this unit, adapters and other parts are included. Range selection is accomplished by changing the thermocouples. Range can be changed from 2 to 500 Watts from 20 to 1400 MHz. A lookup chart on the meter cover converts the meter reading to actual watts based on the signal frequency. Use without the thermocouple adapters and it's a continuous duty RF Load for up to 500 Watts. A comprehensive manual is included that includes operation and maintenance instructions. Tested OK as compared to a Bird Model 43 and Bird 8402. Calibration is not guaranteed, sale is final as this item is difficult to ship. RF load is guaranteed to be AOK, wattmeter is not calibrated but works OK. Used in new condition. |
