Bird 4410A Multi-power, ±5% Reading Accuracy, Portable Wattmeter 

This sale is for a Bird  4410A Thruline Wattmeter Only, Elements are NOT Included.

Frequency and Power Ranges are element dependent, there are no elements included. See our eBay store for a complete list of available elements.

Much improved accuracy and multiple power ranges, this is a big step up from the Bird Model 43.

7 selectable ranges, 100 mW to 10,000W, (element dependent). 

Broadband elements from 200 KHz to 2.3 GHz are available (elements are not included).

Bird 4410A Multi Power Range RF Wattmeter

• Temperature-compensated accurate CW and FM power measurements from 200 kHz to 2.3 GHz and 2 mW to 10 KW.
• Uses special 4410-series wide-range elements (elements are not included, sold separately).
• Wide-range accuracy over a 37 dB dynamic range.
• Quick Change (QC) connectors to minimize the need for adapters when making critical measurements.
• Elements are not included, sold separately, see our other eBay listings.

The Model 4410A uses the basic principles and “look and feel” of the Model 43 but transforms it into a highly accurate high dynamic range instrument. The mirrored-scale linear range meter has 2 switchable ranges, 0-1 and 0-3. Power is read as a multiple of the value indicated by the pointer, the decimal point location depending upon the range switch position and the factor printed on the plug-in element. Power ranges covered by individual elements are 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 KW and 2 W to 10 KW, full scale. For most elements, accuracy is +/-5% anywhere above 20% of full scale. The circuitry operates from a standard 9V alkaline battery.

Product Specifications:

• Accuracy: ±5% of reading for any reading above 20% of the Power Range selected for FM or CW signals without AM. This accuracy is maintained for a full 37 dB dynamic range with each 4410 Element (except No. 4410-1 200 kHz-535 kHz which is accurate to ±10% of reading, and 4410-15 1.0-1.8 GHz and 4410-16 1.8-2.3 GHz which are accurate to ±8% of reading.)
• Ambient Temperature Range: Elements 4410-1 through -8 and -10 through -16 are temperature compensated for rated accuracy from 0° to 50° C (32° to 122°F) and 4410-20 through -27 from 20° C to 30° C(68° to 86°F)
• Connector: QC Type (Female N normally supplied)
• Finish: Gray powder coat
• Frequency Range: 200 kHz to 2.3 GHz CW or FM (elements not included, see our other eBay listings for elements)
• Insertion VSWR: with N Connectors 1.25 max. to 2300 MHz
• Nominal Size: 6 7/8" H x 5 1/8" W x 3 5/8" D, (175 mm x 130 mm x 92 mm)
• Over-Range Protection: To 120%of nominal full scale (I.e. 12 W, 120 W, 1200 W, or 12,000 W).
• No damage or degradation to the unit will result, regardless of the Range Selector Switch position.
• Power Range:
• 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 kW or 2 W to 10 kW full scale in one single Plug-in Element (elements are not included).
• Any Bird Series 4410-Element may be used (see our eBay store for a list of available elements).
• Weight: 3 lbs. (1.4 kg)
• Elements are not included in this sale. They are sold Separately in our eBay store.

Multipower RF Wattmeter with ±5% Reading Accuracy

The 4410A RF Wattmeter has the basic principles and “look and feel” of the Model 43 but transforms it into a highly accurate high dynamic range instrument. The mirrored-scale linear range meter has 2 switchable ranges, 0-1 and 0-3.

Power is read as a multiple of the value indicated by the pointer, the decimal point location depending upon the range switch position and the factor printed on the plug-in element. Power ranges covered by individual elements are 300 mW to 1 KW and 2 W to 10 KW, full scale. For most elements, accuracy is +/-5% anywhere above 20% of full scale. The circuitry operates from a standard 9V alkaline battery.
