The Bird Electronics Company of Cleveland (Solon) Ohio manufactures a product line of R.F. power measurement instruments primarily for the commercial and broadcast markets.  The Bird Model 43 Wattmeter is generally considered the "standard" piece of power measurement equipment and these are highly sought-after by radio amateurs.  Accuracy is rated at +/- 5% full scale. 


They are expensive as you might expect but what makes them particularly costly are the elements, or "slugs" that determine power level and frequency range.  Many commercial shops prefer the Telewave or other more costly Wattmeters especially for peak power reading applications.  For amateur use you will do very well with a Bird 43 and a couple of elements.

Manufacturer's suggest list price for the Model 43 With Type N connectors is currently (May 2014) $347.95.  Element prices range from $94.95 for elements Covering above 30 MHz.  HF elements are more expensive; $189.95 up to 1000 Watts and $289.95 for the 5000 and 10,000 Watt elements.

There is also a Model 43-P that reads peak power with an accuracy of +/- 8%.  There are several aftermarket kits available to add this feature.  The official Bird upgrade kit sells for around $180.00.
