Close up shot of the 15 Bird elements in the foam plastic holder.

Top view of the first Bird wattmeter. This meter has N-Female connectors installed and includes the blank-slug.

Photo of the second Bird wattmeter with BIRDCC1BR-1 leather carrying case (with room for six elements in the case top section), and 13 elements alongside. This meter has UHF female (SO-239) connectors and includes a blank slug.

This second Bird meter includes the Bird 4300-400 peak reading adapter. This function requires two 9-volt batteries to be installed into the holders in the back side of the meter. Batteries are not installed for storage. The storage hole slug retainer is not installed on the right side of the meter (but is present on the left side).
