Abstract: A radio frequency (RF) validator instrument is provided for testing functionality of a test article. The instrument includes an RF transmitter, a connection apparatus, an RF receiver, a direct current (DC) bias detector, and an RF verifier. The transmitter produces an emission signal supplied to an in-port and an out-port. The apparatus connects the in-port and the out-port to separate terminals of the article. The receiver receives said emission signal and producing a detection signal. The DC bias detector receives the emission signal through the out-port to a first voltage divider as a first bias signal, through the in-port to a second voltage divider as a second bias signal, and combining the first and second bias signals as a combination bias signal. The verifier compares the detection and combination bias signals to determine whether the article satisfies functionality.

Abstract: A stabilization adapter is provided for a portable antenna. The adapter includes a clamp, a rod and a counterweight. The clamp connects to a stand of the antenna. The rod adjustably attaches at its proximal end to the clamp. The counterweight attaches the rod at its distal end.
