The Same VSWR performance of high precision terminators costing hundreds of dollars! All 751/2 signals, once entered into a termination, must be fully converted into energy. If the impedance matching is not perfect, part of this energy will be reflected and poor VSWR will result, especially at higher operating frequencies (i.e. computer graphics, digital video, etc.). Canare now offers a precision 751/2 termination plug with performance that far exceeds (by 20 to 30 dB) other terminations at .1% tolerance. In general, these old style terminations use a 501/2 type BNC body with a 751/2 DC resistor tacked onto the back of the center of the contact pin.
