A very handy device for either combing two antennas for one rig, or one antenna for two receivers. Works effectively from 500kHz up to 500MHz. Great if you have two receivers that you want to share on one antenna. The isolation is sufficient that interference from one receiver does not interfere with the other even although they are sharing the same antenna
