In receive mode, the AV-590 acts as a splitter providing signal to both radios; in transmit mode, a control signal is sent from the audio panel to the AV-590 to switch the AV-590 to the selected radio therefore isolating the remaining radio from the AV-590 electric switch. When the transmission is complete, the control signal is removed and the AV-590 reverts back into receive mode.This AV-590 antenna switch\u0026amp;nbsp;(EDMO# AV-590\/28)\u0026amp;nbsp;operates on 20 VDC to 30 VDC.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSupplied by Aeronautical Aviation.\u003c\/em\u003e\u003c\/p\u003e","brand":"RAMI","offers":[{"title":"Default Title","offer_id":44134284886094,"sku":"AV-590(28)","price":13678.56,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7169\/5182\/files\/rami-antennas-av-590-electronic-com-switch-av-590-28-av-590-electronic-com-switch-1253519148.avif?v=1786119914","url":"https:\/\/aeronautical.co.za\/products\/av-590-electronic-com-switch-20-30-vdc-118-137-mhz","provider":"Aeronautical Aviation (Pty) Ltd","version":"1.0","type":"link"}
