Has anyone used the MFJ-4712 remote antenna switch ? The reason y I ask is I would like to hook up a onmi vertical and horizontal dipole on one mast . This item would be great to save with coax cable , with one line entering the house.I haven't seen much reviews on the web.They say breaking the coax loses signal to the radio , but two lines of coax can get expense to the radio. What do u say about the MFJ-4712? Need opinions Thanks!!!!
