I hadn't seen any for years, glad it's back on the market. We used to call it "twin-ax." What was the labeled impedance? I'll have to go to RS and see this one. Yes, if the impedance is right it would be fine for feeding a balanced load, such as a (horizontal) dipole or inverted vee. Note: a vertical dipole is not a balanced load, because one end is closer to the ground than the other. Harvey/W4TG
