this stuff was commonly used for tv antenna so my assumption is it can be used on 2m. if this assumption is incorrect please let me know. rant: dear god how many websites do we need that explain how to make a crappy jpole out of ladder line? i mean really? rant off. i'm looking at a collinear broadside array similar to the cushcraft dx-120's. the feed impedance is 300 ohms and i was thinking that a 3x3 stack with equal length twin lead would give 50 ohms at the feed point. IF i can find a pair of v8 chevys to turn the thing, it should be a decent antenna for local rag chewing. i use the word local in the relative sense.
