Well, I threw the first one together last night. It cost about $15 for the copper from home depot. The Arrow ones sure look nice, I kind-of think I could just get one of those for $35 and call it a day. On the other hand, I feel like making another J-Pole with copper from the depot and having it be the one I take places.
I still need to play with the antenna to see if it works, haven't really had a chance yet.
Oh, and I did end up getting the 8X coax... the guys at HRO pointed me in that direction. I was torn between that stuff and something else a bit thicker that they said was really nice. The guys at HRO were really a hoot to talk to. I stuck around there for about 20 minutes just chatting with them.
But dang, those arrow ones look nice...
